Display Screen Start Up
Press POWER button once to power gauge on. If unit display does not light up, check for correct battery
installation. Startup display will show “JB”, “JUST BETTER”, a loading menu, followed by either the micron
value or the over range indicator “oooooo.”
The center bars in the loading menu move to indicate the unit is in initial warm up state. It may take up to 30
seconds for the unit to go into normal operation mode.
The unit will display “oooooo” when it is at atmospheric pressure, or at a pressure over 100,000 microns. This
indicates an over range condition. When the pressure is at or below 100,000 microns, the gauge will display
the value.
Note: The DV-41 is factory calibrated, field calibration is not required.

Battery Status Indicator
When the startup sequence is complete, the BATTERY STATUS INDICATOR will show current battery life status.
While the unit is on, the status is updated once every second. Battery status indicator is not visible if the DV-41
is connected to external power source (AC adapter).
Battery voltage status is as follows:
When the battery voltage drops below 2.4 volts, the battery outline will flash and the unit will beep once per
minute to alert the low battery condition. When battery voltage falls below 2.1 volts, the shutdown timer is
activated. If voltage stays below 2.1 volts for thirty seconds, the DV-41 will beep once and power off. If power
is restored during this time, shutdown is canceled.

Unit Selection (UNIT)
When the alarm menu is active, a constant pressure value equivalent to 1000 microns is displayed using the
currently selected units (EG: 133.31 for Pascals). The current selection is shown at the top of the main display
screen.
Available unit selections are: Microns, PSIA, inHg, Pascals, Torr, mTorr and mBar.
Factory default setting is “MICRONS”.
To scroll the selection, use the SCROLL UP and SCROLL DOWN buttons.
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.
Low Alarm Setting (AL--LO)
The Low Alarm setting sets the pressure level where an alarm will be sounded. Setting a specific alarm level
selection DOES NOT make the alarm active; it specifies the pressure level BELOW which the alarm will sound
once the user enables the Low Limit Alarm (press MODE and SCROLL DOWN buttons to enable).
Available settings are: 50, 100, 250, 500, 1000, 1250, 1500, or 2000 microns.
Factory default setting is “500” microns.
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”, “LOW” icon will be displayed to indicate you are setting up the Low Limit Alarm.
To scroll the selection, use the SCROLL UP and SCROLL DOWN buttons.
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.
Low Limit Alarm
MODE and SCROLL DOWN buttons enable the Low Limit Alarm.
Low Limit Alarm can be enabled in all cases including when the pressure is in OVER RANGE except for when
the sensor is not connected.
An enabled Low Limit Alarm will display the “LOW”, “ALARM” icon on the main display screen, and will disable
the High Alarm setting.
If Low Limit Alarm is enabled and the pressure is less than or equal to the preset, user defined Low Alarm
setting limit value, the alarm will alert with a beep sound every second and “ALARM”, “LOW” icon will flash.
Beeping and flashing will continue even if the pressure rises above the Low Limit Alarm setting. Press any
button to turn off the alarm.
High Alarm Setting (AL--HI)
The High Alarm setting sets the pressure level where an alarm will be sounded. Setting a specific alarm level
selection DOES NOT make the alarm active; it specifies the pressure level ABOVE which the alarm will sound
once the user enables the High Limit Alarm (press MODE and SCROLL UP buttons to enable).

Available settings are: 50, 100, 250, 500, 1000, 1250, 1500, or 2000 microns.
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.
To scroll the selection, use the SCROLL UP and SCROLL DOWN buttons.
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.
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.
