How to Use Analog Multimeter
- 1). Examine the analog meter's scale and note the adjustment screw near the needle's pivot point. If the needle isn't pointing directly to the zero line at the left end of the scale, use the screwdriver to turn the adjustment screw until the needle lines up with zero.
- 2). Turn the rotary function knob to select the resistance scale of ohms x 100. Touch the tips of the red and black meter probes together to create a short. The needle will swing over to the right. Turn the resistance adjust thumbwheel until the needle points to zero on the ohms scale. Take the 100-ohm resistor and touch one probe tip to one resistor lead and the other probe tip to the other lead. The needle should move to roughly the 100-ohm mark on the scale. Set the resistor aside.
- 3). Turn the function knob to select the resistance scale of ohms x 1,000. Touch the probe tips together and adjust the thumbwheel until the needle points to zero on the ohms scale. Use the probe tips to measure the resistance of the 100K-ohm resistor. As in Step 2, the needle should register near the 100 mark on the ohms scale. Set the resistor aside.
- 4). Turn the function knob to select direct current (DC) volts. Touch the tip of the red probe to the battery's positive terminal and the black probe to the negative terminal. If the battery is fresh, you should see a reading of about 9 on the volt scale. Disconnect the probes from the battery.
- 5). Touch the capacitor's positive lead to the battery's positive terminal and the negative lead to the negative terminal. Set the battery aside. With the meter still set to measure volts, touch the positive probe to the positive capacitor lead and the negative probe to the negative lead. Observe a voltage reading on the meter that starts at around 9 and slowly drops to zero.
