QUEStionable status register

The QUEStionable status register is a 16-bit register that stores information related to the questionable events and status during KPM1000 operation.These register bits may indicate problems with the measured data of the KPM1000.

 

Bit Bit weight Bit name Description
0 1 Integ Overflow An overflow has occurred in the integrated power, integrated current, or integration time.
1 2 Freq Out of range The frequency is outside of the measurable range (10 Hz to 10 kHz).
2 4 Cannot Calc PF Because the voltage or current is less than or equal to the mute level, the power factor and phase angle cannot be calculated.
3 8 Over Irms The current rms range has been exceeded.
4 16 Over Vrms The voltage rms range has been exceeded.
5 32 Wh Over Occurred The voltage or current range has been exceeded during integrated measurement.
6 64 Ah Over Occurred The current range has been exceeded during integrated measurement.
7 128 NOT USED Not used.
8 256 NOT USED Not used.
9 512 NOT USED Not used.
10 1024 NOT USED Not used.
11 2048 Internal Com Error An internal communication error has occurred.
12 4096 Over Ipeak A current peak over-range has occurred.
13 8192 Over Vpeak A voltage peak over-range has occurred.
14 16384 Sync Error A synchronization error has occurred.
15 32768 NOT USED Always 0.
