Multiple Measurements
With the multiple measurements functionality, you are able to record multiple measured values during the value recording process. The inspection result for the measurement is determined based on whether the values are within the tolerances or not.
Setup
In the Test Property Card, choose Show more in the General FastTab to access the two fields that define if and how multiple recordings are used:
- Multiple Recording - activates the multiple recording feature for the test property.
- Multi Rec. Calculation Type - specifies the type of calculation that will be used for consolidating the multiple recordings into one determined value.
Multiple Recording Calculation Types
The Multi Rec. Calculation Type options, along with valid Result Types, are described in the following table.
| Multi Rec. Calculation Type | Valid Result Type | Formula |
|---|---|---|
| Min | Integer, Decimal | Calculates and stores the smallest measurement as the final value. |
| Max | Integer, Decimal | Calculates and stores the largest measurement as the final value. |
| Average | Integer, Decimal | Calculates the sum of all measurements, then divides by the total count. NOTE: This is the default for new test properties. |
| Standard Deviation | Integer, Decimal | Calculates the standard deviation of the measurements and stores it as the final value. |
| First Value | Integer, Decimal, Boolean, Option | Uses the first measurement entered as the final value. |
| Latest Value | Integer, Decimal, Boolean, Option | Uses the latest measurement entered as the final value. |
| Mode (Most Frequent Value) | Integer, Decimal, Boolean, Option | Identifies the value that occurs most often. |
| Sum | Integer, Decimal | Stores the total of all measurements as the final value. |
| K. O. Criterion | Boolean, Option | If at least one measurement is negative (for example, "not OK"), the entire test property is considered out of spec or failed. |
Note
After turning on the Multiple Recording toggle and selecting an option in the Multi Rec. Calculation Type field in an existing Test Property Card, run the Update Test Plans action to update this setting in the related Test Plans (see Mass Updates of Test Plans).
Examples of Calculation Types = Average and Mode (Most Frequent Value)
The following table provides examples of using the default Calculation Type of "Average" for Decimals/Integers and "Mode (Most Frequent Value)" for Booleans/Options. The results for Options depend on whether there are two or more than two options.
| Calculation Type | Result Type | Description | Example |
|---|---|---|---|
| Average | Decimal / Integer | Total value of the measurement is calculated using the average of all entered values. | Four lines with values "100", "103", "105", and "100" will result in Determined Value = "102". |
| Mode (Most Frequent Value) | Boolean | Each entered result (measurement) will be verified against the Expected Value and then the Determined Value of the Test Order Test Property will reflect the value of the majority (50%+1) of the recorded measurements. | Four lines with "Y" and five lines with "N" will result in Determined Value = "N". |
| Mode (Most Frequent Value) | Option (two options) | Each entered result (measurement) will be verified against the Expected Value. It then follows the same logic as Boolean in which the Determined Value of the Test Order Test Property will reflect the value of the majority (50%+1) of the recorded measurements. |
Four lines with "OK" and five lines with "OOS" will result in Determined Value = "OOS". |
| Mode (Most Frequent Value) | Option (more than two options) | Each entered result (measurement) will be verified against the Expected Value. If the majority of the recorded measurements meet the Expected Value of the Test Order Test Property, this value will be assigned as the Determined Value. Otherwise, the Determined Value will remain empty. |
The Expected Value is "RED". - If the recorded measurements are: three "RED", one "GREEN", and one "BLUE", then the Determined Value = "RED". - If the recorded measurements are: two "RED", three "GREEN", and one "BLUE", then the Determined Value is empty. |
Value Recording
In the standard process for recording measurements, you enter the measured value in the Determined Value field in one of the value recording pages (QA Value Recording, Test Order/Value Recording Card, and Value Recording Worksheet) and then continue to the next measurement.
The process for test properties that have the Multiple Recording toggle turned on is that the measured values are entered in the Test Order Measurements page, which can be opened by:
- entering a value in the Determined Value field – the page opens with this value as the first entry
- choosing the No value in the Multiple Measurement Exists field – the page opens with minimal information where you can begin the process by entering the first measured value
The fields on the Test Order Measurements page are described in the following table.
| Field | Description |
|---|---|
| Entry No. | Indicates the entry number of the measured value. |
| Test Property Code | Indicates the test property code of the measured value. |
| Measured Value | Indicates the measured value. |
| Lower Limit | Indicates the lower limit of the acceptable tolerance. |
| Upper Limit | Indicates the upper limit of the acceptable tolerance. |
| Expected Value | Indicates the value expected for this test property. |
| Valid Determined Value | Indicates whether the measured value is within the acceptable tolerance. |
| Created By / Created At / Modified By / Modified At | Specifies the user ID and date/time the entry was created and modified. |
When the Test Order Measurements page is closed, the recorded values are calculated and entered in the Determined Value field as described above. If the value is within the tolerance, the Valid Determined Value toggle is turned on; otherwise, the toggle remains turned off.
The Property Tested field is not set automatically for lines with multiple measurements because the number of needed values is unknown. Therefore, you must manually set the property as tested.
To enter multiple measurements
Create a test order with test properties that allow multiple measurements.
Begin the value recording process from the Test Order Card, Test Order/Value Recording Card, or Value Recording Worksheet.
For the line with the test property for multiple measurements, enter the first value in the Determined Value field or choose the No value in the Multiple Measurement Exists field.
The Test Order Measurements page opens either with the first entry populated or with no values, respectively.In the Measured Value field, enter the measured value.
Go to the next line and enter the next measured value.
Repeat step 5 for all measured values.
Choose the Close button when all values are entered. The results are:
- The Multiple Measurement Exists field is set to Yes.
- The Determined Value and Output Value fields are populated with the measured values as described above.
- The Valid Determined Value toggle is turned on if the value is within the tolerance or is turned off if not.
Set the test property as tested:
- In the QA Value Recording page, choose the Tested action on the New menu.
- In the Test Order/Value Recording Card or Value Recording Worksheet page, select the Property Tested checkbox on the line.
Continue with processing the other lines with or without multiple measurements to finish the test order.
To view multiple measurements in test order
Multiple measurements entered in a Test Order line can be viewed in the Testing Finished or Finished Test Order by choosing Test Property Set > Card from the Lines FastTab. In the Test Order Prop. Set Card (M) page, choose the Yes value in the Multiple Measurement Exists field. The fields on the Test Order Measurements page are described above.
