30 Operation
6.5 Starting/stopping the measurement
Starting
 Device in S TANDBY
► Start measurement.
 Device switched to M
EASURE state.
Stopping
 Unit measures
► Stop measurement.
 Device switches to S
TANDBY state.
6.6 Loading and storing parameters
You can use a USB stick to backup and restore the control unit and mass
spectrometer module parameters.
► Load parameters as needed:
F UNCTIONS > D ATA > P ARAMETER > L OAD > L OAD PARAMETER
► Save parameters as needed:
F UNCTIONS > D ATA > P ARAMETER > S AVE > S AVE PARAMETER
6.7 Select operation mode
V AC = Vacuum mode
S NIFF = Sniff mode
► Select operation mode as needed:
S ETTINGS > S ET UP > O PERATION MODES > V AC /S NIFF > O PERATION MODE
During the measurement During standby
Z ERO is possible. Z ERO is not possible.
The trigger outputs switch depending on
the leakage rate and the trigger threshold.
The output at the trigger outputs is:
Leakage rate value exceeded
threshold.
Sniff is possible. Sniff is not possible.
Calibration using PLC input or output will
start an external calibration. Calibration using PLC input and output
will start an internal calibration.
