    5.2 Switch on Switch off Depress on/off button. After sound indication (beep), place device on surface to be measured. Depress red button on top of device. This puts device in measurement state. Measuring parameters and sampling length will keep the last settings/readings before the shutdown of the meter. Depress on/off button a second time to shutdown.

    5.5 Calibration Before use, calibration should be done with the standard sample plate. For example, there is a standard sample plate pointed to 3.14. In shutdown condition, Press and hold the start button. Release the start button. The tester will enter the status of Calibration as shown below.

    After measuring, the new standard sample plate value will be stored to the memory instead of the old one. If the user has multi-reticle sample plate, he can choose the suitable sample plate to calibrate the tester against his measuring range in common use. This way, the tester’s precision can be improved greatly.

    save the energy, and have the battery recharged promptly when necessary.  The sensor is the precision part of the tester and particular care should be taken of it. After each use, put on the protective sheath gently to avoid violent shock to the sensor.
  • Page 13  Sample Length is the benchmark used to distinguish its surface roughness.  Evaluation Length is the necessary length for evaluating the roughness profile. It may include one or more sampling lengths.  Ra: Arithmetical Mean Deviation of the Profile is arithmetic mean value of the deviation of the profile within sampling length.
