Rules For Safe Operation - Rev Ritter Em402 Bedienungsanleitung

RULES FOR SAFE OPERATION
• 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. Check the test leads for
continuity. 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, between the terminals or
between any terminal and grounding. If the value
to be measured is unknown, use the maximum
measurement position and reduce the range step
by step until a satisfactory reading is obtained.
• When measurement has 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.
• The rotary switch should be placed in the right
position and no changeover of range shall
be made during measurement is conducted to
prevent damage of the Meter.
• Do not carry out the measurement when the
Meter's back case and battery compartment are
not closed to avoid electric shock.
• Do not input higher than 250V between the Meter's
terminals and the grounding to avoid electric
shock and damages to the Meter.
• When the Meter is working at an effective voltage
over 60V in DC or 30V rms in AC, special care
should be taken for there is danger of electric
shock.
• Use the proper terminals, function and range
for your measurements.

• Do not use or store the Meter in an environment
of high temperature, humidity, explosive,
inflammable and strong magnetic field. The
performance of the Meter may deteriorate after
dampened.
• When using the test leads, keep your fingers
behind the finger guards.
• Disconnect circuit power and discharge all high
-voltage capacitors before testing resistance,
continuity and diode.
• 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.
• When servicing the Meter, use only the same
model number or identical electrical specifications
replacement parts.
• The internal circuit of the Meter shall not be altered
at will to avoid damage of the Meter and any
accident.
• Soft cloth and mild detergent should be used to
clean the surface of the Meter when servicing.
No abrasive and solvent should be used to
prevent the surface of the Meter from corrosion,
damage and accident.
• The Meter is suitable for indoor use only.
• Turn the Meter off when it is not in use and take
out the battery when not using for a long time.
• Constantly check the battery as it may leak when
it has been in use for some time, replace the
battery as soon as leaking appears. A leaking
battery will damage the Meter.
