90 Day Specifications	The standard specification interval for the 743B is 1 or 2 years. Typical 90 day measurement and source accuracy can be estimated by dividing the one year "% of reading" or "% of output" specifications by 2. Floor specifications, expressed as "% of f.s.", "counts" or "ohms", remain constant.
