(3) Alarm Output
Alarm On
Disabled - The alarm output is disabled and will not operate.
Rising - The alarm output activates ONLY when the pressure meets or exceeds
the High Setpoint.
Falling - The alarm output activates ONLY when the pressure meets or falls
below the Low Setpoint.
Rising & Falling - The alarm output activates when either the pressure meets or
exceeds the High Setpoint OR the pressure falls below the Low Setpoint.
HAL (High Alarm Limit) Setpoint
Here you set the high value at which you want the alarm to activate.
LAL (Low Alarm Limit) Setpoint
Here you set the low value at which you want the alarm to activate.
Alarm Deadband
Deadband is an area where no action occurs. The purpose is to prevent
oscillation or repeated activation-deactivation cycles. The deadband value is
expressed as a percentage of the full scale range of the meter. If your process
value will always be very close to your alarm setting you should adjust the
deadband to be a small percentage of the full scale range.

(4) Analog Output Options

Mode
Select the type of analog output your application requires. You can leave the
default setting if you will not be using the analog output feature.
Process Units
The unit supports 6 standard process units: PSI, in-H20, in-Hg, hPa, bar, and mbar.
The unit may be configured for additional process units by using the Custom
Units option. Checking the Custom Units checkbox allows the user to enter a three
character label and the conversion factor for a custom process unit. The conversion
factor is based on the value required to convert PSI to the custom unit.
(5) Sensor Options
Sample Interval
Here you can set how often the device samples the sensor and updates the LCD.
3-11
The sample interval is always fixed at 0.382 seconds/sample
(2.6 samples/second) when powered externally, regardless
of the setting in the Configuration Wizard. The purpose of
the sample interval setting is for conserving battery life, not
for display damping or averaging, and therefore has no
effect unless operating on battery power only.
