conductors.

Amps AC Measurement with Jaw

To measure amps ac:

1. Turn control knob to

2. Position the Clamp jaw around the conductor.

The display shows the amps ac measurement and frequency and also shows C to indicate

that the measurement is from the jaw.

Amps AC Measurement with iFlex Probe

The high-performance AC Flexible Current Probe uses the Rogowski principle for accurate, non-

intrusive measurement of sinusoidal, pulsed, and other complex waveforms. The flexible and

lightweight measuring head allows quick and easy installation in hard-to-reach areas and works

well with large conductors.

To use the iFlex Probe:

1. Connect the iFlex Probe to the Clamp. See Figure 2.

2. Connect the flexible part of the iFlex Probe around the conductor. If you open the end of the

iFlex Probe to make the connection, make sure that you close and latch the coupling. See the

detail in Figure 2. You should be able to hear and feel the lock snap into place.

Note

When you measure current, center the conductor in the iFlex Probe. Avoid

measurements close to other current-carrying conductors.

3. Keep the probe coupling >2.5 cm (1 inch) away from the conductor.

4. Turn the control knob to

5. Push .

The display shows J to indicate that the measurements are from the iFlex Probe. When the

current measurement is <0.5 A, the center dot in the icon flashes. For current measurements

>0.5 A, the center dot is steady.

The display shows the measurement.
