SR-496 Surface Resistance Meter
Instruction Manual
The surface resistance can be measured by attaching two parallel electrodes of the instrument to the surface
of the measured object. Thus you can determine whether the measured object is a conductor, anti-static
material, or an insulator. The instrument is particularly suitable for a variety of anti-static areas.

※The signal is weak when measure surface resistance of 1011 Ω or more, in order to ensure stable and
reliable measurement, it is necessary to make environment where electromagnetic interference is small.
During the measurement process, make sure that no person walks within 3 meters.

F. Operation Instruction
1. Power On
Press " " button to turn on the instrument. About 1 sec., the instrument will be ready to measure.
2. Resistance Display Mode
Press " " to switch the resistance display mode: Order of magnitude mode/conventional mode.
3. Backlight
After power on, press " " button to turn on/off the backlight.
4. Temperature Unit Conversion
Long press " " button to switch the temperature units: Celsius (°C) and Fahrenheit (°F).
5. Resistance Measurement
After turning on the instrument, put the instrument on the surface of measured object, press and hold
"" key to start measurement, at the same time, the “TEST” indicator will be displayed.
During measurement, resistance display area displays "----" (on normal mode) or "--x-" (on order of
magnitude mode), indicating that the instrument is measuring.
After the resistance value is measured, the resistance value will be displayed in resistance display area.
When the resistance value is higher than measurement range, resistance display area will show “HI”.
When the resistance value is lower than the measurement range, the “Lo” will be displayed.
After releasing the measurement button, the measurement will finish and the data will be held,
"HOLD" indicator shows up simultaneously.
6. Shutdown
After power on, long press " " button to shut down.
If there is no operation within 30 seconds, the instrument will shut down automatically.
