Please read these instructions carefully before use and retain for future 

reference.

This instrument is designed and manufactured in compliance with: G84793,  

lEC61010-1, CAT III 600V Pollution Degree 2 and Double Insulation standards.

• 

Check the test leads, probes and case insulation before using. If you find any 

breakage or abnormality, or you consider the device is broken, stop using the 

device immediately.

• 

When using the test probes, keep your fingers behind the finger protection ring.

• 

Do not use the meter with the back cover open.

• 

Select appropriate test range for measurements.

• 

Ensure all inputs are less than the range selected otherwise it may cause electrical 

shock or meter damage.

• 

Do not change the range selector position during voltage or current 

measurements.

• 

Do not apply a voltage over 600V between COM terminal and ground.

• 

Take caution when working voltages are above 60V DC or 30V AC rms.

• 

Do not connect the meter to voltage signals when the range selector is on current, 

resistance, diode or continuity range.

• 

When measuring current, each single measurement should be shorter than 10 

seconds. For current values over 5A, the wait period between each measurement 

must be longer than 15 minutes.

• 

When a measurement has been completed, disconnect the testing probes from 

the circuit under test.

• 

Replace the batteries as soon as the low battery indicator appears on the display.

• 

Remove dead batteries from the meter or if it is not going to be used for a long 

time.

• 

Never mix old and new batteries together, or different types of batteries.

• 

Never dispose of batteries in a fire, or attempt to recharge ordinary batteries.

• 

Before replacing the battery, turn off the meter and disconnect all the test probes.

• 

To prolong battery life turn off the meter after use.

• 

CAT III: Measurement category III is for measurements performed in the building 

installation. Examples are measurements on distribution boards, circuit-breakers, 

and wiring, such as cables, bus-bars, junction boxes, switches and socket-outlets 

in the fixed installation, and equipment for industrial application and some other 

equipment such as stationary motors with permanent connection to the fixed 

installation.

• 

Only use test leads and probes that are in compliance with IEC 61010-031, and 

rated CAT III 600V.
