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 “BAT” 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.

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.

Read RTD Sensors
Choose this function to measure temperatures with an RTD
probe or sensor.
Move the power switch

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. You must also select the WIRE
MODE for 2W, 3W or 4W to match the 2, 3 or 4 wires on the RTD
sensor.
Disconnect all wires from the sensor and connect the PIECAL
820 to the inputs of the device using 2, 3 or 4 wires.
Signals above the maximum scale are limited by protection
circuitry with “OVERRANGE” flashed 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
