Choose this function to provide a simulated RTD signal into controllers, temperature transmitters,
indicators or any input devices that measure RTD sensors.
1) Disconnect the RTD sensor from the device to
be calibrated.
2) Select “
SOURCE
” with slide switch
w
.
3) Connect the PIECAL 211 to the device using 2,
3 or 4 wires matching the connections of the
sensor that was just removed.
The output is adjusted in 0.1° (or 0.01/0.1 ohm)
increments by turning the knob
e
while the

q
is in the “HI”, “LO” or “SET”
position. Press and turn the knob for faster dialing
with 10° (or 1.00/10.0 ohm) increments.
The OVERLOAD indicator will light if excessive
voltage or current is detected by the calibrator.
