To avoid electric shock:
• Use caution during installation and use of this product; high
voltages and currents may be present in circuit under test.
• This product must be used only by qualified personnel
practising applicable safety precautions.
• Do not use product if damaged.
• Always connect probe to display device before it is installed
around the conductor.
• Always ensure the probe is removed from any live electrical
circuit, and leads are disconnected before removing the
battery cover.
• Do not hold the probe anywhere beyond the tactile barrier

INTRODUCTION
The CP 30 / CP 35 current probe have been designed for use
with multimeters and oscilloscopes respectively for accurate,
non-intrusive measurement of AC,
DC
waveform currents.
Using advanced Hall Effect technology the CP 30 / CP 35 can
measure currents accurately with a resolution of 1mA from
5mA to 30 Amps over the frequency range of DC to 100 kHz.
These features make it a powerful tool for use in inverters,
switch mode power supplies, industrial controllers and other
applications requiring current measurement and/or waveform
analysis.
