Backlight

When the instrument is operating in low-light conditions a photocell will detect this situation and turn the backlight

on.

Temperature Logging

It is necessary for the temperature to be stable before logging temperature. The display arrows will flash 3 times when

the temperature reading has stabilized.

If you wish to log the temperature, Press the “down” button once until LOG is displayed. Press the “Select” button

once to save a reading. An acknowledgment of a saved reading will occur with a display of “LOG 1-10”. This can be

repeated for up to 10 saved readings.

The logged temperatures can be accessed from the MEMORY menu. Logged temperatures will display with the LOG

icon and a prefix (1,2,3,4,5,6,7,8,9,0) corresponding to the previously logged readings. The up/down buttons can be

used to advance through the readings. Select EXIT to return to the temperature display.

Logged readings will be retained even after the unit is powered off. Logged readings can be cleared by going to the

Memory section of the Menu and selecting CLR LOG. New readings cannot be taken until the readings are cleared.

USB Memory

A micro-usb connection is available on the circuit board allowing access to calibration & logged data.

Warning: Do not access the circuit board in a hazardous location.

Lowest, Highest & Average readings

The lowest, highest and average readings can be accessed through the MEMORY menu. The readings are indicated

by the LOW, AVG or HIGH icons on the display. These readings are not related to the logged readings, but are

determined from the temperature when the unit is powered on. These readings are deleted after the unit is powered

off.

Display Codes

The TP7-D or TP9-A can use either 2-wire or 3-wire probe assemblies.

ThermoProbe replacement probe assemblies are available in different configurations. The cable length is available in

lengths up to 50 meters or 165 feet. Standard brass markings are available applied in 5 feet or 1 meter increments. The

sensors are available with 4 weight types. The probe assembly part configurations are as follows:

REPLACING THE PROBE ASSEMBLY

NOTES:

1) Replacement of the probe assembly requires re-calibration of the device. Replacement should only be

done by experienced personnel and if calibration equipment is available.

2) Please refer to IEC/EN 60079-19 (Explosive atmospheres - Part 19: Equipment repair, overhaul and

reclamation) when making the repair.

3) Only use replacement probe assemblies obtained from ThermoProbe, Inc. or one of its authorized

distributors.

a) First follow REPLACING BATTERY instructions a through c to remove batteries.

b) On the circuit board push the terminals clamps down and remove the wires noting the wire lead color code

arrangement. See Figure 1.

White – positive sensor wire

Green – cable compensating wire (not used on 2 wire models)

Silver – negative sensor wire & shield wire

c) Set the cover and circuit board aside and remove the strain relief knot in cable assembly.

d) Unwrap the cable from the assembly and pull the cable free of the rubber grommet.

e) Insert the new cable wire through the rubber grommet and then pull several inches of cable past the grommet.

f) Tie a simple overhand knot in the cable at the grommet for strain relief and pull the knot up to the grommet.

g) On the circuit board, push the terminal clamp levers down and insert the new wire leads according to the terminal

color codes. The label indicates how to connect a 2 wire probe vs. a 3 wire probe (includes green wire). See Figure 1.

CALIBRATION PROCEDURE

The calibration mode should only be accessed by qualified personnel with proper equipment; otherwise

calibration integrity may be compromised. Read the following instructions carefully.

At least 2 points are required to make an adjustment. (2-Point calibration). Additional points can be taken

(3-Point or 4-Point calibration) to calibrate a large range of temperatures (e.g. 0°F to 300°F) or if you want

to match specific points in your range. You should include points at the bottom and top of the range. You

must have the proper equipment for every point of calibration.

Do not attempt to calibrate the instrument if the low battery indicator has been displayed since the new

calibration values may not be properly stored to memory.

Refer to API 7.2 or another recognized standard for routine calibration verification recommendations.

Calibration must not be performed in any environment considered to be hazardous.

Equipment needed:

Ice Bath or other low temperature bath with reference thermometer.

