- Do not store the DVM851 in temperatures that are too high or too low.
- Do not store the DVM851 in direct sunlight.
Before Use
- Make sure that the DVM851 is turned off before connecting the test leads.
- Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
- Set the rotary switch to the desired range.
- To measure voltage, connect the test leads across the voltage source.
- To measure current, connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack. Insert the black test lead into the "10A" jack to measure currents up to 10 amps.
- To measure resistance, connect the test leads across the resistor.
- To test a diode, connect the red test lead to the anode of the diode and the black test lead to the cathode. The meter should display a reading in one direction and a very low reading in the other direction.
- To test a transistor, connect the red test lead to the emitter of the transistor, the black test lead to the base, and the other test lead to the collector. The meter should display a reading in one direction and a very low reading in the other direction.
