Precautions
Warning
1. Do not touch the electrodes during measurement . This could cause a shock.
2. Do not operate with wet hands. This could cause a shock.
3. Do not plug objects other than the provided connection wires into the jacks on this
device. Wiring earphones to listen could not only break the device but also
dangerously damage user’s hearing ability.
Caution
1. This product is for measuring surface resistance of solid matters. Do not use for any
other purpose.
2. Please keep in mind that the power switch may be inadvertently turned on by
pushing the measuring switch when turning the main unit upside down. The power
supply automatically turns off in about 35 seconds (about 20 seconds with mode
switching).
3. Note that precise measurement can not done under these conditions;
+ The electrodes are soiled.
+ Human bodies are coming into contact with the wires or alligator clips or
electrode.
+ Not in a specified environment.
+ Under noisy environments such as electromagnetic waves
4. Do not disassemble this device. This could cause malfunction.
5. When the device will not used for an extended period, store without the battery.
6. For this is a precision device, avoid strong impact, vibration and high temperature.
Preparation
Install the battery. Remove the protective case and
1
remove the 4 screws on the back side, the main
case opens. Connect alkaline batteries (6LR61 /
6LF22) correctly.
Press the measuring switch, confirm that the
numerical value is displayed on the display panel,
and then attach the main unit case and protective
case in reverse order.
* Please be careful not to touch the board. Touching the board unnecessarily may
cause failure.
* Since this machine consumes large power, be sure to use alkaline dry batteries.
* If the screw is tightened too much, the screw thread may be damaged. Please be
careful with over tightening.
Bring it from a place with a low temperature to a place with a high temperature, if
2
condensation occurs on the main body, wipe out moisture and leave it in the
measurement environment for about 30 minutes before conducting measurement.
We recommend that you leave the object to be measured and this machine in the
measuring environment beforehand and get used to it so that condensation does
not occur.
