Effective measurement range of power quality analyzer
QThe voltage range of the PQ3198 is 600V only. Is it possible to measure a 690V circuit?
Yes, you can measure 690V.
Although the PQ3198 is defined as having a "600V range" to align with international standards for delineating voltage categories, the effective measurement range (with guaranteed accuracy) is "130% of range", so you can accurately measure from 10 to 780V (130% of 600V).
The effective measurement range of each function on the PQ3198 are:
- Voltage: 10 to 780V AC, 1 to 600V DC
- Current: 1% to 120% of range
- Power: 0.15% to 130% of range (both voltage and current are within the effective measurement range.)
- Harmonics: Specified separately (Please refer to the instruction manual.)
For your reference, the PQ3100 Power Quality has a "1000V range" with an effective measurement range from 10V to 1000V AC as well as from 5V to 1000V DC.
