4.1. RESISTANCE TEST 1. Set the function switch to the highest Ω position. 2. Insert the test leads into COM (Black lead) and "+" socket (Red lead) 3. Short the test leads and turn 0Ω adjusting knob to set the pointer to zero position. 4.
4.4. ACV TEST 1. Set the function switch to the highest ACV position. 2. Insert the test leads into COM (Black lead) and "+" socket (Red lead) 3. Connect the test leads to the circuit being tested, regardless of the polarities. (Fig.03) 4.
4.8. Iceo (LEAKAGE CURRENT) TEST 1. Insert the test leads into COM (Black lead) and "+" socket (Red lead). 2. Set the function switch to X10 (15mA) for small size transistor, or to X1 (150mA) for big size transistor. 3. Short the test leads and turn on adjusting knob to set the pointer to the zero position.
