AUTOCAL/ Check cycle parameters
Figure 5-19 Autocal / Check cycle parameters
With this subfunction, you can parameterize various time constants for activating a cyclically
repeating Autocal sequence.
"Time from Autocal to Autocal (cycle time)":
Every setting between 0 and 500 (hours) is accepted by the device. "0" corresponds to no
Autocal cycle.
"Time to first Autocal" (after the time of setting):
If you enter a "0" here and Autocal is activated with
"Autocal on/off", the device begins
immediately with the Autocal sequence.
If Autocal is switched off, the device only starts an Autocal sequence if Autocal is switched
on within one minute after entering "0". If not, the total time between two Autocal cycles goes
by starting with 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 reset to the current time with function 58.
"Calibrate test gas at every xth cycle":
Here you set the number of cycles after which the test gas should be calibrated.
If you would like to save on test gas, for example, and not calibrate span along with every
zero calibration, enter an integer value > 1 in the line
Calibrate test gas at every :: cycle.
Note
As long as Autocal is activated (Autocal ■), access to functions 20 and 21 is blocked. If you
activate these functions anyway, a corresponding message appears on the display.
