# GRR Measurement

This screen gives you a facility to capture the readings for an Instrument both Manually and Automatically. You can take simultaneous readings for all the parameters mapped to an instrument. Details of the Channel No., Serial/Parallel Port, and Port No. for the Instrument are also provided.

Reading Mode and Station No. are displayed from the Gauge R & R Mapping screen. The current user is displayed as the Operator Code.

For Manual Reading Mode, the Operator Code is used to identify by whom the readings were taken. Channel No. and Port Details (whether Serial Port or Parallel Port, Port No.) are not defined.

For Automatic Reading Mode, whether Serial Port or Parallel Port is displayed from the Interface master of the Instrument. Port No. and Channel No. are displayed from the Instrument master.

A grid is provided for taking readings. The first column displays Part numbers from 1 to ‘n’, where ‘n’ is the number of parts specified in the Gauge R & R Mapping screen. The balance column/s of the grid are for readings. The number of columns for readings is equal to the number of parameters mapped to the instrument. The readings columns display the parameter names as the headings. e.g. If for the Dumore instrument, 3 parameters ID1, ID2, ID3 are mapped in the Gauge R & R Mapping screen, then the Gauge R & R Measurement screen is launched with the provision of three column for the reading values. The reading value column headers have names as ID1, ID2, and ID3 respectively.

Click Modify to make changes. You can modify Channel No., whether Serial Port or Parallel Port and Port No. only if the reading mode is Automatic.

# Taking Measurements

At a given time, only as many operators may log on as are specified in the Gauge R & R Mapping screen. An operator may take only as many trials as are specified in the Gauge R & R Mapping screen.

In Manual mode, you can enter readings directly into the grid for a particular part and parameter. You can modify readings only until they are saved.

In Automatic mode, select the Part No. for which you wish to take the reading by clicking on the corresponding row. Click Start. A question is displayed whether to proceed with readings. On confirmation, the reading is displayed on the respective parameter cell corresponding to the selected Part No. when you press the switch on the instrument. Repeat the same steps for the other parts. Readings displayed in this way cannot be modified.

Click Save to save readings after all readings for all parts and parameters have been taken. You cannot save only a part of the readings. A reading cannot be modified once it is saved.

Click Close to return to Gauge R & R Mapping screen. The Last Trial Date, Last Trial Time and Trials Done are updated for the parameter(s) for which the trial was taken.
