General Safety Information
This Meter complies with the IEC61010 standard for pollution degree 2, overvoltage category (CAT
III 1000V, CAT IV 600V), and double insulation.
Use the Meter only as specified in this operating manual, otherwise the protection provided by the
Meter may be impaired.
In this manual, a Warning identifies conditions and actions that pose hazards to the user, or may
damage the Meter or the equipment under test. A Note identifies general safety information that the
user must observe.
Rules for Safe Operation
Warning
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to
the equipment under test, adhere to the following rules:
Before using the Meter inspect the meter housing. Do not use the Meter if the housing is
damaged, open, or removed. Look for cracks or missing plastic. Pay particular attention to the
insulation around the connectors.
Inspect the test leads for damaged insulation or exposed metal. Replace damaged test leads
(identical model number or electrical specifications) before using Meter.
Do not apply more than the rated voltage as specified on the Meter.
When measurements have been completed, disconnect the connection between the test
leads and the circuit under test, remove the testing leads from the input terminals of the Meter
and turn the Meter power off.
To avoid electrical shock, do not attempt measurements while the Meter’s housing and / or
battery door is opened.
When the effective voltage exceeds 30VAC, special care should be taken while measuring as
a shock hazard exists at this voltage level.
Use the proper terminals and functions for the measurement in question.
Do not use or store the Meter in an environment of high temperature, humidity, explosive,
inflammable or one with a strong magnetic field.
Do not use the Meter if the meter is wet or if the user’s hands are wet.
When using the test leads, keep fingers behind the finger guards.
Replace the battery as soon as the battery indicator appears. With a low battery, the Meter
may produce false readings that can mislead the user and cause electric shock and personal
injury.
When opening the battery door, ensure that the Meter power is OFF.
When servicing the Meter, use only the same model number or identical electrical
specifications when acquiring replacement parts.
The internal circuit of the Meter must not be tampered with. Tampering with the internal
circuitry can cause meter damage and personal injury.
A soft cloth and a mild detergent should be used to clean the surface of the Meter when
servicing. Do not use abrasives or solvents when cleaning the meter; doing so can cause
corrosion, damage and can potentially compromise the meter’s safety features.
The Meter is suitable for indoor use only.
Turn the Meter off when it is not in use and remove the battery when the meter is to be stored
or unused for long periods.
Keep track of the battery age and replace batteries when necessary. Leaking batteries can
damage the meter.
