Introductions:
This instrument is a portable, LCD-driven digital multimeter. It has the functions of measuring AC current, DC current, AC voltage, DC voltage, resistance, capacitance, NCV, etc.
It also has the functions of reading retention and night backlight. It is an ideal tool for electricians, technicians, maintenance personnel and amateurs.

Product description:
-Easy to use. This product is a battery-driven automatic range digital multimeter with true RMS.
-Digital display. LCD display, backlight display, clear reading.
-Multimeter. Voltage, current, resistance, capacitance, diode, non-contact voltage detection can be used.
-Automatic shutdown. The multimeter will shut down automatically after 15 minutes.
-LED lighting. With LED beads, it can be illuminated at night.

Special note: Digital Multimeter in millivolt gear, numerical jump is the correct phenomenon.
Multimeter mV file display is not zero phenomenon, mainly the following circumstances:
-The excessive changes of ambient temperature and humidity in the air lead to the phenomenon of no return to zero.
-There is strong electric field or magnetic field interference around.
-The multimeter itself is out of order.
When the multimeter does not return to zero, it can be judged as follows: the multimeter is set to the mV file, the corresponding input hole is inserted into the red-black table pen line, and the red-black table pen line is shortened. At this time, the multimeter shows that "0000" can judge that the phenomenon of non-return to zero of the multimeter is due to environmental factors, which do not affect the use of the multimeter, but it is suggested to eliminate environmental interference factors. In order to avoid affecting the measurement accuracy and producing erroneous measurement results.
