I. FREQUENCY MEASUREMENT (SEE FIGURE 10)
(figure 10)
Warning!
To avoid harm to yourselves, never attempt to inputan effective voltage over 60V in DC or
30V in AC.
The measurement range is 2kHz.
To measure frequency, connect the Meter as follows:
1. Insert the red test lead into the
Hz
terminal and theblack test lead into the
COM
terminal.
2. Set the rotary switch to
2kHz
.
3. Connect the test leads across with the object being measured.
4. The measured value shows on the display, the unit is
kHz
.
Note
- This measurement method is applicable to input scope<30Vrms. When the input scope
≥30Vrms, the input protection circuit may move which cause cannot getany reading.
- When frequency testing has been completed,disconnect the connection between the
temperature probe and the circuit under test.
