Before using the Meter, inspect the case. Do not use the Meter if it is damaged or the case (or part of the
case) is removed. Look for cracks or missing plastic. Pay attention to the insulation around the connectors.
Inspect the test leads for damaged insulation or exposed metal. Replace damaged test leads with identical
model number or electrical specifications before using the Meter.
Do not apply more than the rated voltage, as marked on the Meter.
When your measurements have been completed, disconnect the connection between the test leads and
the circuit under test, remove the test leads from the input terminals of the Meter and turn the Meter
power off.
Do not carry out the measurement when the Meter’s back case and / or battery door is opened to avoid
electric shock.
When the Meter is operating at an effective voltage over 30V in AC, special care should be taken.
Use the proper terminals and function for your measurements.
Do not use or store the Meter in an environment of high temperature, humidity, explosive, flammable
and strong magnetic field. The performance of the Meter may deteriorate if damp or wet.
Do not use the Meter if its surface is wet or the user’s hands are wet.
When using the test leads, keep your fingers behind the finger guards.
Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might
produce false readings that can lead to electric shock and personal injury.
