Configuration Mode
NOTE:
For flowchart view of Configuration Mode, see pages 6 and 7.
Introduction
The configuration mode is used to change or set several options, as well as to zero
and calibrate the instrument. Gas alarm indications will occur in configuration
mode, with two exceptions: no alarms will occur during the zeroing/calibration
process, and gas alarms will not cause the menu flow to jump back to the Gas
Monitoring screen. The configuration screen is reached from the normal operating
screen by holding both buttons for three seconds at the Gas Monitoring screen.
Once in configuration mode, if the Mode and Enter buttons are both held for 3
seconds, the instrument will exit the configuration screen and return to the Gas
Monitoring screen. In addition, from anywhere within the configuration screens
(except during zeroing and calibration), the instrument will return to the Gas
Monitoring screen if no buttons are pressed for 30 seconds.
Security Code
The Security Code screen is the first screen in the configuration mode. The default
security code is 000. If this is the stored value of the security code, the instrument
bypasses this screen and displays the Zero Initiate screen.
On entering the Enter Security Code
screen, the primary character display
will show the number ‘000’. All
characters of the primary display will
blink to indicate that they are ready to
change. Enter the security code by
pressing the Enter button. Momentary
presses of the Enter button will
increment the security code by one
count. Holding the Enter button for an
extended period will activate an
accelerated number increment.
Enter Security Code Screen
Once the correct code is reached, pressing the Mode button will navigate to the
next configuration screen which is the Zero Initiate (or, for O2 sensors, Cal Initiate)
screen. If the Mode button is pressed while the wrong code is displayed, the
instrument will leave the configuration screen and return to the Gas Monitoring
screen.
