02 / TRMS · VFD · INRUSH

Read the signal. Capture the inrush.

The 400 Hz VFD low-pass filter, 100 ms InRush measurement and MAX/MIN and REL functions help observe electrical behaviour. HOLD keeps the reading on screen.

TRMS

True RMS AC voltage and current measurement.

InRush · 100 ms

Capture starting current.

VFD / LPF

Low-pass filter with a 400 Hz cut-off frequency.

6000 counts

2-inch LCD, backlight and bargraph.

03 / Optional accessory / FLEXC128

Open up the range. Up to 3000 A AC.

The flexible Rogowski sensor connects to the C128PRO CAT III inputs: current and frequency appear directly on the display. Three selectable ranges: 30, 300 and 3000 A AC.
