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. |
