Page 2: Safety Information
INTRODUCTION This meter is a compact 3 ½ digit, digital multimeter, designed to measure DC and AC voltage, DC and AC current, resistance, diode, continuity and battery. Some models also have temperature measurement function, frequency measurement function, non-contact AC voltage detection function, or live ac wire detection function This multimeter features backlight, data hold, full-range overload protection, illumination function, etc It is an easy to operate, useful testing tool. - Page 3 follow these guidelines: Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors. Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before you use the meter.
- Page 4 When using the probes, keep your fingers behind the finger guards on the probes. Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the live test lead first. Remove the test leads from the meter before you open the battery cover or the case.
- Page 5 Remaining endangerment: When an input terminal is connected to dangerous live potential it is to be noted that this potential can occur at all other terminals! CAT III - Measurement Category III is for measurements performed in the building installation. Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed...

Page 25: General Maintenance
MAINTENANCE Warning Except replacing fuse and battery, never attempt to repair or service the meter. Store the meter in a dry place when not in use. Don't store it in an environment with intense electromagnetic field. General Maintenance Periodically wipe the case with damp cloth and a little mild detergent. -
Page 26: Battery And Fuse Replacement
If the meter fails, check and replace ( as needed ) the battery and fuses, and/or review this manual to verify proper use of the meter. Battery and Fuse Replacement Warning To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the low battery indicator ( ) appears. - Page 27 To replace the fuse, remove the holster from the meter. Remove the screws on the back cover, open the back cover and move it aside gently. Replace the damaged fuse with a new one of the same ratings. Reinstall the back cover, the screws and the holster properly.
