| 90 day specifications |
The standard specification intervals for the 741B is 1 and 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 full scale" or "counts" or "ohms"
remain constant. |
