b) "R-H"
After this button is pressed once, the symbol "R-H" (for Range Hold) appears in the
display (left-hand edge) and the function "Auto Range" (= automatic range changing)
is no longer active. With each further operation of the button, the measuring range is
increased. The change of range can be seen on the one hand from the change of unit
of measurement and on the other hand from the position of the decimal point.
With resistance measurement in the lowest range, the continuity tester (<50 Ohm
acoustic) is activated, indicated by the corresponding symbol in the bottom left cor-
ner. To return to automatic range change, press the "R-H" button longer than approx.
1 s. As a result, the symbol "R-H" disappears from the display.
Note!
This special function is only possible (only selectable) during DC and AC volta-
ge measurement and during resistance measurement.
c) Measuring function switch or rotary switch
The measuring function switch must not on any account be
moved during measurement, as this can damage the measuring
instrument (separation arcing) and as a result the user may be
endangered in the case of voltages greater than 25 VAC rms or 35
VDC.
The measuring function switch must not on any account be set to
voltage measurement (=~V) during current measurement.
Arranged in a semicircle, the various measuring ranges can be selected by turning
the switch clockwise:

=400 mA =
