ST212 enters DCA DC current when it is turned on in AUTO mode and has no test state, and the operation method of returning to zero calibration: 1. Press the power on when the screen is off, and then quickly press the HOLD button for 3 consecutive clicks after the screen lights up (quickly complete the above operations). LCD display HHHH 2. Press the SEL key twice to enter the DC mV file. 3. Continue to press the SEL key → turn to DC V file → resistance KΩ file → nF capacitor file → ℃ temperature file → ACA AC current file → DCA DC current file (press SEL key 6 times to turn to DCA file) 4. In DCA mode, press and hold the HOLD button for 2 seconds, the buzzer ticks once, and the reading is close to zero. 5. After the reading is close to zero, press and hold the power button to turn off the machine to complete the operation, and then turn it on again to test.
