# Stability 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 Stability 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, Port settings will be displayed based on the selected and connected instrument. If the instrument is connected to a serial port, then the Serial Port value is displayed as Port No. If the instrument is connected to a parallel port, then the parallel port number and the channel to which instrument is connected will be displayed as Port No. and Channel No. respectively.

A grid is provided for taking readings. The number of columns for readings will be 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 Stability Mapping screen, then the Stability 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.

There will be only one row for the grid since at one trial only one reading can be taken for the mapped parameters.

Enter multiple lines of remarks on the reading taken in the Remarks textbox. The Start button is enabled only when the reading mode is Automatic.

Click Modify to make changes. You can modify Channel No. and Port No. only if the reading mode is Automatic. If the Interface for the instrument selected in the study has serial port settings, then you can modify only Port No. If the interface for the instrument selected has parallel port settings, then you can modify only Channel No.

# Taking Measurements

In Manual mode, you can enter readings directly into the grid for the parameters in the respective columns. You can modify readings only until they are saved.

In Automatic mode, select the row in the grid. Click Start. The readings are displayed in the respective parameter cells when you press the switch on the instrument. They are displayed with appropriate decimals places that are set to each parameter while mapping. Readings displayed in this way cannot be modified.

After the readings are entered or displayed, you can enter Remarks about the readings taken.

Click Cancel to cancel all the readings and remarks displayed and you can take readings afresh.

Click Save to save readings after all readings for all 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 Stability Mapping screen. The Last Trial Date, Last Trial Time and Trials Done are updated for the parameter(s) for which the trial was taken.
