OPERATING INSTRUCTIONS DC VOLTAGE MEASUREMENT 1. Insert the black and red test leads into the COM and VΩHz input terminals respectively. 2. Set rotary switch at desired V — - - - position. Select the desired DC voltage range, or set automatic range. 3. When the magnitude of voltage to be measured is unknown, always start with the highest range. 4. Connect the test lead tips in parallel with the circuit to be measured. Be careful not to touch any electrical conductors. 5. The polarity of the red lead connection will be indicated along with the voltage value. 6. Read the measurement directly from the display. AC VOLTAGE MEASUREMENT 1. Insert the black and red test leads into the COM and VΩHz input terminals respectively. 2. Set rotary switch at desired V~ position. Select the desired AC voltage range, or set automatic range. When the magnitude of voltage to be measured is unknown, always start with the highest range. 3. Connect the test lead tips in parallel with the circuit to be measured. Be careful not to touch any electrical conductors. 4. Read the measurement directly from the display. 10
AC CURRENT MEASUREMENT 1. Set the rotary switch at A~ position. 2. Place only one conductor between the open jaws. 3. Read the measurement directly from the display. RESISTANCE MEASUREMENT 1. Insert the black and red test leads into the COM and VΩHz input terminals respectively. 2. Set rotary switch at desired Ω position. 3. Push F.FUNC. button to select Ω. 4. If the resistance being measured exceeds the maximum value of the range selected or the input is not connected, an overrange indication “OL” will be display and the higher range has to be selected. 5. Read the measurement directly from the display. NOTE: 1. If the resistance being measured exceeds the maximum value of the range selected or the input is not connected, an overrange indication “OL”will be displayed. 2. When checking in-circuit resistance, be sure the circuit under test has all power removed and that all capacitors have been discharged fully. 3. For measuring resistance above 1MΩ, the meter may take a few seconds to get stable reading. This is normal for high resistance measurements. 4. When the input is not connected, i.e. at open circuit, the figure “OL” will be displayed for the overrange condition. 11
