Diode Measurements
1. Insert the black test lead banana plug into the negative COM jack and the
red test lead banana plug into the positive diode jack.
2. Turn the rotary switch to the / •))) position.
3. Touch the test probes to the diode under test. Forward voltage will indicate
400 to 700mV. Reverse voltage will indicate “I”. Shorted devices will
indicate near 0mV. Shorted devices will indicate near 0mV and an open
device will indicate “I” in both polarities.
Battery Test
1. Insert the black test lead banana plug into the negative COM jack and the
red test lead banana plug into the positive V jack.
2. Select the 1.5V or 9V BAT position using the function select switch.
3. Connect the red test lead to the positive side of the 1.5V or 9V battery and
the black test lead to the negative side of the 1.5V or 9V battery.
4. Read the voltage in the display.
