Calibration
Calibrating an RTD option card involves a different procedure than
for other analog input cards. However, you access the card in the
same manner as other cards.
[CAL]
1. Press the
key to enter the Calibration Program.
[Fx]
2. Press
to calibrate the desired slot. (The option bar will include
a slot listing for each installed option card.)
If you have installed an RTD option card, the following screen
appears:

last option selected
Probe
Numer
The Probe option allows the meter to calculate the temperature vs.
resistance curve, based on input from the RTD in a temperature bath
or from an RTD calibrator. The Numer option forces the user to
calculate and input the curve values numerically.
IMPORTANT:
Use only one option for RTD calibration. Do not try
to calibrate with both options.

4. Press
to enter the set point temperature (formerly known as
the zero point). This temperature should be at the low end of your
expected operating range.

6. Press
to
the entered temperature, or
calibration. In either case, the screen returns to the
prompt.

7. Press
to enter the slope point temperature. This temperature
should be as far from your set point as your temperature bath will
allow, within the range -100° to +350°C (-148° to +592°F).
8. Enter the desired slope point temperature, and press
