QUEStionable status register (PCR-LE/PCR-LE2)

The QUEStionable status register is a 16-bit register that stores information related to the questionable events and status during PCR operation.

These register bits may indicate problems with the measured data of the PCR.


Bit Bit weight Bit name Description
0 1 OV(Over Voltage Protection) Overvoltage protection has been activated
1 2 OC(Over Current Protection) Overcurrent protection has been activated
2 4 PU Device error has occurred
3 8 UV(Under Voltage Protection) Undervoltage protection has been activated
4 16 OHP(Over Heat Protection) Overtemperature protection has been activated
5 32 SHUT DOWN Shut down the output
6 64 OCP2 Overcurrent internal semiconductor protection has been activated
7 128 NOT USED --
8 256 CAL(CALibration) Calibration data is invalid
9 512 OP(Over Power protection) Overpower protection has been activated
10 1024 CL-PEAK Current limit control has been activated
11 2048 Not Used --
12 4096 CL-RMS(Current Limit on RMS) TRIP ENABLE: During overload judgment
TRIP DISABL: During output voltage control
