AC VOLTAGE MEASUREMENT 1. Red lead to “V Ω mA”. Black lead to “COM” (for measurements between 200mA and 10A connect red lead to “10A” jack with fully depressed.) 2. RANGE switch to desired DCA position. 3. Open the circuit to be measured, and connect test leads INSERIES with the load in with current is to measure. 4. Read current value on Digital Display.
