Operating Instructions
Source Resistance
Choose this function to provide a simulated resistance into any device that
measures resistance.
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 OHMS for the FUNCTION, 400Ω
or 4000Ω for the RANGE.
Disconnect all sensor wires from the devices to be calibrated and connect the
PIE 820PM to the inputs of the device using 2, 3 or 4 wires. For 2 Wire resistacne
connect the read lead into jack (1) and the black lead into jack (2). For 3 wire
resistance add a black lead plugged into jack (3) and for 4 wire resistance add
a red lead plugged into jack (4).
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 0.1Ω/1Ω increments by turning the knob
e
. Press and turn the knob
for faster dialing with 10.0Ω/100Ω increments.
