6.2.3.1 Software Version
6.2.3.2 Update Software

Function: Displays detailed hard- and software version information
Displays: Hardware
The revision code of the main PCB.
SW Ver.
The creation date of the system software.
Masterboard
The version code of the system software.
Display Board
The version code of an external Control and Display unit, if present.
If no external unit is connected, dashes are shown.
Function: Sets the correction values for the on-board temperature and gyro-
sphere current measurement
Settings: Corr. Val. Temp.
Temperature correction value. Adjusts the measured value to show
the gyrosphere ambient temperature.
Correction range is -99.9 – +99.9 °C.
Gyro Current Gain
Gain factor for the gyrosphere current. Adjusts the measured value
to show the current flowing through the gyrosphere.
Correction range is 0.000 – 9.999, where a setting of 1.000 equals
unity gain, i.e. no correction.
Note
The correction values are set in the factory. These must not normally be altered.
However, when the system software is exchanged, the values will be lost and
must be re-entered manually.
The correction values are specific to the respective main PCB.
