Because the display part is easy to see and operability is good, we have patronized for many years. It is compact and lightweight, so I always carry it while I work. In general, the digital tester is harder to understand the voltage change in a very short time compared with the analog, but since this product has a bar graph display, if there is a signal line of the air conditioner, the presence or absence of the signal is judged by the motion of the graph I can do it. The continuity test buzzer sound is also convenient and will be used frequently. Until now, there is no experience with the main body failure. Battery replacement is once a year or not. (Caution of lid screw is lost.) If you use it for a long time, there are breakage of the notebook case and rupture of the lead wire. The case can be repaired with repair tape etc, but since the breakage of the lead wire (including internal disconnection) is not replaceable, I think that it is time for replacement.
