DC VOLTAGE MEASUREMENT 1. Connect red test lead to “V Ω mA” jack, Black lead to “COM” jack. 2. Set RANGE switch to desired DCV position, if the voltage to be measured is not known beforehand, set switch to the highest range and reduce it until satisfactory reading is obtained. 3. Connect test leads to device or circuit being measured. 4. Turn on power of the device or circuit being measured voltage value will appear on Digital Display along with the voltage polarity.
