Factory default setting is “2000” microns.
The default values are listed in microns, however values will be displayed in the current units selected. For
example, if the user defined Unit Selection setting is Pascals, units displayed will be: 7, 14, 33, 66, 133, 166,
200, and 266 (The Pascal conversion of the 50 – 2000 micron values).
The “ALARM”, “HIGH” icon will be displayed to indicate you are setting up the High Limit Alarm.

High Limit Alarm
MODE and SCROLL UP buttons will enable the High Limit Alarm ONLY IF the existing pressure is below the
preset, user defined High Alarm setting. If the existing pressure is higher than the preset, user defined High
Alarm Limit, the High Limit Alarm cannot be enabled. If the Low Limit Alarm is currently enabled, setting the
High Limit Alarm will disable the Low Limit Alarm even if the High Limit Alarm fails due to pressure readings
above the High Limit Alarm setting. An enabled High Limit Alarm will display the “HIGH”, “ALARM” icon on
the main display screen, and will disable the Low Alarm setting.
If High Limit Alarm is enabled and the pressure is greater than or equal to the preset, user defined High Alarm
setting limit value, the alarm will alert with a beep sound every second and the “ALARM”, “HIGH” icon will
flash. Beeping and flashing will continue even if the pressure drops below the High Limit Alarm setting. Press
any button to turn off the alarm.
Button-press Feedback (BEEP)
Key-press feedback determines whether an audible sound is heard each time a button is pressed.
Available settings are: ON, OFF. Factory default setting is “ON”.
To change the selection, use the SCROLL UP or SCROLL DOWN button. To cancel, press the POWER button.
To select and store the setting shown, press the MODE button. When a setting is stored, you will be returned to
main menu selections. Press POWER to return to normal operation mode.
Display Resolution (HI RES)
The display resolution menu allows you to select whether pressure will be shown at high resolution. High
resolution means that pressure is shown as-is, in one unit increments.
Available settings are: ON, OFF. Factory default setting is “OFF”.
When the setting is OFF, the reading display is rounded.
To change the selection, use the SCROLL UP or SCROLL DOWN button.
To cancel, press the POWER button.
To select and store the setting shown, press the MODE button. When a setting is stored, you will be returned to
main menu selections. Press POWER to return to normal operation mode.
Note: Even if high resolution display is ON, pressure values above 1000 microns will be rounded off according
to the current display pressure.
