2. Mode switch rotary switch: This switch is used
to set the instrument operating modes and
measurement ranges. Turn OFF the instrument
when not in use to increase battery life
3. "FUN" function key: Press this key to select
between AC or DC voltage measurement and
resistor / diode / continuity mode measurement.
4. "D-H" Data Hold Button: Press this button to
hold the value displayed. Press the button again
to resume the measurement. This button is also
used to launch the unit from standby mode.
5. "M-H" Peak Hold Button: Pressing this button
holds the value displayed until the instrument
measures a higher value. The highest measured
value is always maintained. Press again to switch
to normal measurement
6. Measuring tip: Positive measuring point (the
measuring tip can be lowered into the front of
the instrument by rotating the retaining sleeve
counterclockwise, this function has significance
when stored)