Warm to hot fluid bath between 20°C (approx 68°F), or higher up to 90°C (approx 194°F) with reference

thermometer. (see Note)*

Optional high temperature oil bath at about 150°C/300°F and reference thermometer.

*Note for limited calibration: If entire range capability of instrument is not required, the 2 point high adjustment

can be made at a temperature relatively close to the common temperature of the liquid measured and accuracy

will be maintained within the limited range. For example: If liquid product to be measured is commonly less than

38°C (approx. 100°F), then a “high point” calibration can be made near that temperature. Temperature accuracy

above this calibration point cannot be assured.

To calibrate proceed with the following steps:

1. Enter calibration mode by going to CALIBRAT in the selection Menu. When this is selected, the user will be

prompted to enter a 3 digit password. Using the “up/down” buttons allows each digit to be adjusted. Once the

correct value is set, advance to the next digit by pressing the “select” button. After the 3rd digit is set press the

“select” button to enter Calibration mode. If an incorrect password is entered, FAIL will display and the unit

will return to temperature mode. Once in Calibration mode the ‘CAL’ icon on the display will blink. The

calibration mode password is: 112

2. Select ADJUSTfrom the calibration menu and then select the desired number of calibration points. Pick

2PT CAL, 3PT CAL or 4PT CAL using the select button.

NOTE: If the user is not ready to enter the calibration mode, the EXIT option can be chosen.

10/2017, JK

3. The device is now in adjustment mode. The display will show ADD PT1. The “up/down” buttons can be used

to select a different point to adjust or CANCEL. If the CANCEL option is chosen then the calibration

procedure is exited and the prior calibration values are re-activated.

ADD PT1 = Lowest temperature point

ADD PT2 = the next higher temperature point

ADD PT3 = the next higher temperature point (only used in 3-point calibration or 4-point calibration mode)

ADD PT4 = the highest temperature point (only used in 4-point calibration mode)

ADJ DONE = Save and exit calibration mode (all points adjusted & valid)

CANCEL = Exit calibration mode without saving

Pick which point to adjust and press the select button to begin. The current temperature will display and the

CAL icon and the number of the point to adjust will now be blinking.

NOTES:

oCalibration can be performed to hundredths of a degree.

oThe up/down buttons can be used to increase or decrease the display reading.

oHolding the up/down buttons adjusts 0.1 degrees increments.

oMomentary Presses of the up/down buttons for less than 0.5 seconds adjusts 0.01 degrees for every

press.

oThe display arrows will flash 3 times when the temperature reading has stabilized.

oAll points must be saved before selecting ADJ DONE. A DATA ERR message will display if all

points have not been saved or are not in increasing temperatures. (Ex: PT1 = 32F, PT2 = 120F, PT3

= 250F)

oWhile in calibration mode the temperature will display based on the prior calibration curve.

oThe RESETCAL feature can be used to return the unit to a factory calibration curve.

(calibration/adjustment will still be required).

oThe RESETCAL (reset to factory calibration) feature should be used if the probe is replaced using

a 2-wire assembly instead of a 3-wire assembly or if prior calibration has caused the unit to read

excessively out of tolerance.

4. Once the temperature has stabilized, using a reference device check the actual temperature in the bath and use

the “up/down” buttons to adjust the device to the actual temperature. Once the device temperature matches the

actual temperature, press the select button to save the setting. The display will show SAVE or EXIT. If

EXIT is selected it will return to the ADD PT1 menu. Once SAVE is selected the display will advance to the

next temperature point for adjustment showing ADD PT…. The up/down buttons can be used to select a

different point to adjust or CANCEL. If the CANCEL option is chosen then the calibration procedure is exited

and the prior calibration values are re-activated.

oNOTE: Once SAVE is selected the temperature display will return to the previous reading until the

calibration is completed.

oNOTE: If SAVE is selected before the temperature has stabilized, the display will show NOT

STABLE. Wait for the temperature to stabilize before saving.

