General Information

The PIE Model 850 is more than a multifunction

calibrator. It is also a loop detective that is able to

diagnose common problems that other test

equipment just can’t find. Have a flooded junction

box or unknown ground faults? Our Loop Diagnostic

technology will detect it. Or use the LoopScope to

see at a glance all the parameters - milliamps,

voltage and resistance - in the loop.

Diagnostic

features are covered by

US Patent #7,248,058.

Patented Diagnostic Technology - Available only

with PIE Calibrators!

Operating Instructions

FIELD & BENCH USE

PIE 850 comes with a carrying case designed for hands-free

operation and a rubber boot with a built-in tilt stand. The PIE 850

is held in the case by elastic straps for use with the carrying

case open. The tilt stand is easily raised by pulling the stand until

it locks into place.

CHANGING BATTERIES

Low battery is indicated by a battery symbol on the display.

Approximately one to four hours of typical operation remain before

the PIE 850 will automatically turn off. To change the batteries

remove the rubber boot and remove the battery door from the

back of the unit by sliding the door downward. This allows access

to the battery compartment. Replace with four (4) “AA” 1.5V

batteries being careful to check the polarity. Replace the battery

door and replace the boot. All stored configuration options (T/C

Type, EZ-CHECK Memories, etc.) are reset to factory settings

when the batteries are removed.

Note: Lithium batteries are supplied and recommended for typical

battery life and performance.

Operating Instructions

STORING HI and LO EZ-CHECK Source Outputs

Speed up your calibration by storing Span & Zero output setting

for instant recall with the EZ-CHECK switch.

1) Store your high (SPAN) output temperature by moving the

EZ-CHECK switch to the HI position and turning the EZ-Dial

knob until the desired output value is on the display. Press

and hold the EZ-Dial knob until STORED appears to store

the value. Release the EZ-Dial knob.

2) Store your low (ZERO) output value by moving the EZ-CHECK

switch to the LO position and turning the EZ-Dial knob until

the desired output value is on the display. Press and hold the

EZ-Dial knob until STORED appears to store the value.

Release the EZ-Dial knob.

3) Instantly output your SPAN and ZERO output settings by

moving the EZ-CHECK switch between HI and LO. You may

also select any third output setting (such as mid-range) using

the SET position on the EZ-CHECK switch.

Connections

PIE 850 has banana jacks compatible with unshielded or

retractable banana plugs. Included with your calibrator are a pair

of test leads with alligator clips for mA, V, pH & Hz connections.

Four test leads with spade lugs are also included for 2, 3 and 4

Wire RTD connections. Thermocouple connections are made

through a miniature thermocouple socket.

qEZ-CHECK™ SWITCH

SOURCE: Instantly output two preset settings by moving the

EZ-CHECK™ switch to the “LO” position or “HI” position.

For fast

three point checks select the “SET” position. The PIE 850 will

remember the last “SET” value, even with the power off.

These values can easily be changed to suit the calibration requirements.

The values stored in the HI and LO positions are also used for Auto

Stepping.

READ: Slide the switch to the SET position. The PIE 850 will display

the current reading from the sensor or device being measured. Slide

the switch to MAX and the highest value measured since turn-on or

reset will be displayed; slide the switch to MIN and the lowest value

measured since turn-on or reset will be displayed.

wSOURCE/OFF/READ Switch

Select “SOURCE” to output mA, V, pH, T/C, Ω, RTD or frequency.

Select “READ” to read mA, V, T/C, Ω, RTD, pressure or frequency.

Select “OFF” to turn off the 850.

eEZ-DIAL™ KNOB

SOURCE: Turn the knob to adjust the output level. Turn clockwise

to increase the output, counter clockwise to decrease the output in

one least significant digit step at a time. Push down and turn the

EZ-DIAL knob for faster dialing.

Press and hold the knob for two seconds to store desired

EZ-Check™ HI/LO points in SOURCE mode. Continue to press and

hold the knob for two more seconds to start the automatic ramping.

READ: Press and hold to transfer the current temperature

into the EZ-Check™ MIN/MAX points. This clears the MIN/

MAX readings which will update as the input value changes.

SELECTING FUNCTIONS

The EZ-DIAL knob is used to setup the PIE 850 to match the

instrument to be calibrated or signal to be measured. Each time

you turn on the PIE 850 the LCD displays the screen below for

about 1 second followed by operating in the function used the

last time it was operated.

Double Click the EZ-DIAL knob to change the function of the

calibrator and to select ranges, units and other user settings.

Each function (mA, V, T/C, Ohms, RTD, Frequency) has up to

three pages of menus. The first menu page has settings for the

function and the last menu page has settings for STEPPING,

AUTO OFF and BACKLIGHT. Settings are remembered even

with the power off but are reset when the batteries are changed.
