Thanks for buying our product. Please go through the instruction manual before starting to use
the meter.
Safety Instructions
To avoid an electric shock or injury, read and follow the instructions. If at all unsure seek advice
from a suitably competent and qualifies person before use. Retain instructions for future reference.
• Check the meter and leads before use, if damaged do not use. Ensure insulation around leads
and connectors are not damaged. This product has no serviceable parts
• Do not use in area where there is flammable vapour or gas
• Do not use above the marked voltages
• When measuring current, turn off the circuit before using the meter
• Keep fingers behind the fingers guards on the probes and remove probes before replacing the
battery. Do not use without the battery cover. Replace battery when the low battery indicator
appear
• Connect the common test lead before the live test lead, when disconnecting, disconnect the
live lead first
• Caution when working above 30V AC, 42V peak or 60V DC as these pose a shock hazard.
Do not measure voltages above 500V in category 1 installations
