�

DANGER! - identifies conditions and actions that pose hazard(s) to the user

�

WARNING! - identifies avoiding electric shock.

�

CAUTION! - identifies conditions and actions that may damage the Meter and carrying out accurate measurement.

�

DANGER!

Use of instrument in a manual not specifed by the manufactuer may impair safety features/ protection provided by the equipment. Read the following safety information carefully before using or servicing the instrument.

• Do not apply more than 600V.

• Do not use the Meter around explosive gas,vapor or dust.

• Do not use the Meter in a wet environment.

• When using the test leads, keep your figures away from the lead contacts. Keep your figures behind the finger guards on the leads.

• Do not use the Meter with any parts or cover removed.

• When carrying out insulation measurement, do not contact the circuit under test.

�

WARNING!

• Do not use the Meter if it is damaged or metal part is exposed. Look for cracks or missing plastic.

• Be careful when working above 33V rms, 46.7V ac rms or 70V DC. Such voltages pose a shock hazard.

• Discharge all loading of circuit under test after measuring high voltage.

• Do not change battery when the Meter is in wet environment.

• Place test leads in proper input terminals. Make sure all the test leads are firmly connected to the Meterís input terminals.

• Make sure the Meter is turned off when opening the battery compartment.

�

CAUTION!

• When performing resistance tests, remove all power from the circuit to be measured and discharge all the power.

• When servicing the Meter, use only the same model number or identical electrical specifications of test leads and power adaptor.

• Do not use the Meter if the battery indicator ( ) shows a battery empty condition. Take the battery out from the Meter if it is not used for a long time.

• 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.

• 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.

• Dry the Meter before storing if it is wet
