- Connect the test leads: Insert the red test lead into the “Input” jack and the black test lead into the “COM” jack.

- Turn the rotary switch to the “v-” or “v~ “setting according to the measured voltage.
- Connect the circuit: Connect one end of the test leads to the circuit that needs to be measured, in parallel with the circuit.

- Reading: record the reading from the LCD screen.
- After measuring, turn the rotary switch to the OFF position to turn off the meter.
NOTE:
- When a small measuring range is selected, the display of the multimeter may show unstable results if the test leads are not connected to the load. This is a normal event and will not affect the measurements.
- During DC voltage measurements, use the ” – ” symbol on the screen to judge the polarity of the red test lead connection. Without the ” – ” symbol onscreen, the red test lead is connected with positive polarity.
- To avoid damaging the meter, do not measure voltages exceeding 600V DC or 600VAC.
- If necessary, the “Range” Button can be pressed to manually set the range (default mode is auto range). During manual operation, please choose the widest range by pressing the “Range” Button, then choose an appropriate range based on the initial readings. When the “OL.:’ symbol is displayed on the screen, users must choose a wider range to obtain a reading. In Auto Range Mode, a range does not need to be manually set.

- After measurement, turn the rotary switch to the OFF position to turn off the meter.
NOTE:
- Is the diode functioning correctly? If the red test lead is connected to the positive pole of the diode and the black lead is connected thethe negative, then the diode should be in a forward conduction state, and the displayed value is the forward voltage drop.
- Normal diode forward pressure drop: the general silicon tube is 0.5-0.7 V, the germanium tube is 0.15-0.3 V.
- Polarity Judgment Method:
- Switch the multimeter to the Resistance setting.
- Connect the two test leads to the two electrodes of the diode.
- Measure one result, then swap the positions of the test leads, then measure the second result.
- The larger result is the reverse resistance, and the smaller result is the forward resistance. The smaller resistance is when the black test lead is connected to the positive end of the diode and the red lead is connected to the negative end.
