Figure 5-20 Autocal/Check cycle parameters
With this subfunction, you can parameterize various time constants for activating a cyclically
repeated Autocal sequence.
"Time from Autocal to Autocal (cycle time)":
Any 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 "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
passes by, starting with the input of "0".
Note
The clock inside the device also runs when Autocal is deactivated! It restarts when 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
"Calibrate with calibration gas at every : : cycle"
an integer > 1.
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.
