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
see Fig 1.
INTRODUCTION
The CP 2005 current probe has been designed for use with
multimeters and oscilloscopes respectively for accurate, non-
intrusive measurement of AC, DC and complex waveform
currents.
Using advanced Hall Effect technology the CP 2005 can
measure currents accurately up to 2000 Amps RMS over the
frequency range of DC to 20 kHz.
These features make it a powerful tool for use with inverters,
switch mode power supplies, industrial controllers and other
applications requiring current measurement and/or waveform
analysis.
OPERATING INSTRUCTIONS
Switch On
When the probe is switched on to the required measuring
range, the green LED will illuminate. The LED starts flashing
when the battery voltage is too low for normal operation and
warns the user that it requires changing.
Auto Zero
The output zero offset voltage of the probe may change due
to thermal shifts and other environmental conditions. Select
the required measuring range and to null the output voltage
depress the Auto Zero button. Ensure that the probe is away
from the current carrying conductor whilst the probe is being
nulled.
Current Measurement
Switch on the probe by selecting the required measuring
range and check that the green LED is lit. Connect the output
lead to an oscilloscope, multimeter or other measuring
equipment. Zero the probe using the Auto Zero button. Clamp
the jaws of the probe round the conductor ensuring a good
contact between the closing faces of the jaws. Observe and
take measurements as required. Positive output indicates
that the current flow is in the direction shown by the arrow on
the probe.
Auto Power OFF
In order to save battery life, the probe will automatically
switch itself off after approximately 10 minutes. To disable
the Auto power off function, Switch Off the probe and Switch
On whilst pressing the auto zero button. The red LED will
illuminate and the probe will stay on until switched off again.
Battery Replacement
The green or red LED will flash when the minimum operating
voltage is approached. Refer to Fig.1. Use the following
procedure: Unclamp the probe from the conductor, turn it off
using the On - Off switch and disconnect the output leads,
from external equipment. Loosen the captive screw which
secures the battery cover. Lift the cover through 30° and pull
it clear of the probe body as shown in Fig 1. Replace the
battery and re-fit the battery cover and fasten the screw.
Fit only Type 9 V PP3 Alkaline (MN 1604).
SAFETY WARNING
Before removing the battery cover, make sure that
the probe is remote from any live electrical circuit
