Review: Handy thing to have - Bought to test my meter periodically a while back. Great bit of kit but a bit on the expensive side. Having said that what's cheap when it comes to test equipment. Good to have in the bag. The meter has been out of calibration since 2018. Still very close to the reading it is supposed to be. Handy as a way of checking if in doubt.
