Calculated Test
The calculated test is performed in tests with charts of type:
| • | IND |
| • | XBR |
| • | XBS |
| • | XMR |
| • | HIS |
Such charts' addition method is described in the Product Specification Registry, but it is worth noting:
| 1. | Always use the same chart for the tests involved in the operations, calculated as well as used in the formula, as in the following example: |

|

Test 2 |
|

XBR |
Test 3 |
Measurement Sum Test 1 and Test 2 |

XBR |
| 2. | When using tests with chart types XBR, XBS etc., you can define the number of measurements and, when using calculated test, the number of measurements of all tests involved in the calculation, besides the calculated test itself. Thus, they must be equal, as in following example: |
Wrong |
||||
Test 1 |
|
4 Measurements |
Typed |
XBR |
Test 2 |
|
5 Measurements |

The calculations are performed per column (measurement), according to the number of measurements defined in Test Registry. For Root, ABS, Average, and Deviation type operations, you cannot perform operations with more than one test. Example: Deviation (Test 1) + Deviation (Test 2) - in this type of operation no calculation is performed. |
