Digital Multimeters CD771
Feature
- The entire outer surface of the case has been formed with thermo plastic elastomer, giving the main body high resistance against the shock of a drop.
- A backlight is provided to allow the user to read the value displayed even in dark locations.
- The continuity check enables the user to verify electric continuity through both the buzzer sound and the LED illumination.
- The 1.5V battery check function is available, allowing you to quickly check battery power.
- A fuse of large breaking capacity is used to further improve safety.
- A safety cap is provided for current measurement. Maximum 20A can be measured if the measurement time is less than 10 sec.
