b. If separate security codes have been assigned to calibrate and config-

ure, entering the calibrate code will allow the user access to only the cal-

ibrate and hold menus; entering the configuration code will allow the user

5.6 SECURITY

5.6.1 How the Security Code Works

Use security codes to prevent accidental or unwanted changes to program settings, displays, and calibration. Two

three-digit security codes can be used to do the following…

a. Allow a user to view the default display and information screens only.

b. Allow a user access to the calibration and hold menus only.

c. Allow a user access to all the menus.

5.6.2 Bypassing the Security Code

Enter 555. The main menu will open.

5.6.3 Setting a Security Code

See Section 7.6.

5.7 USING HOLD (HART version only)

5.7.1 Purpose

The transmitter output is always proportional to the process variable (conductivity or resistivity). To prevent improper

operation of control systems or dosing pumps, place the transmitter in hold before removing the sensor for mainte-

nance. Be sure to remove the transmitter from hold once the work is complete and the sensor has been returned to

the process liquid. During hold the transmitter current goes to the value programmed by the user. Once in hold, the

transmitter remains there indefinitely. While in hold, the word "hold" appears periodically in the display.

5.7.2 Using the Hold Function

1. Press MENU. The main menu screen appears. Choose Hold.

2. The Hold Output screen appears. Choose Yes to put the transmitter in hold.

3. The top line in the display is the present current output. Use the arrow keys

to change the number in the second line to the desired current during hold.

4. The main display screen appears.

5. To take the transmitter out of hole, repeat steps 1 and 2 and choose No in

step 2.
