Warning
Maintenance
These safety warnings are provided to ensure the safety of
personnel and proper operation of the instrument.
· Read the instruction manual completely and follow all the safety
information before attempting to use or service this instrument.
· Wear protective clothing and gloves as required.
· Use caution on any circuit: potentially high voltages and currents
may be present and may pose a shock hazard.
· Read the Safety Specifications section prior to using the current
probe. Never exceed the maximum voltage ratings given.
· Safety is the responsibility of the operator. The Flexible AC
Current Probe must be used only by qualified personnel using
applicable safety precautions.
· ALWAYS de-energize the circuit before wrapping the Flexible
AC Current Probe around bare conductors, bus bars, or near live
parts. Do not wrap on live conductors.
· ALWAYS connect the electronic module to the display device
before wrapping the Flexible AC Current Probe around the
sample being tested.
· ALWAYS inspect the module, sensor, sensor cable, and output
terminals prior to use. Replace any defective parts immediately.
Use only factory parts.
· NEVER use the Flexible AC Current Probe on electrical
conductors rated above 1000 V in overvoltage category III.
War ni ng
· For maintenance use only specified replacement parts.
· Avoid electrical shock: do not attempt to perform any servicing
unless you are qualified to do so.
· Do not perform any service while the Flexible AC Current Probe is
on any circuit.
· Avoid electrical shock and/or damage to the instrument: do not get
water or other foreign agents into the electronic module.
· Also see warning on page 2.
Bat tery Repl acement
· If the power ON indicator (green LED) blinks or does not light up,
replace the battery.
· Remove the Flexible AC Current Probe from any circuit before
replacing the battery.
· To replace the battery, open rear case, replace battery and
reassemble. The green LED should go on when the module is
turned on.
Cleaning
· It is important to keep the probe sensor latch mating surfaces
clean and prevent foreign bodies from hampering the closing. The
sensor may be gently cleaned with a soft cloth, soap and water.
Dry immediately after cleaning. Avoid water penetration into the
electronic module.
· Make sure the sensor, electronic module, and all leads are dry
before any further use.
