3.2 CAL Switch
The CAL switch is used to protect the calibration data / parameters from unauthorized access.
If the CAL switch is in the position 'open', the calibration data and parameters can be altered via the
PC program or via the Profibus connection.
If the CAL switch is in the position 'locked', the calibration data (e.g. deadload, span) and the
calibration parameters (e.g. measure time, zerotracking etc.) cannot be altered.
For 'legal for trade' (W&M) applications the CAL switch has to be closed and the cover has to be
sealed.
3.2.1 Factory settings
Calibration data <default> Calibration parameters <default>
Full scale (FSD) <3000> <Kg> Measuring time (M) <320>ms
Step width <1> Measuring rate <160>ms
Deadload <0.000000>mV/V Standstill time <1>M
Span <1.000000>mV/V Standstill range <1.00>d
Standstill timeout <8>M
Calibration parameters <default>
Testmode <absolute>
Overload (range above FSD) <9>d Zeroset range <50.00>d
* W&M mode <off> Zerotrack range <0.25>d
Filter <off> Zerotrack step <0.25>d
Frequency <1.56 Hz> Zerotrack repeat <0>M
* The W&M parameter has to be set to 'on' or 'off' before entering calibration data, see chapter 4.7.2.5.
At delivery the calibration data and parameters are set to default (factory settings).
If a new calibration is started, the calibration data are set to default (The parameters remain
unchanged).
Calibration data and parameters are stored in EAROM and kept in case of power failure or if the
instrument is disconnected from power supply.
