MEASURING CAPACITANCE

• 

Plug the black test lead into the 

COM

 jack and the red test lead into 

the 

INPUT

 jack.

• 

Set the rotary selector to the      range position.

• 

After fully discharging the capacitor, connect the test leads to the 

two ends of the capacitor for measurement.

• 

Take the reading on the LCD.

Note: It may take some time (about 30 seconds for the 400μF and 

4000μF range) for steady reading when measuring high capacity.

• 

You must push the “

REL

” button when measuring less than 20nF.

WARNING

• 

Beware of electrocution.

• 

To avoid electric shock, make sure that the capacitors have been fully discharged 

before measuring the capacitance of a capacitor.

 

MAINTENANCE

WARNING

• 

When replacing batteries, make sure that the test leads have been moved away 

from the circuit under measurement before opening the battery cover of the 

meter, in order to avoid electric shock.

• 

When replacing test leads, make sure the replacements are in good working 

condition with the same or equivalent rating: 1000V 10A.

Replacing Batteries

• 

If the low battery symbol appears, it means that the batteries should be replaced.

• 

Loosen the fixing screw of the battery cover and remove it.

• 

Replace the exhausted batteries with new ones.

• 

Put the battery cover back on and return the fixing screw.

Replacing Test Leads

• 

A test lead must be replaced if the insulation layer has been damaged or if the wire 

inside is exposed.

INFORMATION ON WASTE DISPOSAL FOR CONSUMERS OF 

ELECTRICAL & ELECTRONIC EQUIPMENT

These symbols indicate that separate collection of Waste Electrical and 

Electronic Equipment (WEEE) or waste batteries is required. Do not dispose 

of these items with general household waste. Separate for the treatment, 

recovery and recycling of the materials used. Waste batteries can be 

returned to any waste battery recycling point which are provided by most 

battery retailers. Contact your local authority for details of the battery and 

WEEE recycling schemes available in your area.

measurement.

• 

If the resistance of the circuit being tested is less than 40Ω, the built-in buzzer  

may sound.

• 

Take the reading on the LCD.

Note: If the test leads are open or the resistance of the circuit is over 400Ω, “OL” will 

appear on the LCD.
