4. Once any button is pressed, Figure 2-13 shows on the display indicating open calibration is in progress.

5. After a couple of seconds, the open calibration is completed. If the result is good, a calibration done
message will be shown on the display indicating the whole self-calibration process is completed. Please
press any button to return to the measurement mode.

6. If the result is out of range, a fail message will be on the display as Figure 2-15 shows. Please press any
button to return to the measurement mode. If necessary, please start the self-calibration process again from
the beginning.

NOTE
(1) It is recommended that the user performs open/short calibration before making precision measurements.
(2) When doing short calibration, please always keep the tips shorted firmly. The calibration process may fail if
the tips are in poor contact condition during the short calibration process.
(3) The distance between the tips creates small parasitic capacitance. When such distance varies (i.e. measuring
components with different sizes), the parasitic capacitance varies as well. Therefore, when doing open
calibration, please keep the tip distance as close as possible to the actual size of the component to be
measured. It can compensate for the parasitic capacitance most accurately.
(4) After the battery is completely dead or hardware reset is performed, all the self-calibration data will be
removed. Please perform self-calibration again if necessary.
