10. Operation
10.1 VOLTAGE MEASUREMENT
Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
Set the rotary switch in the desired "
1.
Press "SELECT" to choose the AC or DC measurement mode.
2.
Connect the red test lead to the "VHz" jack and the black lead to the
3.
"COM" jack.
4.
Connect the test leads to the source being measured.
5.
Read the voltage value and the polarity of the red test lead on the LCD
display.
Notes
In the AC range, press "Hz%" to measure the frequency or duty cycle.
10.2 CURRENT MEASUREMENT
Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.

1.
Press "SELECT" to choose the AC or DC measurement mode.
2.
Connect the red test lead to the "VHz" jack and the black test lead to
3.
the "COM" jack (switch the red lead to the "10A" jack for
measurements between 400 mA and 10 A).
4.
Open the circuit in which the current is to be measured and connect
the test leads to the circuit IN SERIES.
5.
Read the current value and the polarity of the red lead connection on
the LCD display.
Notes
In the AC range, press "Hz%" to measure the frequency or duty cycle.
