Note:
1. The null-position cross phase difference between current and voltage waveforms is positive
if current lags behind voltage; negative if current is ahead of voltage.
2. An error of 2° is added if the measured conductor is not placed at the center of the clamp jaws.

Note:
1) Minimum measured voltage is 30V, minimum measured current: >10% of current range.
2) THD-F and THD-R are displayed on the LCD.
3) Harmonic analysis is recorded in the clamp, and can be displayed and viewed on mobile
APP via Bluetooth module.
4) If fundamental frequency is 100Hz, the harmonic order reaches 40.
If fundamental frequency is >100Hz, the harmonic order reaches 15.
