The measuring- and display range values read back from the interface are always in the
selected measurement unit!
When using the interface, the auto-range-function should be turned off. If auto-range is
activated, the returned value ar based on the resolution of the smallest ranges, there
may be returned extreme values like 123400.0 µS/cm instead 123.4 mS/cm.

If "bAt" is flashing the battery will be exhausted soon. Further measurements are possible for short time. If
"bAt" is displayed continuously the battery is ultimately exhausted and has to be replaced. Further
measurements aren't possible any more.

What to do?
Replace battery
Check power supply, replace it if necessary
Disconnect battery and power supply, wait shortly,
then reconnect
Return to manufacturer for repair
Check: pressure not within sensor range?
-> measuring value to high!
Return to manufacturer for repair
Check: pressure not within sensor range?
-> measuring value to low!
Return to manufacturer for repair
