Very disappointed that the voltmeter's accuracy is so poor. With several high quality digital multimeters, I compared this device's readings to theirs. They all read within 0.1 V, except for this product, which consistently reads 5 volts less than the actual voltage. I tested it from 80 to 135 VAC with a variac. It reads about 4.6 V low at 80, to 5.5 V low at 135. I would easily accept +/- one digit and 1%, which would be as much as 2.3 volts high or low, but 5 V low is too much error. Even my cheap $10 VOM is more accurate.
