Introduction
The SRM110 is a pocket size, lightweight, auto ranging surface resistance tester. Its internal
parallel electrodes comply with DIN EN 100 015/1. IEC electrodes can be externally
connected for tests according to IEC 61340-4-1. The measuring voltage is autoranging 10V
to 100V.
Operation Instruction
Measuring Surface Resistance
• To measure the surface resistance of an object, hold the instrument to the surface and
press the "TEST" button.
• Thevalueisindicatedwith12LED's,indifferentcolours.

11 ΩElectrostatic dissipative
Red 1012 Ω-> Electrostatic insulating
Measuring Resistance to Ground
• Plug in the supplied grounding cord at 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.
Other Measurements
By connecting external electrodes to the instrument's sockets it is possible to measure for
example "point to point" resistance, or "volume resistance".

Notice
The Electrostatic Field Meter is not approved for measurements in explosion hazard areas!
High electrostatic charges or measuring insulating highly charged materials might
damage the instrument!
Using the instrument in power plants is not permitted.
Maintenance
When the (>)-LED flashes during measurement, it is due to replace the 9V battery.
Open the back cover of the instrument by unscrewing the four screws. Take care of the
polarity.
Calibration
Recalibration is recommended once a year.
