•
High range (100 mV/A) is selected and the corresponding LED lights up.
The Probe is now ready to measure current.
Note
Do not operate the Probe during the activation sequence.
Current Measurement
To measure current, clamp the Probe around the current carrying conductor
and use the slide to ensure that the Probe head is locked (see Figure 3).
A positive output is obtained when the current flows in the direction of the
arrow on the Probe head.

Caution
The performance of the Probe deteriorates if there is
mechanical stress within the aperture, hindering the
correct closing of the measuring head.
Note
If a 50
Ω
load is used, the amplitude of the output signal is halved,
and the specifications are no longer guaranteed.
Range Selection
Two ranges are available by pressing the RANGE
button:
1.
High range (100 mV/A): oscilloscope 1 M
Ω
measurement up to 30 A
continuous and 50 A pk (< 10s).
2.
Low range (1 V/A): oscilloscope 1 M
Ω
measurement up to 3 A max.
