10.2 CURRENT MEASUREMENT
Do not measure circuits that may contain voltages > 600 VDC or
> 600 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!
1. Set the rotary switch in the desired “ ”, “ ” or “ ” position.
2. Press “SELECT” to choose the AC or DC measurement mode.
3. Connect the red test lead to the “VHz” jack and the black test lead to
the “COM” jack (switch the red lead to the “15A” jack for
measurements between 600 mA and 15 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.
10.3 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Set the rotary switch in the “Ω ” position.
2. Connect the red test lead to the “VHz” jack and the black test lead to
the “COM” jack.
3. Connect the test leads to the resistor to be measured and read the
LCD display.
10.4 CAPACITANCE MEASUREMENT
Do not conduct capacitance measurements on live circuits. Make
sure all capacitors in the circuit are depleted.
1. Set the rotary switch in the “Ω ” position.
2. Press “SELECT” to choose the capacitance measurement mode.
3. Connect the red test lead to the “VHz” jack and the black test lead to
the “COM” jack.
