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 f.s."
or "counts" or "ohms" remain constant. |
