Pass Code Entry
A pass code is required to calibrate and configure the gauge.
Additional levels of security may be enabled by defining separate
pass codes for calibration, user configuration, and output test and
set point adjust modes. See Changing the User-Defined Pass Code
at the end of this manual to change pass codes.

condition occurs, the LED for that alarm will begin to blink red and will
continue to blink red until it has been manually acknowledged or until
the alarm condition clears. If an alarm is manually acknowledged, the
LED will be steadily red while the alarm condition continues to exist.
The LED will be steadily green whenever no alarm condition exists.
If M_ACK is selected, an alarm condition must be manually
acknowledged. When an alarm condition occurs, the LED for that
alarm will blink red if the alarm condition exists or green if the alarm
condition no longer exists. The LED will continue to blink until it has
been manually acknowledged by a pressing the TEST button. Once
an alarm has been acknowledged, the LED will be steadily red while
the alarm condition exists or green when the alarm no longer exists.
If NO_AN is selected, the LEDs will not blink. When an alarm condi-
tion occurs, the LED associated with that alarm will be illuminated
steadily red if the alarm condition exists or green if the alarm condi-
tion no longer exists. In addition, the LCD display for ALARM1 and
