Read Resistance & Check Continuity
Choose this function to measure resistance or check continuity.
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 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
resistance and below 100.0Ω is measured.
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.
Resistance Source
Choose this function to provide a simulated resistance into any
device that measures resistance.
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 OHMS for the FUNCTION, 400Ω or 4000Ω for
the RANGE.
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
0.1Ω/1Ω increments by turning the knob
. Press and turn the
knob for faster dialing with 10.0Ω/100Ω increments.
