, to call up the
measurement screen.
 Connect the meter to the tested
object.
 Measurement starts automati-
cally.
 During the measurement the
H.V./REC/CONT. diode is lit
green and a sound signal is
emitted.
NOTE!
Display of symbols indicates that the tested object is live. The
measurement is blocked. The meter must be immediately disconnected from the
object.
