DMM This chapter introduces the multimeter function. Interface The measuring types include DC voltage (V, mV), AC voltage, DC current (A, mA), AC current (A, mA), resistance, capacitance, diode, and on-off test. Measurement 1. DC and AC voltage measurement a) Press the power button to turn on, then press the "DMM" button to enter to the multimeter function interface; b) Press the up, down, left and right direction keys or F1, F2, F3, F4 multi-function keys to select "DC V", "DC mV" or "AC V"; c) Insert the black pen into the input port of the COM banana socket, and insert the red pen into the input port of the V/Ω/C banana port; d) Connect the red and black forms to the measured point.
The voltage value of the measured point will be displayed on the screen. 19
