Introduction
WARNING
To avoid user injury and multimeter damage, the
multimeter must be set to the correct value of mains
voltage before connecting the power lead to the mains and
switching on.
Before doing any measurements always examine the multimeter and accessories
for any damage, contamination (excessive dirt, grease, etc.) and defects. Examine
the test leads for cracked or frayed insulation and make sure the lead plugs fit
snugly into the multimeter sockets. If there are any abnormalities, do not attempt
to do any measurements.
