User Manual

For example: 0,4% / °C for copper. A copper conductor, that has a
resistance of 10.00 mOhm at 20°C will increase to 10.40 mΩ at
30°C. This change should be taken into account, when making
measurements.
A current going through a resistance will also elevate its
temperature. So duration of the test can change the resistance.
When measuring the resistance of item, such as current shunts,
which have joints of dissimilar conductors, thermal EMF can affect
the accuracy of the measurement. This condition can be detected if
the reading altes, when the leads are reversed. To compensate for
this effect, the average of the two readings should be taken as the
true measurement.
6. Fuse replacement
The milliohm- and current measurement ranges are each protected
by a separate fuse (FF500mA/250V). If one of these fuses is melted
and it is no longer possible to measure any values, the fuse must
be replaced. Use only fuses with the same technical specifications.
Proceed as follows:
1. Turn the meter off and remove the test-leads.
2. Remove the four screws on the battery compartment.
3. Remove the battery cover.
4. Remove the fuse from the fuse holder and replace it with a new
one.
5. Close the battery compartment and tighten the four screws
