		Meter setting	Description and use
		Waveform	Select the waveform recording time. Use the shortest time to see details in the
		recording time	waveform. If you use a longer time, you lose details in the waveform. This setting
			doesn't influence on the accuracy.
		Waveform type	This is the waveform type for the X-ray generator. It is normally HF/DC. Sometimes
			for older X-ray units and for dental you must use 1-phase. Be careful to select the
			correct waveform type for maximum accuracy.
		Added filtration	Any added filtration specified here will be used to compensate the kV and dose
		(mammography	readings. Use this, for example, when you add filtration during an HVL
		only)	measurement.
			Note: Piranha gives you HVL for each exposure. Use of additional filters is optional.
		Compression	Select here if compression paddle is used or not used.
		paddle
		(mammography
		only)
		Trigger level	This is the level used for the time measurement. You can use this if you want for
		(time)	example to avoid pre-pulses to be included in the exposure time.

There are three different measuring modes available using the Piranha. They are as follows:

 

	Measuring mode	Description and use
	Normal	The Normal mode is used for short and long (fluoro) exposures. In this mode, your
		meter will automatically sense if there is a signal and when it is above a certain
		trigger level. If the exposure is long, the displays/grid will be updated with new
		data every 2 seconds. If the exposure is short, the results are displayed as soon as
		the trigger is off.
	Free run	The free run mode has no trigger level. As soon as the meter is told to begin
		measuring, it starts to measure even if there is no signal. This measuring mode is
		useful when the signal you want to measure is very low . Free run is recommended
		for light measurements, especially when measuring "ambient" light (when no
		shutter is present).
	Timed	The Timed mode setting measures during a pre-defined time period.
		Measurements in Timed mode must be started manually. This measuring mode is
		very useful when you want to measure a very low signal. You can use the "very
		high" sensitivity setting in Timed mode and it will further improve the meter's
		capability to measure very low signals.

 

 

You can read more about meter settings for Piranha in the topics Meter Adjust and Different measuring modes.

 

 

5. Applications with analysis
7. There are also a number of applications available in Quick Check. An application is a predefined measurement where your data are analyzed, it might also include pass/fail criteria. The applications available in Quick Check are not possible to modify in any way. If you have more needs, use Ocean Professional. You can then create tests with user-defined calculations and pass/fail criteria. You will find applications for:

9. Accuracy Reproducibility mA linearity HVL

11. CTDI

14. 1. You start an application by clicking on the Application button (if the button is not enabled, no applications are available for current mode):

21. 2. A menu showing available applications is shown:

3. Chose an application, for example kVp Accuracy. The screen layout is different for the application compared to a standard Quick Check measurement. In this case there are no displays only grid (exposure list) is shown. There is also an analysis that perform some kind of calculation (in this case kVp accuracy) on your measured data.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4. You can modify set values in the grid (exposure list). Click in a cell to change set values. For example, you may want to change the kVp set value for exposure #4 from 80 to 81 kV.

 

 

 

 

 

 

 

 

 

 

 

 

5. Now make the exposures.

You can maximize/minimize the exposure list section and the analysis section with double-click or by clicking on the button.

 

The analysis part will now show the result.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

6. Click on Preview/Print to print your report.

 

 

This analysis is fixed and you can not change its structure. If you have more needs and want to customize your analysis, change pass/fail criteria, use your own calculations and so on; then use Ocean 2014 Professional. The topic Analysis (Definitions) describes which analysis that are available in Ocean 2014.

 

You can open any Quick Check measurement as a Real-time display and in that way modify and extend its capability. See topic Open an old measurement.

 

 

6. Quick Check Favorites
8. The Favorites function in Quick Check is an optional way for you to customize the use of Quick Check. It allows you to use and quickly access templates that performs specific measurements. You use Ocean 2014's template design functions to create your own templates and you store them in a specific folder to make them available in Quick Check.

By default, no Favorites are available in Quick Check. You can create your own Favorites to be used in Quick Check by using Ocean 2014's template design capability. The section Create Quick Check Favorites describes how this is done.

 

If you have stored one or more favorites in the Favorite folder (in the Library) the Favorite list is shown when you start Quick Check. The list shows the Favorites you have stored in the folder.

 

 

 

 

 

 

 

 

 

 

 

 

In this case are two favorites stored in the Favorites folder. If you select one, it loads and you can start to measure directly. If you click on "More...", the normal Quick Check setup procedure starts.

 

 

You can go to the Favorite list whenever you are using the Quick Check by clicking on the Favorites button.

 

 

 

 

 

 

The Favorite list will be shown and you can quickly select a another favorite.

1. Detector selection
3. When you load a Favorite the required detectors are checked when it loads. If a detector specified, or a compatible one, isn't available in the template, the Detector Selection window is shown. It will shown available detectors. It will be directly shown if you disconnect/connect a detector.
