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. |
