EX715 Iss.4

7. Maintenance

8. Calibration

The charge plate in the top of the meter should be kept clean. It is important to keep this 
area free from dust and fluff, and must not be touched in operation, as this will affect the 
reading.

Apart from replacing the battery, there are no user serviceable parts inside the EX715. If 
there is a malfunction it should be returned to the manufacturer. The guarantee is void if 
the instrument is taken apart.

The EX715 is calibrated as standard using a 150mm x 150mm or other sized plate. If the 
instrument is used in hazardous areas then we recommend an annual recalibration.

If you need further information about static electricity problems, please contact the 
manufacturers or authorised distributors.
