4. The tested circuit overload resistance value shows on the display.
5. The beeper comes on continuously for open conditions, that is test resistance ＜10Ω.
6. The beeper does not sound when the test resistance is ＞100Ω
When measuring continuity buzzer, the corresponding functional buttons:
CONTINUITY REL
F1 F2
F1: toggle to resistance measurement mode
F2: relative mode
Note:
z When continuity testing has been completed, disconnect the connection between the testing leads
and the circuit under test and remove the test leads away from the input terminals.\
vi. Measuring Frequency / Duty Cycle
Warning
To avoid harms to you, please do not attempt to input voltage higher than 42V rms.
To measure frequency and duty cycle, connect the Meter as Figure 3-9 and do the following:
BlackRed
Figure 3-9. Measuring Frequency / Duty Cycle
1. Insert the red test lead into the Hz terminal and the black test lead into the COM terminal.
2. Set the rotary switch to Hz.
3. Connect the test leads across with the object being measured.
4. The measured value shows on the display.
5. Press MODE button to toggle between Multimeter mode and Scope mode.
6. Press F1 to toggle between frequency and duty cycle measurement.
When measuring frequency and duty cycle, the corresponding functional buttons:
\Freq/Duty
F1
F1: toggle between frequency and duty cycle
