Digital multimeters are the multi-purpose electronic measuring instrument, voltage meter, ammeter, including general ohmmeter and other functions.
A digital multimeter has a portable device for basic fault diagnosis, and also a device placed on a workbench, with a resolution of seven or eight bits.
The characteristics of Digital Multimeter in safety:
1, insurance tube current input protection.
2, use high energy insurance (600 volts or higher).
3, high voltage protection in resistive mode (500 volts or higher).
4, voltage transient protection (6000 volts or higher).
5, the safety design of the test lead what is, what is the digital multimeter safety handle, etc.
6, independent security certification.
