5.
Assign a binary input with the measuring range in which the device should return to after
completing the calibration ("Measuring range 1/2/3/4) or "Autorange" for automatic
measuring point switching). This step is necessary because the device would otherwise
remain in the calibrated measuring range.
6.
Exit function 72 and accept the changes.
Carry out calibration:
1.
Activate the "measuring range x" binary input with the necessary voltage for at least 1
second.
The device selects the corresponding measuring range.
Note
The binary input assigned to "test gas" can only be effectively activated in the "measure"
operating state! Therefore, make sure that the device is in the "measure" state.
2.
Now activate the "test gas" binary input with the necessary voltage for at least 1 second.
Via the binary input, the corresponding relay is activated such that now the test gas valve
opens and the sample gas valve closes (FIDAMAT 6-G only). At the same time, the
device switches over into the "calibration state" (shown in the measured value display
with "■ CAL") and activates the "functional check" (shown in the measured value display
with "■ CTRL").
3.
Wait until the measured value has stabilized.
Note
The "span calibration" binary input can only be effectively activated in the "calibration"
operating state ("■ CAL")!
4.
Now activate the "span calibration" binary input with the necessary voltage for at least 1
second.
The device calibrates the corresponding measuring range. At the same time, the device
leaves the "calibration state" ("□ CAL") and deactivates the "Functional check" ("□
CTRL"). It is now back in the "measuring state". Calibration is completed.
5.
Now activate the binary input, which you assigned to the desired measuring range after
calibration, for at least 1 second.
The device is now in the desired measuring range. You can continue with measurement.
