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. features are covered by
US Patent #7,248,058.

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.

q EZ-CHECK™ SWITCH
SOURCE: Instantly output two preset settings by moving the
EZ-CHECK™ switch to the “LO” position or “HI” position. 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.
For fast
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.

Basic Operation
w SOURCE/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.
e EZ-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.

FOR CONFIGURATION
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.

Double Click Menu - FEATURES
To change the Automatic Stepping settings
Double click the e DIAL KNOB at any time the unit is on and the following typical display (will be different for each FUNCTION) will appear for 15 seconds:
MAIN > EXIT (1/3) FUNCTION mA MODE SOURCE UNITS mA HART 250Ω* ON
Turn the page so the word FEATURES appears at the top of the menu.
Turn the e DIAL KNOB to move through the menu. Press the e DIAL KNOB to toggle between OFF and ON or to change the STEPS/RAMP and the STEP/RAMP TIME settings. These settings are remembered even with the power off.
EXIT MENU - exits this menu immediately and saves any changes. Menu will automatically exit after 15 seconds of inactivity.
AUTO OFF - If AUTO OFF is ON, the unit will turn off after 30 minutes of inactivity to save battery life. If AUTO OFF is OFF the unit will stay on until the POWER SWITCH is moved to the off position.

STEPS/RAMP - pressing the knob will cycle through 2, 3, 5, 11
and RAMP. The endpoints of the steps or ramp are based on the values stored in the HI and LO EZ-CHECK outputs.
2 steps will automatically switch bet ween the values stored in the HI & LO EZ-CHECK (0 & 100%).
3 steps between the HI, Midpoint and LO EZ-CHECK (0, 50 & 100%).
5 steps between the HI and LO EZ-CHECK in 25% increments (0, 25, 50, 75 & 100%).
11 steps between the HI and LO EZ-CHECK in 10% increments (0, 10, 20...80, 90 &100%).
RAMP continuously ramps up and down between the HI and LO EZ-CHECK outputs.
STEP/RAMP TIME - pressing the knob will cycle through 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 and 60 seconds.
To start the Automatic Stepping
Start automatic stepping or ramping by placing the EZ-CHECK Switch into the HI or LO position then press and hold the e DIAL KNOB for 6 seconds (the word STORE will appear on the display after 3 seconds and continue to press the EZ-DIAL KNOB) until the word STEPPING appears on the display. The word STEPPING will appear on the display anytime the selected automatic function is running. Stop the stepping by again pressing and holding the
e DIAL KNOB for 3 seconds.
BACKLIGHT - If BACKLIGHT is ON the backlight will light all the time the unit is powered up. For maximum battery life turn the backlight off when using the calibrator in areas with enough ambient light to read the display.

Operating Instructions
10-50 mA Operation - The 10-50 mA control signal predated the
now common 4-20 mA signal. Many loops with 10-50 signal have power supplies that run higher than 24 V DC.
SOURCE supplies from 0.000 to 52.000 mA with up to 40 V DC compliance which has enough power to stroke valves.
2-Wire Transmitter Simulation limits the loop current passing through it in the same manner as a 2-Wire transmitter with loop power supplies up to 60 V DC.
READ measures from 0.000 to 52.000 mA from mA outputs of controllers or to monitor the signal in a loop.
PWRM is POWER MEASURE which uses the internal loop supply of the 850 to power up the transmitter while indicating the current passing through the loop proportional to the input of transmitter which is controlled by the output of the 850.
When simulating a 10-50 mA 2-Wire Transmitter in loops with high voltage this section of the calibrator may get warm.
