The status messages serve to inform and alert the user of the instrument
operation. Among these features are the operating status, warning status and
error messages.
The status message can be reviewed in the Main Menu and through the
internal memory data download. In case there is no status message present,
the measuring instrument is in the normal operation mode and the green
LED "READY" will be illuminated.
The yellow LED "STATUS" stands for an operating and/or warning status.
The red LED "ERROR" will illuminate in case of an instrument error.
The general status message is abbreviated and represented as a 6-digit
hexadecimal number. Each of the 6 characters represents up to 4
independent conditions. The eight global error status bits each represent a
group of eight status bits. Consequently, a total number of 64 errors
independent of each other can be distinguished allowing the user to pin
point a specific error.
With the measuring instrument being in the normal error-free
measurement operation, the status will show the value 000000.
Global status: 6 characters, each one consisting of 4 bits, characters 0
thorough F.
In the following section is a list of the most important status displays. The
status, however, can occur also in various other combinations.
