IMPORTANT SAFETY INFORMATION

Please read these instructions carefully before use and retain for future reference.

• 

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 exceeding the marked voltage 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. 

•  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.
