Choose this function to provide an output from 0.00 to 80.00 mV
or from 0.00 to 10.25 V. The source current is a nominal 24 mA
to provide the driving power to your voltage receivers.
Move the power switch
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 V for the FUNCTION and 10V or 80 mV for the
RANGE.
Connect the output leads of the PIECAL 820 to the inputs of the
device being calibrated, making sure to check polarity. Red lead
to the plus (+) input and black lead to the minus (-) input.
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 0.01
mV or V increments by turning the knob
. Press and turn the
knob for faster dialing with 1.00 mV or V increments.

Choose this function to measure from 0.00 to 80.00 millivolts,
0.00 to 10.25 V dc or 0.0 to 60.0 V dc.
Move the power switch
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 V for the FUNCTION and 10V, 60V or 80 mV for
the RANGE.
Connect the red input lead (+) of the PIECAL 820 to the more
positive point of the break and the black input to the more
negative point.
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
to MAX to see the highest reading and to
MIN to see the lowest reading. Press and hold the knob
to
clear the MAX and MIN readings.
