5.3 Measurement of Resistances (R)
Important!
Make absolutely sure that all circuits and circuit components, as
well as other measurement objects, are no-load.
Connect the measuring leads supplied to the measuring device:
the red measuring lead to the „+" socket (red) and the black
measuring lead to the „−" socket (black)). Set the measurement
function switch to a range in the yellow sector („R") and set the
slide switch „R - L/C" to „R". With open measuring leads or high-
value/broken resistances „1" (for overflow) is displayed. Next,
connect the measurement probes to the measurement object. To
maintain the highest possible resolution (and thus the smallest
possible error of measurement), the measurement range must be
adjusted to the expected resistance. If, for example, the color
code rating indicates a value of 120 Ω, the range „200 Ω „ should
be set.
Note!
When you are measuring resistance, check that the measurement
points you touch with the measuring probes when measuring are
free of dirt, oil, soldering material, or similar, which are likely to
result in errors in measurement values.
With resistances greater than approx. 2 M Ω it may occur that the
display needs a few moments to stabilize itself. If „1" is display-
ed, you have exceeded the measurement range or the measure-
ment section has been interrupted.

6. Maintenance
Changing the battery is described in Section 4.1. For cleaning the
device or the display window, use only a clean, dry, antistatic lint-
free cleaning rag.
Important!
Never use cleaning agents containing carbon, petrol, alcohol or
similar since these will attack the surface finish of the measuring
device. Also, the vapors are a health and explosion hazard
