Product Description
• Technician friendly operation
The unique and intuitive EZ-DIAL Double Click Menu makes it easier to
setup than other multifunction calibrators. Uses the same menus as the
single function PIE Evolution Calibrators. Icons on the display indicate where
to plug in the test leads.
• Use it as a milliamp and voltage calibrator
Source 0 to 24.00 mA, 0 to 10.25 V & -10.00 to 80.00 mV dc
Read 0 to 24.00 mA, 0 to 10.25 V, 0 to 60.0 V and -10.00 to 80.00 mV dc
Simulate 2-Wire Transmitters & Power up transmitters & loops
• Calibrate in temperature with 0.1°C/°F resolution
Stop carrying around a millivolt source and thermocouple tables. The PIE
820PM works with the thermocouples you use including types J, T, E, K, R,
S, B, N, G, C, D, L (J-DIN), U (T-DIN) and Platinel II. Pt 100 Ohm (3850,
3902, 3916, 3926) & 100 Ohm (3850) RTD; Copper 10 & 50 Ohm, Nickel
100 and 120 Ohm RTD. Guaranteed compatible with all instrumentation.
• Quickly set any 3 outputs Plus automatic step & ramp
Easily set any value quickly with the adjustable “DIAL” plus store any three
temperatures for instant recall with the EZ-CHECK™ switch. Choose
between 2, 3, 5, 11 steps and ramp to automatically increment the output in
100%, 50%, 25%, 10% of span or continuously ramp between span and
zero. Select the step time to match your system from 5, 6, 7, 8, 9, 10, 15, 20,
25, 30 and 60 seconds.
• Compatible with all process instruments
Connect directly to the thermocouple inputs of smart transmitters, PLCs,
DCS and multichannel recorders and verify their outputs or displays.
•Measure temperature sensors, frequency pickups, mA & V
Check the values of your process sensors. Instantly recall MAX and MIN
values to see process variability.The PIE 820PM measures thermocouple or
RTD probes in degrees C or F.
• Checkout resistance instruments, loop & wiring problems
Source and read resistance from 0.0 to 401.0 and 0 to 4010 ohms. ‘Beep’ out
connections with the built-in continuity checker.
• Checkout flow and vibration systems
Source & read frequency from 0 to 2000 CPM (Counts-Per-Minute), 0.00 to
999.99 Hz, 0.0 to 9999.9 Hz and 0.000 to 20.000 kHz.
• Easy to read
Turn on the backlight & easily see the display in dark areas of the plant.

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 820PM 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 820PM will display the current input
value. Slide the switch to HI and the
highest value measured since turn-on or
reset will be displayed; slide the switch to
LO and the lowest value measured since
turn-on or reset will be displayed.
wSOURCE/OFF/READ Switch
Select “SOURCE” to output mA, V, T/C,
Ω, RTD or Hz.
Select “READ” to read mA, V, T/C, Ω,
RTD or Hz.
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.
Double Click the EZ-DIAL knob to
change the function of the calibrator
and to select ranges, units and other
user settings.

Configuration
Double Click Menu - STEPPING, AUTO OFF & BACKLIGHT
To change the Automatic Stepping settings
Double click the eDIAL KNOB at any time the
unit is on and the following typical display (will
be different for each FUNCTION) will appear for
15 seconds:
Turn the eDIAL KNOB to move to the second
menu (FEATURES) page.
Turn the eDIAL KNOB to move through the
menu. Press the eDIAL 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.
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.

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 eDIAL 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 STEP

STORING HI and LO EZ-CHECK Outputs
Choose this function to provide a simulated thermocouple signal into controllers, temperature
transmitters, indicators or any other input device that measure thermocouple sensors.
1) Store your high (SPAN) output temperature by moving the EZ-CHECK switch to the HI position
and turn the eEZ-Dial knob until the desired temperature 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 temperature by moving the EZ-CHECK switch to the LO position
and turn the eEZ-Dial knob until the desired temperature 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 temperature outputs by moving the EZ-CHECK switch
between HI and LO.You may also select any third temperature output (such as mid-range) using
the SET position on the EZ-CHECK switch.

Operating Instructions
SOURCE mA / SOURCE % (Percent of 4 to 20 mA)
Choose this function to provide an output from 0.00 to 24.00 milliamps. The
compliance voltage is a nominal 24 VDC to provide the driving power to your
milliamp receivers.
Move the power switch w to SOURCE then Double Click the EZ-DIAL knob to
get into the Double Click Menu. Turn the knob to scroll through the settings and
press the knob to make your selection. Select mA for the FUNCTION and
SOURCE for the MODE. Choose either mA or % and whether you need the
250ΩHART resistor active in the loop.
Connect the output leads of the PIE 820PM to the inputs of the device being
calibrated, making sure to check polarity. Red lead from jack (5) to the plus (+)
input and black lead from jack (6) to the minus (-) input. Open loops and signals
above the maximum scale are limited by protection circuitry with “ERROR” or
“OVER RANGE” flashed on the display and the red OVERLOAD LED lit.
Instantly output your SPAN and ZERO output settings by moving the EZ-CHECK
switch between HI and LO (defaults to 20 & 4 mA).You may also select any third
output setting (such as mid-range) using the SET position on the EZ-CHECK
switch. The output is adjusted in 0.01 mA (0.1%) increments by turning the knob
e. Press and turn the knob for faster dialing with 1.00 mA (10.0%) increments.
