Please read these instructions carefully before use and retain for future reference.
Check the test leads, probes and case insulation before using. If you nd any
breakage or abnormality, or you consider the device is broken, stop using the device immediately.
When using the test probes, keep your ngers behind the nger 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 1000V 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 re, 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 xed installation, and equipment for industrial application and some other equipment such as stationary motors with permanent connection to the xed
installation.
Only use test leads and probes that are in compliance with IEC 61010-031, and rated CAT III 1000V.
