is higher than the measurement threshold, it displays OPEN, otherwise it displays the
measured voltage value. The measurement threshold for diode is 3V. The diode

2. According to Figure 2.6.2, connect the red and black test leads respectively to the
proper input terminals.
3. According to Figure 2.6.2, connect the test leads to the terminals of the diode and
read the display.

5.6.2 On-off Test
1. When in the diode test mode, press
Cont
to select the on-off measurement.
When the measured resistance value is greater than the threshold of the buzzer, it
displays OPEN, and when the measured resistance value is smaller than the threshold of
the buzzer, the
resistance will be displayed. The threshold of the buzzer is 10Ω. The on-off
measurement interface is shown in Figure 2.6.3:
