When the measured voltage exceeds 36Vdcor25Vac, the operator should fully avoid electric shock. Misuse of patterns or changes can lead to image distortion, so when input is within range, OL will be displayed on the screen. Low battery power can lead to incorrect readings. Please change the battery power when the battery power is low.Digital multimeter mV file appears to
be non-zero, mainly in the following cases:1: If the ambient temperature and humidity in the air change too much, it will not return to zero; 2: There is a strong electric field or magnetic field disturbance around. 3: The multimeter itself is faulty. When the multimeter does not return to zero, it can be judged as follows: the multimeter is dialed to the mV file, the corresponding input hole is inserted into the red and black pen
