Note:
- To obtain a more precise reading, you could remove the objects being tested from the circuit
when measuring.
- To avoid harms to you or damages to the Meter from eletric shock, do not attempt to input
voltages higher than 33V AC or 70V DC.
- When diode testing has been completed, disconnect the connection between the testing leads
and the circuit under test and remove testing leads from the input terminals.
E. Frequency and Duty Cycle Measurement (see figure 7)
Warning!
To measure frequency, connect the Meter as follows:
1. Insert the red test lead into the VΩHz terminal and the black test lead into the COM terminal.
2. Set the rotary switch to %Hz. Frequency measurement mode is a default or press
button to switch to duty cyclemeasurement mode.
3. Connect the test leads across with the object being measured. The measured value shows on
the display.
Note:
When frequency measurement has been completed, disconnect the connection between the
testing leads and the circuit under test, and remove the testing leads away from the input terminals
of the Meter.

To avoid harms to you or damages to the Meter from eletric shock, do not
attempt to measure voltages higher than 750V AC or 1000V DC, although
figure 6
readings may be obtained.
