C 5 Operating modes, display details and symbols
a) Diode test
The value displayed during diode test is the forward voltage at
the approx. 1
test current. The measuring range here is 0 to
approx. 2.0 V.
b) Continuity testing
In continuity testing, the continuity of voltage-free leads, plug-in
connections or fuses can be checked both acoustically and opti-
cally. An acoustic signal sounds where the resistance is lower
than 50 Ohm.
c) Negative polarity
When the test leads are reversed or with negative polarity, a
sign appears in front of the measured value.
d) “D-H” Data Hold
e) “R-H” (= Range Hold = manual range selection)
After this button is pressed once, the symbol “R-H” (for Range
Hold) appears in the display and the function “Auto Range’ (=
automatic range changing) is no longer active. Each time this
button is pressed, with voltage measurement the measurement
range is increased and with resistance measurement the range is
decreased. 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. 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.
Attention!
This special function is only possible (only

during resistance measurement.
