Check the circuit with the voltage function to make sure the meter reads 0. When you measure resistance, the unit supplies a small current, so there must be no other current source. Continue turning the dial counterclockwise – all the way to 200 µ if necessary – to increase the accuracy of the reading. Turn on the meter and take another reading. If it”s below 0.2 amps, turn off the meter, place the red lead into the VmA jack and turn the dial one position counterclockwise to the 220m setting in the DC amp (DCA) area. Turn the dial to the 10 amp (10A) area, make sure the meter is on, touch the leads to the exposed circuit wires and note the reading. To measure current, switch the red lead to the 10 ADC jack and leave the black one in the COM jack.

If the reading is less than 20, move the dial to that setting. If the reading is less than 200, move the dial to that setting. Take the reading by touching the leads to the exposed circuit wires. To measure DC voltage, leave the red lead in the jack marked VΩmA and the black lead in the jack marked COM and turn the dial counterclockwise to the 1000 setting in the DC voltage section (DCV). If it is less than 250 volts, turn the selector to the 250 setting in the AC voltage section to get a more accurate reading. Touch the leads to the exposed wires of the circuit you are testing and note the reading. Plug the red lead into the jack marked VΩmA and the black lead into the jack marked COM. To measure AC voltage, rotate the selector to point to 750 in the AC voltage section (ACV) at the top.
Turn this on to activate the LED display. On the left side, you”ll see a multipin transistor /hFE jack for testing transistors.
The meter comes with a pair of leads, one black and one red, that fit into these jacks. They are marked – from top to bottom – 10ADC, VΩmA and COM. You”ll notice three jack inputs arranged in a vertical line on the bottom right. Use this wheel to select the function you need and the sensitivity of the measurement you”re going to make. Note the main selector wheel on the front of the multimeter.
