To Ensure Safe Usage

●Excitation voltage should be 2 VDC.
●Use screws for mounting. Mounting using an adhesive may result in a shock when removing, and this may lead to damage.
●When affixing the object to be measured, use the following screws.
Metric course thread M2.5, M2.6, or unified screw thread No.2-56UNC
●When mounting with screws, slightly apply silicone oil or grease to the contact surface.
Resultant closer contact will ensure better fixing condition.
