Best Xmas ever! shouted the wife as she unwrapped her AC millivoltmeter.
The LWDQGS TVT-321 arrived today. The packaging was excellent. The shipping speed was very fast. Communications with the seller were good. The only question was the line voltage. My lab is fitted with a 120V to 220V transformer so I accepted the 220V version. The TVT-321 is very easy to use and the calibration was within specifications. The meter has a mirror dial to eliminate parallax errors when reading a value. The frequency band extends beyond the audio band to at least 200 KHz (that is as far as my Kikusui low distortion generator goes). I highly recommend the TVT-321 and the seller.
