To calibrate my whole equipment, I only drive to work!

For voltage reference, I use a module I bought on eBay for $20 US. Just search eBay for "voltage reference ad584" (without the quotes) and you will get many examples. Some use the AD584L chip which is laser trimmed to +/- 5 mVolts which is good enough for most of us. Mine came with a hand written "final value" paper that gave the values to 5 digits.
If you want a step up, check out Low Cost Precision Voltage References . This seller offers several great references from simple DC voltage up to voltage (AC and DC), resistance, current, and frequency for $80 US.

Subject: [TekScopes] Multimeter Calibration and Voltage Referance

It would be interesting to know how members go about and keep in check accuracy of their workshop multimeters. I have 5 multimeters and each is giving slightly different results. It would be nice to calibrate them to a known voltage standard.


Of course I could pay the money and have them calibrated with the certificate but I am just wondering if there is an easy home made method to address this.
