KEW3128 1. Safety Warnings
# DANGER
● Put a pair of insulated gloves and use this instrument.
● Never make measurement on a circuit in which the electrical potential
exceeds AC/DC600V.
● Do not attempt to make measurement in the presence of flammable
gasses. Otherwise, the use of the instrument may cause sparking, which
can lead to an explosion.
● Never attempt to use the instrument if its surface or your hand are wet.
● Be careful not to short-circuit the power line with the metal part of the test
leads when measuring voltage. It may cause personal injury.
● Do not exceed the maximum allowable input of any measuring range.
● Do not press the Test Button with test leads connected to the instrument.
● Never open the Battery Compartment Cover while making measurement.
● Do not touch the circuit under test when measuring insulation resistance or
right after a measurement. You may get an electric shock by a test voltage.
● Stop a measurement if contamination or carbonization which may impair
insulation characteristics is found on the test leads or around the terminals.
● Do not repeat short-circuiting/ opening of test leads intentionally during
insulation resistance measurements. Otherwise, measurements may be
ceased or LCD may become blank due to a malfunction of the instrument.
Aerial discharges occur at the tips of test leads when short-circuiting and
opening the test leads; excessive discharges may impair the performance
of the instrument.
# WARNIG
● Never attempt to make any measurement if any abnormal conditions are
noted, such as broken case and exposed metal parts.
● Do not rotate the Range Switch with the test leads connected to the equipment
under test.
● Do not install substitute parts or make any modification to the instrument. Return
the instrument to Kyoritsu or your distributor for repair or re-calibration.
● Do not try to replace battery if the surface of the instrument is wet.
● Be sure to insert the plug into the terminal firmly when using test leads.
● Make sure to power off the instrument when opening the Battery Compartment
Cover for battery replacement.
