Cleaning

Clean the appliance regularly with a soft, dry cloth. Do not use 

cleaning agents or solvents; these may be aggressive to the plastic 

parts in the appliance. Ensure that no water can get into the interior of 

the appliance.

Dirt or moisture in ther ports can affect readings. Periodically clean 

them out with the following directions:

1.  Ensure the mode dial is in the ‘OFF’ position and the test leads are 

removed.

2.  Shake out any loose dirt which may be caught in the terminals.

3.  Soak a swab in cleaning alcohol.

4.  Work the swab around the interior of each terminal.

Storage

Switch off the tool and store it in a dry location which is not accessible 

to unauthorised persons.

Do not store it in an environment with intense electromagnetic fields.

Remove the batteries before storage if the tool will not be in use for a 

long time.

MAINTENANCE

*  If the voltage being measured is >300V, the display may show a 

value, but the measurement is dangerous.

*  If the current being measured is >10A, the display may show a 

value, but the measurement is dangerous.

WARNING! 

BEFORE CLEANING YOUR TOOL OR 

CARRYING OUT ANY MAINTENANCE PROCEDURE, 

MAKE SURE THAT THE POWER SUPPLY HAS BEEN 

REMOVED OR DISCONNECTED TO PREVENT 

ACCIDENTAL STARTING.
