Product Usage Instructions

Voltage Measurement
To measure DC voltage, select the appropriate voltage range on the rotary switch. Connect the positive input jack to the positive terminal of the circuit under test and the COM jack to the negative terminal. Read the voltage value displayed on the LCD.

Current Measurement
To measure DC current, set the rotary switch to the desired current range. Connect the current leads in series with the circuit being measured. Ensure not to exceed the maximum input current for accurate readings.

Resistance Measurement
Select the resistance range on the rotary switch. Connect the test leads to the component or circuit under test. The meter will display the resistance value in ohms.

Temperature Measurement (DMM-8301A only)
To measure temperature, press the corresponding function button and use the built-in temperature measurement feature. No separate instruments are needed for this function.
