Configuring System Settings

PULSE allows you to configure the hardware settings through the SYSTEM SETTINGS menu on the Home Screen. There are three tabs in the SYSTEM SETTINGS menu: CYCLE THRESHOLD, DEVICE SETTINGS, and DISPLAY SETTINGS. Each tab includes predefined settings that you can change to meet your preferences.

CYCLE THRESHOLD

The CYCLE THRESHOLD tab allows you to configure the PULSE hardware settings. These settings are used as the default values for all profiles created after changes are saved. The CYCLE THRESHOLD tab includes three subsections, General, Prime, and Recovery, that you can navigate using the up and down arrows on the right side of your screen. These three subsections determine the values used for Dilution cycles, Priming cycles, and Recovery cycles, respectively. Each of these subsections contain the same fields, such as Pressure Source, Vacuum Source, Tube Pressure, and others. You can modify each field option by typing a new value in each of the corresponding fields. See the table below for detailed explanations of each field.

Options	Description
Pressure Source	Determines the pressure source values. It includes the Source On, source Off, Drain On, and Drain Off values.
Vacuum Source	Determines the vacuum source values. It includes the Source On, source Off, Drain On, and Drain Off values.
Tube Pressure	Determines the tube pressure values. It includes the Source On, source Off, Drain On, and Drain Off values.
Source On	Determines the lowest pressure limit for the pump to start pumping to increase pressure.
Source Off	Determines the highest pressure limit for the pump to turn off to reduce pressure.
Drain On	Determines the highest pressure limit for the pump to open the valve when the pressure is much higher than the target pressure.
Drain Off	Determines the pressure limit for the pump to close the valve when the pressure is slightly higher than target pressure.
Diaphragm Timing	Determines the duration of the diaphragm actuation.
Valve Delay	Determines the duration of the valve actuation.
Sequence Timing	Determines the duration of the primary or recovery sequences.

Options	Description
Device ID	The Device ID includes the manufacturing number and hardware type or version.
Device Name	Determines the device name for easier identification when using the PULSE software remotely. Tap the Device Name field, then type a name for your PULSE.
Organization	Determines the name of the device’s organization for easier identification when using the PULSE software remotely. Tap the Organization field, then type the name of your organization.
Device Date and Time Field	Shows the device’s current time zone, date, and time. If you connect the PULSE instrument to the internet, the time zone, date, and time will be updated automatically. You can also update the date and time manually if the instrument is offline.

Options	Description
Font Size	Determines the font size used in the software interface. Select SMALL, MEDIUM, or LARGE.
