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.

• 

Before using the meter, check the insulation around the input terminals of the 

instrument. Do not use if any damage is present.

• 

Do not operate the meter, or use the probes, 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.

• 

Verify the meter’s operation by measuring a known voltage.

• 

Do not apply more than the rated voltage as marked on the meter, between the 

terminals or between any terminal and earth ground.

• 

Use caution with voltages above 30V AC true RMS, 42V AC or 60V DC. These 

voltages pose a shock hazard.

• 

Do not use the meter around explosive gas or vapour.

• 

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

probe.

• 

Comply with local and national safety code. Wear personal protection equipment 

(such as rubber gloves, masks and flame retardant clothes etc.) to prevent being 

injured by electric shock due to exposed hazardous live conductors.

• 

When measuring, connect the zero line or the ground line first, then connect the 

live wire. When disconnecting, ensure that you disconnect the live wire first and 

then disconnect the zero line and ground line.

• 

Remove any probes 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.

• 

Do not connect the meter to any voltage source while the rotary selector is in the 

current, resistance, capacitance, diode or continuity range.

• 

If the probe is damaged, replace it with the same model number and same 

electrical specifications.

• 

Only use the batteries recommended for this product.

• 

Ensure that the batteries are inserted correctly, observing the plus and minus 

marks on both the batteries and the compartment.

• 

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.
