selection button
Press this button to select between AC/DC
•
voltage measuring mode if the function switch
is in „V" position.
Press this button to select between AC/DC
•
current measuring mode if the function switch
is in „uA,mA,20A" position.
Press this button to select between Resistance/
•
Diode/Continuity/Capacity measurement
modes if the function switch is set to „Ω
(Resistance) / (Diode) /
(capacity)" position.
Press this button to select between °C and °F is
•
the function switch is set to °C/°F position.
Frequency and Duty Cycle
Press this button to select between
•
Frequency(Hz) / Duty cycle (%) modes if the
function switch is in „Hz/%" position.
RANGE selection button
On the first use the automatic range selection
•
is enabled.
You can activate the manual range selection
•
with the press of this button. By pressing the
button the device switches into manual mode
and the RANGE sign appears.
If the highest measuring range is reached, with
•
a press of the button the device goes back to
the lowest range.
By holding the RANGE button down for more
•
than 1 seconds, the RANGE sign disappears
and the device goes back to automatic range
mode.
HOLD button
If you would like to keep the last measured
•
value for a longer time, press this button (the
HOLD sign will appear, and the value will
stay on the screen until the next press of the
button).
By rotating the function switch the held data
•
automatically disappears.
REL (RELATIVE ZERO) button
This button is used for various (relative) starting
values and for comparing these.
