Calibration Frequencies
Quick Start Video
Watch a short video to learn about Calibration Frequencies in Calibration Control (our Calibration Management Software) and how they work.
How do Calibration Frequencies Work?
Calibration Frequency is the interval of time between required calibrations of any given piece of test equipment. Set the Calibration Frequency of Equipment in the Calibrations tab of the Equipment dialog (below).
Calibration Fields
There are four fields involved in the Calibration Frequency function. They are:
- Last [Calibration]: Date of the last calibration.
- [Calibration] Frequency: How often the Equipment is calibrated.
- Units: Calculates the frequency automatically based on the unit selected. The Unit field is disabled with Frequencies like Yearly or Monthly because they have an inherent Unit value.
- Next [Calibration]: Due date of the next required Calibration.
Calibration Frequencies
The following are all the Calibration Frequencies in Calibration Control where 'n' is the number value in the Units field.
| Frequency Name | Frequency Description |
| Biennial | Every 2 years |
| Bi-Monthly | Every 2 Months |
| Bi-Weekly | Every 2 Weeks |
| Cal Not Required | No Due Date . . . Not Calibrated |
| Daily | Every Day |
| Days | Every n Days |
| Manual | Set the Next Calibration (Due Date) manually |
| Month End | Every n Months due on the last day of the month |
| Month of | Every n Months due at any day within the calculated month |
| Month Start | Every n Months due on the first day of the month |
| Monthly | Every Month |
| Months | Every n Months |
| Next Use | No Due Date . . . Next Use |
| Not Calibrated | No Due Date . . . Not Calibrated |
| Quarterly | Every 3 Months |
| Reference Only | No Due Date . . . Reference Only |
| Semi-Annual | Every 6 Months |
| Undefined | No Frequency Defined |
| Use Count | Calibrate every n uses where n = Units. Use the Check In/Out dialog to automatically increment uses. |
| Use Days | Calibrate every n days where n = Units. Use the Check In/Out dialog to automatically increment uses. |
| Week of | Every n Weeks due at any day within the calculated week |
| Weekly | Every Week |
| Weeks | Every n Weeks |
| Yearly | Every Year |
| Years | Every n Years |
“Month of” and “Week of” Frequencies
Unlike the other Frequencies that calculate due dates on specific days, the "Month of" and "Week of" are special Frequencies that calculate the month or week a calibration is due. These Frequencies are also affected by two settings in the Options dialog for "First Day of Week" and "Due Date 'Week/Month of' Offset". By default, the "First Day of Week" is set to whatever is standard on your operating system. The default for the Offset is the Next Month or Week after the calculated due date.
