3) Timing Measurement

Short press the TIMING button to turn on timing measurement and the LCD will display timing measurement,

as shown in Picture 17. During timing measurement, when the set time has elapsed, the measurement will be

terminated automatically. For the set time, please refer to the description of SET button.

4) Comparative Measurement

Short press the COMP button to turn on comparative measurement (as shown in Picture 18) and the “000M” in

the “Set Value: 000MΩ” will flash. Press the UP/DOWN button to adjust the value and LEFT/RIGHT button to

adjust the carry, starting from the last flashing bit “M” by default. Press the OK button to complete the desired

set value for comparison. Then press the TEST button to start measurement.

If the measured value is greater than the set value, it will be deemed a pass, and "PASS" will be displayed on

the screen, as shown in Picture 19.

If the measured value is less than the set value, it will be deemed a fail, and "FAIL" will be displayed on the

screen, as shown in Picture 20.
