7.6.1

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 cor-
rect access code for All security level, the user has access to all menu functions, including
Programming, Calibration, Hold and Display.
7.6.2

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.

Purpose

The transmitter 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 transmitter
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.
