How To Use<\/div>\n

How To Use<\/h2>\n

DM202 is designed for quick operation. Use the correct input jack, keep the measurement within the rated range, and follow the manual when testing unknown or live circuits.<\/p>\n <\/div>\n

\n
\n

Power On<\/h3>\n

Hold the power button for 2 seconds to turn the device on. The meter can automatically shut down after 15 minutes without measurement.<\/p>\n <\/article>\n

\n

Insert The Test Leads<\/h3>\n

Connect the black lead to COM and use the correct jack for current, voltage, resistance, or continuity according to the test you need.<\/p>\n <\/article>\n

\n

Let Auto Mode Identify<\/h3>\n

In auto mode, the device identifies AC\/DC voltage, resistance, or continuity, helping reduce manual setup.<\/p>\n <\/article>\n

\n

Read Or Hold The Value<\/h3>\n

Read the 4000-count LCD directly, or press the hold\/backlight button briefly to lock the current measurement value on the screen.<\/p>\n <\/article>\n

\n

Use NCV For Quick Detection<\/h3>\n

Hold the NCV button and bring the meter close to the wire to detect AC voltage. Release the button to exit NCV mode.<\/p>\n <\/article>\n <\/div>\n
