Page 5: Operation
OPERATION DC or AC Voltage Measurement Warning: To avoid personal injury, or damage to the meter from electric shock, please do not attempt to measure voltages higher than 1000V although readings may be obtained. To measure DC/AC voltage, connect the meter as follows: •... -
Page 6: Measuring Resistance
Warning: To avoid damage to the meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring resistance. To avoid possible injury, please do not attempt to input voltages higher than 60V DC or 30V AC. -
Page 7: Frequency Measurement
Diode Test Perform the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, and then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V. - Page 8 Temperature Measurement To measure temperature, connect the meter as follows: • Set the rotary switch to ºC to measure degree celsius temperature. • Insert the multi-purpose socket into the corresponding Hz and COM terminal. • Insert the temperature probe to the corresponding input terminal of the multi- purpose socket.

MAINTENANCE Cleaning • Periodically wipe the case with damp cloth and mild detergent. Do not use abrasives or solvents for cleaning. • Clean the measurement probe tips occasionally, as dirt on the probes can affect reading accuracy. Replacing the fuses •... - Page 12 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.
