Operating Instructions
FIELD & BENCH USE
PIECAL 820 comes with a carrying case designed for handsfree operation and a rubber boot with a built-in tilt stand. The
PIECAL 820 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 PIECAL 820 will automatically turn off. To change the batteries;
remove the rubber boot, 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: Alkaline batteries are supplied and recommended for
typical battery life and performance. Optional rechargeable
batteries (charged externally) are available.

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
PIECAL 820 has banana jacks compatible with standard banana
plugs or retractable safety banana plugs. Included with your
calibrator are a pair of test leads with alligator clips for mA, V &
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.

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: 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 PIECAL 820 to match
the instrument to be calibrated or signal to be measured. Each
time you turn on the PIECAL 820 the LCD displays the following

values stored in the HI and LO EZ-CHECK outputs.
2 steps will automatically switch between the values stored in
the HI & LO EZ-CHECK (0 & 100%).
3 steps between the HI, Midpoint and LO EZ-CHECK (0, 50

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 STEP appears on the display. The word
STEP will appear on the display anytime the selected automatic
function is running. Stop the stepping or ramping 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.

Read Resistance & Check Continuity
Choose this function to measure resistance or check continuity.
Move the power switch
w to READ 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 OHMS for the FUNCTION, 400Ω, 4000Ω or
Continuity for the RANGE. You must also select the WIRE
MODE for 2W, 3W or 4W to match the 2, 3 or 4 wires being used
to measure resistance. For continuity the only choice is 2W.
Disconnect all wires from the sensor and connect the PIECAL
820 to the inputs of the device using 2, 3 or 4 wires.
If continuity is selected, resistance is measured up to 400.0Ω.
The beeper will sound and
)))) appears on the display when
resistances below 100.0Ω are measured.
Signals above the maximum scale are limited by protection
circuitry with “OVER RANGE” on the display and the red
OVERLOAD LED lit.
The PIECAL 820 measures the input signal and constantly
updates the display with the current reading. Move the
EZ-CHECK switch
MIN to see the lowest reading. Press and hold the knob
q to MAX to see the highest reading and to
e to
clear the MAX and MIN readings.

Source RTD
Choose this function to provide a simulated RTD signal into
controllers, temperature transmitters, indicators or any input
devices that measure RTD 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 RTD for the FUNCTION, °F or °C for the UNITS
and RTD (Choose from one of Platinum 100Ω, or 1000Ω, Copper
10Ω or 50Ω, Nickel 120Ω or 110Ω curves). Note: Pt 100Ω 3850
is the most common RTD type.
Disconnect all sensor wires from the devices to be calibrated
and connect the PIECAL 820 to the inputs of the device using 2,
3 or 4 wires.
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.

Source Frequency
Choose this function to provide a frequency signal into any input
devices that measure frequency.
Move the power switch

to scroll through the settings and press the knob to make your
selection. Select FREQ for the FUNCTION and 20KHZ,

Disconnect all input wires from the devices to be calibrated and
connect the PIECAL 820 to the input of the device matching
polarity.
The green HZ SYNC LED pulses in synch with the output pulses
and may be used to calibrate optical pickups. The output signal
is a zero crossing square wave with a fixed amplitude of 6 V
peak-to-peak from -1 and + 5 V.
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
