Device variable value
Device variable status
Meaning of "Quality" (bit 6 and 7):
3: Good - device variable value with
normal accuracy.
2: Poor - device variable value with
low accuracy.
1: Manual/Fixed - fixed device vari-
able value.
0: Bad - there may be a device vari-
able value, but the device variable
value may not be used.

Troubleshooting
Remedy
Performing zero adjustment.
Performing zero adjustment.
Change battery pack soon.
Change battery pack immediately.
Check voltage.
Check voltage.
In case of high temperatures due to
solar radiation, use weather protec-
tion set (accessory).
In case of low temperatures, pay
attention to operating temperature.
Exit maintenance mode.
Exit simulation mode via PolySoft.
