EDC/Krohn-Hite MV216A DC voltage standard teardown and Tempco measurement

Kerry Wong did a teardown of the Electronic Development Corporation’s (acquired by Krohn-Hite) MV216A battery/external powred DC voltage standard:

In this blog post, we are going to take a look at Electronic Development Corporation’s (EDC, acquired by Krohn-Hite in 1998) MV216A battery/external powered DC voltage standard and also measure its voltage reference’s temperature coefficient (tempco). A teardown video is also included towards the end. MV216A is a six decade precision DC voltage standard, it can output from 0.1µV in 100mV range all the way up to 11.1111V in 10V range. Voltage standards of this caliber are usually used as calibrators to calibrate multimeters and other test instruments.

More details at Kerry Wong’s blog.

Check out the video after the break.
