Portable multimeter M838 Mastech 13-2004

Multimeter is an electrical measuring instrument that includes several functions and a set of measurable parameters. All M838 series devices measure DC and AC voltage, DC current, circuit resistance, and even temperature. Additionally, this device can be used for diode testing. Another distinguishing feature of this device is the square wave generation function (square wave), which is required for signal measurement and conversion in other fields. The M838 device is a portable multimeter; its compact size allows it to be carried with you at all times. However, despite its small size, this multimeter possesses wide functionality, which distinguishes it advantageously from others. Engineers have strived to make the device as convenient as possible for use. The selection of measured quantities and measurement ranges is performed using a reinforced rotary selector, which eliminates the possibility of accidental pressing. The device is made of high-quality materials. Calibration and testing of the devices were performed under the control of the SDS company.
