This technology is extremely important for individuals who diagnose HVAC applications, electronic ballasts, PC circuits, and much more.
Auto power off
Busy electricians can at times forget to switch off the device and this may lead to some dangers. But with this unit, you can rest assured that it will turn itself off after 15-minutes of inactivity. This feature not only saves battery power, but it also saves time and money.
