IMPORTANT SAFETY INFORMATION
Please read these instructions carefully before use and retain for future 

reference.

• 

When using electrical appliances basic safety precautions should always be 

followed.

• 

Use the meter only as specified in this manual, or the protection provided may be 

impaired.

• 

Do not operate the meter or use test leads if they appear damaged, or if the meter 

is not operating properly. 

• 

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

personnel.

• 

Do not apply voltage between the COM and OHM terminals, while in the 

resistance measuring state.

• 

Do not measure current with the test leads inserted into the voltage or OHM 

terminals.

• 

Do not expose the instrument to direct sunlight, extreme temperature or humidity.

• 

Before measuring current, check the fuses and turn the power to the circuit off 

before connecting the meter to the circuit.

• 

Disconnect circuit power and discharge all high voltage capacitors before testing 

continuity. diode, resistance, capacitance or current.

• 

Do not use the meter around explosive gas or vapour.

• 

When using the test leads, keep your fingers behind the finger guards.

• 

Remove test leads from the meter before opening the meter case or battery door.

• 

Never operate the meter with the cover removed or the battery door open.

• 

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

• 

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

• 

Fit a full set of batteries at one time.

• 

Remove dead batteries from the appliance 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.
