Example of scan calibration
Calibrate the span via the binary inputs by taking the following steps.
Presettings
1.
Choose the measuring range to be calibrated. This is dependent on the setting of the
"Total range calibration" in function 23:
–
Total range calibration activated:
Select the desired measuring range in function 22 as the leading measuring range.
– Total range calibration deactivated:
Set the desired measuring range as the current measuring range. This is done using
one of the following:
- Menu 40
- Binary input with the "Measuring range x" function in function 72.
2. Configure a relay output with "Calibration gas x" for controlling the corresponding
calibration gas valve (function 71). The number of this calibration gas must correspond to
the number of the measuring range to be calibrated.
3. Assign a binary input with the "Calibration gas" function (function 72).
4. Assign a binary input with the "Span Calib." function for calibrating the span.
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 range switching). This step is necessary because the device otherwise
remains in the measuring range being calibrated.
6. Exit function 72 and accept the changes.
Perform calibration
1.
Set 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 with "Calibration gas" can only be effectively controlled in
"Measuring" operating state! Therefore, make sure that the device is in "Measuring" state.
2. Now set the "Calibration gas" binary input with the necessary voltage for at least
1 second.
For FIDAMAT 6-E: The corresponding relay is energized by the binary input and now
opens the calibration gas valve.
For FIDAMAT 6-G: The corresponding relay is energized by the binary input and now
opens the calibration gas valve and closes the sample gas valve.
At the same time, the device switches over to "Calibrating" state (shown in the measured
value display with "■ CAL") and activates the "Function control" (shown in the measured
value display with "■ CTRL").
3. Wait until the measured value has stabilized.
