Product review (1 stars): review for the amprobe TH-1
The first one did not respond when I installed the battery. No display....nothing. The second one also did absolutely nothing. The THIRD one did absolutely when installing the battery. Alll the batteries, (3 volts), were good.....(3.255 volts to 3.256 volts). All three of the TH-1's were defective and did nothing when energized. The displays did not turn on or even blink!