5. Move the probe to the next bath and repeat step 4. After you save the highest temperature point the display

will flash READY and the new calibration settings will be in effect. The buttons will now resume their

normal operating functions. The calibration settings are saved to flash memory when the device is turned off.

The unit will not turn off automatically. Manually turning the unit off saves the calibration data.

SAFETY INSTRUCTIONS - TP7-D & TP9-A REV 102017

These ThermoProbe instruments are intended for use in both hazardous (potentially flammable or explosive) and non-

hazardous areas under dry conditions at ambient temperatures between -20 to 40°C.

The instruments are not intended for use in permanent outdoor installations and are not intended or tested for icing

conditions. Additional means of protection should be used where the equipment may be exposed to excessive external

stresses (e.g. vibration, heat, impact, etc.). The user must have a working knowledge of appropriate safety

requirements.

a) The user must have a thorough knowledge of the products to be measured and must know of the safety precautions

to be taken when working with the material to be measured.

b) The instrument shall be checked concerning severe defects; check that instrument is complete (including

grounding/bonding cable), has good batteries, etc. If necessary, check measurement accuracy. If any defects are

found, the instrument should not be used until repairs have been made.

c) The instrument, especially cable and probe, should be clean for safety and ease of use.

d) The physical measurement location should be evaluated for primary and secondary risks.

e) Power source must be removed before performing any maintenance.

f) Exchange of components other than the batteries may compromise ATEX/IECEx or other certifications and shall

only be undertaken by ThermoProbe or one of its qualified service providers. See also “Authorized Repair” section.

g) To reduce the risk of fire or explosion, this device must be bonded to the vessel according to clause 6.3.2 e),

IEC/EN 60079-14 before and during introduction into the vessel and shall remain bonded until the sensor probe is

completely withdrawn from the vessel.

h) The device must remain bonded to ground/earth using the provided connection whenever a hazardous atmosphere

could be present as well as during situations where electrostatic charging can occur such as the unwinding/winding of

the thermometer cable or filling or emptying of the tank.

CAUTION: In the event that any part of the instrument should become electrostatically charged in a potentially

hazardous location, follow company policies for testing and clearing the area of any hazardous gases before

attempting to bond the instrument to earth ground. If this is not possible allow sufficient time for the instrument to

naturally dissipate any charges before attempting to bond to earth ground. Given the atmosphere, this could take

several hours.

GUIDANCE NOTE

Problems with aggressive substances and environments: Be aware of aggressive substances and that extra protection

may be needed.

Caustic soda, highly basic and acidic substances will erode aluminum and copper ground clip and wire. The Sensor-

Cable assembly has external surfaces of stainless steel and fluoropolymer material. Exposure to Excessive heat can

melt the plastic components of the instrument.

SAFETY APPROVALS FOR TP7-D AND TP9-A:

AExiaIIBT4Ga

Applicable Standards are: Agency or Safety Designation

IEC 60079-0:Ed 6, IEC 60079-11:Ed 6 IECEx

EN 60079-0:2012 + A11 3013, EN60079-11:2012 Europe: ATEX

INTRINSIC SAFETY

Intrinsically safe equipment is defined as "equipment and wiring which is incapable of releasing sufficient electrical

or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture

in its most easily ignited concentration." (ISA-RP12.6) This is achieved by limiting the amount of power available to

the electrical equipment in the hazardous area to a level below that which will ignite the gases.

In order to have a fire or explosion, fuel, oxygen and a source of ignition must be present. An intrinsically safe system

assumes the fuel and oxygen is present in the atmosphere, but the system is designed so the electrical energy or

thermal energy of a particular instrument loop can never be great enough to cause ignition.

BATTERIES

WARNING:

Batteries must be changed in Non-hazardous area.

Batteries must be of correct approved type.

Batteries must be installed with correct polarity making sure the (+) end of the battery is aligned with (+)

symbol embossed in the battery case.

New batteries must not be mixed with old batteries.

Batteries must not be mixed with batteries of other models or manufacturers.

Batteries must not be installed with polarity reversed where one cell could charge another cell.
