Specific Measurements
The SRM500K can take specific measurements: Resistance
between Two Points (RTT) and Surface to Ground Resis-
tance (RTG). Procedures vary regarding sample prepara-
tion, probe preparation and spacing of the 5 pound probes.
Select and read the correct test procedure for the desired
measurement.
RTT test procedure
This procedure measures resistance between two points in-
dependent of a ground point.
1. Connect the plug ends of the test leads into the 3.5mm
jacks of the meter.
2. Connect the banana plugs of the test coil cords into the
ends of the 5 pound probes.
3. Place both probes on the material according to test pro-
cedures.
4. Move switch to desired test voltage position, either 10
or 100 V.
5. Press and hold the test button until power is applied to
the meter and a value is displayed. Keep the button de-
pressed with sufficient force until the electrical resis-
tance. Relative humidity and temperature readings are
displayed on the meter screen.
