OPERATING INSTRUCTIONS
DC CURRENT MEASUREMENT
1. Connect the red test lead to the "V
black test lead to the "COM" jack.
2. Set the range switch to the desired A
3. Open the circuit in which the current is to be measured,
and connect the test leads in series with the circuit.
4. Read the current value on the LCD display along with
the polarity of the red test lead.
DC VOLTAGE MEASUREMENT
1. Connect the red test lead to the "V
black test lead to the "COM" jack.
2. Set the range switch to the desired V
voltage is not known beforehand, set the range switch
at the highest range position and then reduce it range
by range until satisfactory resolution is obtained.
3. Connect the test leads across the device or circuit to be
measured. Read the voltage value on the LCD display
along with the polarity of the red test lead.

AC VOLTAGE MEASUREMENT
