Wolfgang Warmbier SRM 110 Surface Resistance Meter User Manual
General
The SRM®110 is a pocket size and lightweight, surface resistance tester.
The built-in parallel bar electrode checks the surface resistance, but can
also be used to check “resistance to ground”.
Operating Instructions
Measuring Surface Resistance (Picture 1 and 2)
To measure the surface resistance of an object, hold the instrument with the
bar electrode to the surface and press the “TEST” button.
The value is indicated with 12 LED’s, in different colours
Other Measurements (Picture 3)
By connecting external electrodes to the instrument’s sockets it is possible
to measure for example “point to point” resistance with a Mini probe Model
410.
The LED’s indicate:
Measuring Resistance to Ground (picture 4)
- Plug in the supplied grounding cord to one socket of the instrument. The associated internal electrode is disconnected hereby.
- Connect the opposite end of the grounding cord to “ground” or a “groundable point”.
- Hold the instrument to the surface like described above and press the button.
