| Data Storage Capacity |
1 week of calibration results |
| 90 day specifications |
The standard specification intervals for the 744 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. |
