5.6 Security Access
5.6.1 How the Security Code Works
When entering the correct access code for the
Calibration/Hold security level, the Calibration and
Hold menus are accessible. This allows operators or
technicians to perform routine maintenance. This
security level does not allow access to the Program or
Display menus.
When entering the correct access code for All security
level, the user has access to all menu functions, includ-
ing Programming, Calibration, Hold and Display.
5.6.2 Procedure
1. If a security code has been programmed, selecting
the Calibrate, Hold, Program or Display top menu
items causes the security access screen to appear
2. Enter the three-digit security code for the appropriate
security level.
3. If the entry is correct, the appropriate menu screen
appears. If the entry is incorrect, the Invalid Code
screen appears. The Enter Security Code screen
reappears after 2 seconds.
5.7 Using Hold
5.7.1 Purpose
The analyzer output is always proportional to measured
value. To prevent improper operation of systems or
pumps that are controlled directly by the current
output, place the analyzer in hold before removing
the sensor for calibration and maintenance. Be sure
to remove the analyzer from hold once calibration is
complete. During hold, both outputs remain at the last
value. Once in hold, all current outputs remain on
Hold indefinitely.
5.7.2 Using the Hold Function
To hold the outputs,
1. Press MENU. The main menu screen appears.
Choose Hold.
2. The Hold Outputs and Alarms? screen
appears. Choose yes to place the analyzer in
hold. Choose No to take the analyzer out of
hold.
Note: There are no alarm relays with this con
figuration. Current outputs are included with all
configurations.
3. The Hold screen will then appear and Hold
will remain on indefinitely until Hold is
disabled .
