General

This instrument is a compact pocket- sized 3 ½
digital multimeters for measuring DC and AC
Voltage, DC Current, Resistance and Diode,
transistor measurement. Low battery voltage
indication is provided. It’s ideal instruments for
use in fields, such as laboratory, workshop,
DIYers and home applications.
