will recover the working condition.
If presses the ‘FUNC.’ when power is on, auto power off

PREPARATION FOR MEASUREMENT
4.8.1 Put on the ‘ON/OFF’ button. If the battery voltage is
less than 3.8V, display will show ‘ ’, the battery
should be changed at this time.
4.8.2 The ‘ ’ besides the input jack shows that the input
voltage or current should be less than specification on
the sticker of the meter to protect the inner circuit from
damaging.
4.8.3 Select a function and a range for the item to be
measured through rotating the transform switch
accordingly. When the value scale to be measured is
unknown beforehand, set the range selector at the
highest position.
4.8.4 When connection, first connect to the public testing line,
then to the electriferous testing line. When you’ll
remove it, you should remove the elecriferous one.
4.9 MEASURING DC VOLTAGE
WARNING
You can’t input the voltage which more than 600V DC,
it’s possible to show higher voltage, but it’s may
destroy the inner circuit.
Pay attention not to get an electric shock when
measuring high voltage.
