The R&S HMC8015 power analyzer datasheet and technical data list:
Range configuration
CF3 Peak
voltage 600 V ±1800 V
current 100 mA ±300 mA
Measurement accuracy (±reading in % ±peak range in %)
Frequency ActivePower
45Hz < f < 66Hz 0.05 + 0.05
voltage, current: F = frequency in kHz
Additional errors
Power factor < 1 | ±(0.2 + 0.2 *F)%, only for active power
Does this mean that when range is set to 600 V, 100 mA and measuring these values:
- Urms = 229.96 V
- f = 49.986 Hz
- Irms = 15.33 mA (with peaks to 230mA)
- P = 0.064 W
- Q = 3.525 var
- Lambda = 0.018
That the measurement accuracy for active power can be calculated as follows:
- 0.05% for reading + 0.2% for power factor < 1 = 0.25% of reading
plus
- 0.05% for peak range + 0.2*F for power factor < 1 = 0.05 + 0.2 * 0.049986 ≅ 0.06% of peak value for range
resulting in a nett measurement accuracy of:
- 0.06% of 0.064 W = 0.0000384 W
plus
- 1800 V x 0.3 A = 600 * 0.06% = 0.36 W
totalling to ≅ ±0.36 W of measurement accuracy?
