The following display appears on the LCD:
Once calibration has been performed successfully, the program returns to the menu titled CALIBRATE MEAS.
RANGES (figure 13-1).
If an error occurs during calibration or this process is interrupted with the F1 key [STOP], a corresponding
warning/error message is issued and the program returns to the menu displayed in figure 13-2.
Note:
This menu can be used for digital calibration of the individual measurement ranges. The values of the
reference resistances should lie in the middle of the respective measurement ranges. For this purpose,
we recommend using the calibration resistances of the 1240 series with a DKD/DAkkS certificate
(Deutscher Kalibrierdienst).
If the device is re-calibrated in any measurement range by a user, the corresponding calibration
performed by the manufacturer is overwritten. For this reason, all changes made by the user should
be carefully documented. The reading of the CAL counter (page 25) should be noted here.

The housings of measuring resistors having values

Ω
must remain connected
to the ground terminal of the RESISTOMAT
®
model 2329 while measurements are in
progress. If not, the measurement results might be corrupted by interference from
50-Hz fields.
If the entire RESISTOMAT
®
model 2329 needs to be calibrated, including the Pt100
input, 0-10 V / 0-20 mA input, 20 mV operating mode etc., the RESISTOMAT®
model 2329 should be sent back to the manufacturer because additional calibration
equipment is required in this case.
