PRECAUTIONS FOR USE
These current probes comply with safety standards EN 61010-1, EN 61010-031,
and EN 61010-2-032 for voltages of 300V in Category IV or 600V Category III.
The protection obtained by the instrument can be compromised if it is used in a
way that is not recommended by the manufacturer.
■The operator and/or the responsible personnel must carefully read and clearly
understand the various precautions to be taken in use. Sound knowledge
and a keen awareness of electrical hazards are essential when using this
instrument.
■Do not use the clamp on networks at higher voltages or in higher categories
than those mentioned.
■Do not use the clamp if it appears to be damaged or incorrectly closed.
■Before each use, check the condition of the insulation on the leads and
housing. Any item of which the insulation is deteriorated (even partially) must
be set aside for repair or scrapping.
■ Always keep your ngers behind the physical safety guard.
■All troubleshooting and metrological checks must be performed by competent
and accredited personnel.

■Set the switch to the position to check the battery status. If the battery
indicator lights, the battery must be replaced (see §5.3).
■Set the switch to ON. The indicator lights.
■Connect the current probe to one of
the current inputs on the device.
■Turn the device ON.
■Adjust the zero by watching the
display of the device and turning the
zero adjustment knob until the device
displays 0.
■Open the jaws and clamp the
conductor carrying the current to be

5. MAINTENANCE
Use only factory specied replacement parts. AEMC®will not be held responsible
for any accident, incident, or malfunction following a repair done other than by its
service center or by an approved repair center.
5.1 Warning
■To ensure optimum performance, it is important to keep the probe jaw mating
surfaces clean at all times. Failure to do so may result in error in readings.
■To avoid electrical shock, do not attempt to perform any servicing unless you
are qualied to do so.
■Do not perform any service while the current probe is on any circuit.
■To avoid electrical shock and/or damage to the instrument, do not get water or
other foreign agents into the electronic module.
5.2 Cleaning
Disconnect the instrument from any source of electricity.
■Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and
immediately dry with a dry cloth.
■Do not use alcohol, solvents, or hydrocarbons.
■Do not splash water directly on the instrument.

14 AC/DC Current Probe Model J93
5.3 Battery Replacement
Disconnect the instrument from any source of electricity.
To replace the battery, proceed as follows:
■Insert a tool, not more than 3mm in diameter, in the hole in the battery com-
partment cover.
■Push to unlock the battery compartment cover, then slide it off.
■Remove it completely by hand.
■Remove the battery and the shim from the compartment.
■Place the new battery in the compartment with the polarity as indicated on the
label. Then replace the shim.
■Put the battery compartment cover back in the slide and push it in until you
hear a click.
Used batteries must not be treated as ordinary household waste. Recycle
them appropriately.
