Operating Instructions, 01/2019, A5E00222135-04
If AUTOCAL is deactivated, the device only starts an AUTOCAL sequence if AUTOCAL is
activated within one minute after entering "0". If not, the total time between two AUTOCAL
cycles elapses starting from the input of "0".
Note
The clock inside the device also runs when AUTOCAL is deactivated! It starts the first time
the device is switched on and must be set to the current time using function 58.
"Carry out span calibration for each xth cycle":
Here you set the number of cycles after which a calibration with the calibration gas is to be
carried out.
If you would like to save on calibration gas, for example, and not calibrate the span along
with every zero calibration, enter in the line
"Carry out scan calibration gas for each xth:
cycle"
an integer value > 1.
Note
As long as AUTOCAL is activated (A
utocal ■), access to functions 20 and 21 is blocked. If
you activate these functions anyway, a corresponding message appears on the display.
Settings for AUTOCAL check
Figure 8-15 Autocal check
In the
"Autocal check"
subfunction, enter the desired calibration tolerances that are to be
checked by AUTOCAL check. Using functions 71 and 72, you can also select the relay
output or binary input for "AUTOCAL Check".
When a calibration limit is exceeded, the maintenance request W10 is set, and also, if
configured, the relay "Acal Chk Dif".
Both will be reset again after an error-free AUTOCAL Check. W10 is retained in the logbook.
