Please read these instructions carefully before use and retain for future 

reference.

• 

This meter is designed to meet IEC61010-1, 61010-2-032, and 61010-2-033 in 

Pollution Degree 2, Measurement Category (CAT I 1000V, CAT II 600V, CAT III 

300V) and double Insulation.

• 

When using electrical appliances basic safety precautions should always be 

followed. 

• 

Please operate according to this manual, otherwise the protection provided by the 

device will be impaired or fail.

• 

There are no user-serviceable parts in this product. Refer servicing to qualified 

personnel.

• 

Use only the test leads supplied or the protection may be impaired.

• 

Check the test leads, probe and case insulation condition before using. If you find 

any breakage, damage 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 rings. 

• 

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

shock or meter damage.

• 

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

• 

Do not use the meter with the battery or fuse covers removed.

• 

Do not adjust the range selector during measurement.

• 

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.
