What measurement can I use to calibrate the valve lash on a Honda accord 96 lx?

Your question is unclear. Valve lash is not "calibrated", it's adjusted, and the specs are on a sticker on the underside of the hood. If your sticker is missing, look it up or buy a service manual - if that's what you're asking.
