1. PRINCIPLES OF SAFE USE

before you start to use the device, become familiar with the present instructions;

ensure proper operating conditions, as specified in the user’s technical data (humidity, temperature)

The device is designed so as to ensure an appropriate level of immunity to most interferences that may

occur in industrial environments. In environments of unknown level of interferences,

it is recommended to implement the following measures so as to prevent potential interference with the

operation of the device:

avoid running instrument (signal) cables in the direct vicinity of and parallel to power and supply cables;

it is recommended to use twisted pair signal cables;

in the case of sensing resistors in 3-wire connections, use identical wires;

avoid proximity of remotely controlled devices, electromagnetic meters, high power loads, loads with

phase or group power control, and other devices that cause high impulse disturbances;

2.GENERAL CHARACTERISTICS OF THE CALIBRATOR

the purpose of the device is to measure and simulate temperature sensors

universal input/output (programmed from the keyboard):

the sensor with line resistance compensation

- thermocouples...J, K, S, B, R, T, E, N, automatic or constant compensation of reference joint

temperature

- linear…………... voltage (mV), resistance

diagnostic functions facilitating detections such defects in tested circuits as:

- lack of excessive value of current polarizing a resistance sensor (in a simulation)

- short circuits in a voltage signal measurement circuit (in a simulation of thermocouples and mV)

- short circuits or interruptions in sensor circuits (in measurements)

quick and simple readout:

- type of sensor set

- working direction (input/output)

- battery charging level

- current polarizing a resistance sensor (in a simulation)

- type of detected connection in a resistance sensor (2- and 3-wire)

- reference joint temperature in a thermocouple sensor (in a simulation and in measurements)

NOTE:

After the calibrator is switched on in the measurement mode, an error signal may be shown in the display

that indicates that no sensor or a sensor different than the factory-defined sensor in the configuration

parameter is connected to the device. If this happens, connect the proper sensor or set the correct

parameter 0: StYP (chapter 6, Table 1)

- sets the operating mode: input - IN (measurement) or output - OUT (simulation)

- accesses the parameter configuration mode (press for more than 2 seconds in the

measured/set value display mode),

- shows the type of sensor set (in the measured/set value display mode)

- edits the current parameter in the configuration mode (display of the parameter value),

- approves the edited parameter value, (in the text, it is designated as SET),

- increases the set value by the preset step (parameter 9:StEP, chapter 6) in simulations

- increases the parameter value in the configuration mode, (in the text, it is designated as ),

- moves to the next parameter,

- decreases the set value (parameter 10:SEt, chapter6) by the preset step in simulations

- decreases the parameter value in the configuration mode, (in the text, it is designated as

), moves to the previous parameter,

- cancels the change of the edited parameter (and displays the parameter name again)

- returns to the measured/set value display mode (must be pressed for more than 1 second)

+ - changes the set value (10:SEt) to the upper limit of the range of the simulated sensor or to

the value of parameter 8:LiHi (the lower of the two values)

+ - changes the set value (10:SEt) to the lower limit of the range of the simulated sensor or

to the value of parameter 7:LiLo (higher of the values)

- shows the battery voltage:- 0% - voltage < 2.2 V (low level),

- 100 % - voltage > 2.6 V (high level)

+ - shows the current polarizing a resistance sensor in a simulation in [µA]

- type of detected connection for a resistance sensor (2- and 3-wire) in measurements

6. PROGRAMMING OF CONFIGURATION PARAMETERS

press the CONF button until (approx. 2 s) the display shows the following temporary message:

ConF or CodE (if password protection is set, i.e. parameter 15:Prot=on),

if password protection is on, the display shows 0000 with the 1st digit blinking; use keys and to

enter the password (default parameter 16:PASS=1111), to move to the successive positions and to

approve the entered code, use the SET key,

after you enter the configuration menu, the mnemonic name of the first parameter is displayed (StYP),

by pressing the button, you can move to the next parameter, and by pressing the button - to the

previous parameter (StYp↔rrtd↔cJtY...), a list of the configuration parameters is presented in Table 1.

to change or view the value of the current parameter, press SET (edition of the parameter),

by using or , you can change the value of the current parameter,

by pressing SET again, you can save the edited value and return to the parameter name display

(e.g.FiLt),

in the parameter edition mode, by pressing ESC for a short time, you can cancel the changes and

return to the parameter name display mode,

you can exit the configuration parameters programming mode by pressing ESC for a long time, or

automatically after approx.2 minutes of idle condition,

in the normal mode, the measured or set value is displayed,

in the event of a difference between the measured/set value and the actual one, it is possible to tune the

zero point and the sensitivity to the specific sensors - parameters 11: cALo (zero point)

and 12: cALG (sensitivity).

Notes:

(1) - for FiLt=4 the response time is approx.0.7 s, for FiLt=15 - approx. 2.3 s. A higher filtration

rate means a smoother measurement value and a longer response time. The parameter

also applies to measurements of the current polarizing the (thermo)resistance output (in the

simulation mode).

(2) - does not apply to the resistance sensor (StYP=rES) and the voltage sensor (StYP=u55)

for which the resolution is equal to, respectively:0.1Ω and 0.01 mV,

(3) - when Prot=oFF, access to the parameter configuration does not require a password,

(4) - this is the time from the last use of any button

7. SETTING OUTPUT SIGNAL VALUES

By pushing or in the simulation mode (OUT), you can change the set value by the preset step

(parameter 9:StEP). By pressing SET and at the same time, you set the output to the lower of the following

values: the upper limit of the simulated sensor or the value of parameter 8:LiHi; by pressing SET + at the

same time, you set the output to the higher of the following values: the lower limit of the simulated sensor or

the value of parameter 7:LiLo. Also, the output signal can be set in the parameter programming mode

(parameter 10:SEt).
