PRECAUTIONS BEFORE USE
The protection assured by the current probe can be compromised if it is used in a
way that is not recommended by the manufacturer.
■Comply with the rated maximum voltage and current, and the measurement
category. Do not use the current probe on networks where the voltage or
category exceeds those specied.
■Comply with the conditions of use (e.g. temperature, humidity, altitude, degree
of pollution, location).
■Do not use the current probe if its housing is open, deteriorated, or incorrectly
reassembled. Before each use, check the integrity of the insulation of the unit,
jaws, clamps, housing, and leads.
■Do not subject the current probe to water or other liquids.
■Keep the jaw contacts of the clamp absolutely clean.
■Use suitable personal protective equipment when hazardous voltages may be
accessible in the installation where the measurement is made.
■Any repairs must be carried out by accredited skilled personnel.

3. OPERATION
The current probes and exible sensors are used to measure the current owing
in a conductor or bus bar without opening the circuit. They also insulate the user
from dangerous voltages in the circuit.
The choice of current probe or sensor to be used depends on the amperage to be
measured and the diameter of the cables or size of the bus bar.
■For three-phase measurements, use the color-coded ID markers to associate
a color for each current input to match the phase identiers on the measured
system.
IMPORTANT NOTE: Always connect the probes or sensors
with the indicating arrows pointing toward the load.
For Example Only (instrument’s will vary):
■Connect the current probe or sensor to the current terminals of the instrument.
For MR193-BK and SL261 Probes:
■MR193-BK: Set the switch to 1 mV/A; the ON indicator will light up.
SL261: Set the switch to 10 mV or 100 mV/A; the ON indicator will light up.
■Connect the probe to the instrument.
■Adjust the zero by turning the potentiometer with no conductor in the jaws of the
clamp.
■When the measurement is nished, turn the probe switch to OFF.

14 Current Probes & Sensors for Power Quality Meters and Power Energy Loggers
For Probes:
■Press the jaw opening lever on the probe to open the jaws.
■Clamp the probe around the conductor to be tested. For best results, center the
conductor in the jaws of the clamp.
I
For AmpFlex® and MiniFlex® Sensors:
■AmpFlex®: Press simultaneously on both sides of the opening connector.
■MiniFlex®: Press the opening device to open the exible sensor.
■Clamp the sensor around the conductor to be tested. For best results, center the
conductor in the jaws of the clamp.
■Close the sensor by pushing the moving part into the connector until it clicks.
NOTE: For details of the measurement configuration and technical specifications,
refer to the user manual of the instrument the current probe is being used with.
