OPERATING INSTRUCTIONS
DC & AC VOLTAGE MEASUREMENT
1. Connect the red test lead to the “VΩmA” jack (center plug). Connect the black test lead
to the “COM” jack (right plug).
2. Set the manual range switch to the desired Voltage position. The DC Voltage positions
are on the left side of the range, marked with “V⎓”; the AC Voltage positions are located
on the right side of the range, marked with “V~”.
Note: If you are measuring an unknown voltage, set the range switch to the highest
range and reduce it until a satisfactory reading is obtained.
3. Turn the the device or circuit’s power to measure the voltage value. It will appear on the
digital display along with the voltage polarity.
