INTRODUCTION
The PR200 and the PR1001 current probes have been
designed for use with digital multimeters, recorders and
other
suitable
equipment
for accurate
non-intrusive
measurement
of AC,
DC
and
complex
waveform
currents.
Using advanced Hall Effect technology the PR200 can
accurately measure currents up to 200 A r.m.s. over the
frequency range of DC to 10 kHz,
while the PR1001
measures currents up to 1000A DC or AC peak.
These
features make them powerful tools for use in inverters,
switch
mode
power
supplies,
industrial
controllers,
automotive diagnostics and other applications requiring
accurate isolated current measurement.

OPERATING
INSTRUCTIONS
Refer to Fig. 1 for the PR200 and Fig. 2 for the PR1001.
3.1
Switch On
When
the probe
is switched
on the red LED
will
illuminate. If the LED starts flashing this warns the user
that the battery voltage is too low for normal operation
and that it should be changed as described in section 5.
3.2
Zero Adjustment
The output zero offset voltage of the probe may change
due
to
thermal
shifts
and
other
environmental
conditions.
To adjust the output voltage to zero depress
the thumbwheel and rotate.
Ensure that the probe is
away from the current carrying conductor whilst the
adjustment is made.
3.3
Current
Measurement
Switch on the probe using the On - Off switch and
check that the LED
is lit.
Select the required current
range ( 20 Amp or 200 Amp - PR200 or 200A or 1000A -
PR1001).
