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.

Essential for testing and confirming low ohms and IR tests.
Used this to calibrate my Kewtech KT65-DL mft. Works a treat, reassures your testing especially on low ohms ranges, and insulation testing. Guarantees repetitive readings. Ok it's not as comprehensive as a proper calibration from a specialist company, but it's a great second best.
