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).

Equipment Calibration Frequency

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.

Special Frequencies

"Month of" Example

  • Frequency:  Month of
  • Last Calibration:  04/27/2019
  • Units:  12
  • Offset:  Next
  • Calibration Due:  04/27/2020
  • Label Display:  Due Month of Apr-2020 *

How the math works . . .

  1. Calculate 12 Months after Last Calibration, which yields 04/27/2020
  2. The Offset is set to Next [Month] so the Due Month jumps to the next Month, which yields 05/1/2020

"Week of" Example

  • Frequency:  Week of
  • Last Calibration:  06/01/2019
  • Units:  30
  • Offset:  Next
  • First Day of Week:  Monday
  • Calibration Due:  07/01/2019
  • Label Display:  Due Week of 07/01/19 *

How the math works . . .

  1. Calculate 4 Weeks after the Last Calibration, which results in 06/29/2019.
  2. Since the Offset is set to Current [Week] and the First Day of Week is set to Monday, the Monday of the current week results in a due week starting on 07/01/2019.

* “Month of” and “Week of” Date Masks

Edit Date Masks from the 'Labels' tab of the Options dialog to modify preferences for how Due Dates display on data grids, dialogs, and labels.

Example:  The default “Month of” mask is MMM-yyyy, which results in "Month of Apr 2020".  The default "Week of" mask is MM/dd/yy, which yields "Week of 04/01/20".  Use the combo boxes to select other pre-defined date masks or create your own.

Note that placing the letter 'u' at the end of any date mask will cause all letters in the mask to display in upper case.

Remember:

  • MASK:  When a curser is not in control.
  • FORMAT:  When curser is in control (EDIT mode).

and

  • DATETIME:  Controls that show date and time.
  • DATE:  Controls that show only date.
Date Masks

Date/Time Masks & Formats for Grids

Select the preferred masks and formats from the combo-box drop-down options.

Date/Time Masks & Formats for Grids

The Date Mask field controls how the date displays when activated with the cursor (e.g., clicked on).

Date/Mask Field for Grids

Date/Mask Field - Example

The Date Format field controls how the date displays when the field is not selected (e.g., without active curser).

Date Format for Grids

Date Format Field - Example

The Date/Time Mask field controls how the date displays in a sub-panel grid when pointed to with the cursor (selected without editing), (e.g., only a single mouse click).

Date/Time for Grids

Date/Time Mask Field Example

The Date/Time Format field controls how the date and time field in a sub-panel grid displays when not selected (e.g., without active curser).

Label Date Masks

The Standard Mask field controls how the date displays on most labels where a "Month of..." and "Week of..." mask is not applied.

Standard Mask for Labels

The Month of Mask field controls how the date displays when a Label has a "Month of..." mask applied.

Month of Mask for Labels

The Week of Date Mask field controls how the date displays when a Label has a "Week of..." mask applied.

Week of Date Mask for Labels

Custom Frequencies

Unfortunately, users are not able to add or remove frequencies because code exists within the software to perform date calculations based on the frequency chosen.  If you believe a special frequency is needed that is not already in the table, let us know.  It's possible that the frequency is already there under a different name.  If the frequency you need is not there, maybe we can add it for you.
