16-1 RTD CALIBRATION PROCEDURES
Power panel meter for at least 30 minutes.
Enter menu program, go to the CAL mode. Press the down
button and hold for approximately 1.5 seconds until the meter
reads SHRT , then release the button. Failure to hold the button
for 1.5 seconds will terminate the calibration process.
Install jumpers between terminals 5, 6, and 7 using copper
wire. Press and release the enter button. Wait until 50mV
appears. Disconnect jumpers.
Press the down button to skip 50mV input.
Now that 100 ohm appears, install jumper between terminals
6 and 7, and insert the 100W resistor into terminals 5 and 6.
Then press and release the enter button. This simulates a 3
wire RTD. Wait until CJC appears. Disconnect jumper and
resistor.
Press the up button to save and exit calibration, then press the
enter button three times until V3.1 appears. Calibration is now
complete.
