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 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.
• The rotary switch should be placed in the right position and no any
changeover of range shall be made during measurement is conducted to
prevent damage of the Meter.
• When the Meter 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.
•
If the value to be measured is unknown, use the maximum measurement position.
• 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 highvoltage capacitors before
testing resistance, continuity, diodes.
• Before measuring current, check the Meter’s fuses and turn off power to the
circuit before connecting the Meter to the circuit.
• 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.
• 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 using for some
time, replace the battery as soon as leaking appears. A leaking battery will
damage the Meter.
