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.

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.

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

Choose this function to provide a simulated thermocouple signal into controllers,
temperature transmitters, indicators or any input devices that measure
thermocouple sensors.

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 T/C for the FUNCTION, °F or °C
for the UNITS, T/C Type (J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) or
P (Platinel II) and internal COLD JUNC ON or OFF (ON is the default).

Connect the PIE 820PM to the inputs of the device being calibrated using the
proper type of thermocouple wire via the miniature thermocouple socket.

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. The output is
adjusted in 0.1° increments by turning the knob e. Press and turn the knob for
faster dialing with 10.0° increments.
