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
specications 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 away 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 any 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 600V between the two Meter’s input terminal to avoid electric
shock and damages to 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.
- Do not use or store the Meter in an environment of high temperature, humidity, explosive,
inammable and strong magnetic eld. The performance of the Meter may deteriorate after
dampened.
- When using the test leads, keep your ngers behind the nger 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
specications replacement parts.
- When servicing the Meter, use only the same model number or identical electrical
specications 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.
