PRO-series Model E3 Electrodeless Conductivity Transmitter

3.5 SET PASSCODE
(feature enabled
or disabled)
The transmitter has a passcode feature to restrict access to
configuration settings and calibration to only authorized
personnel.
•
DISABLED:
With the passcode feature disabled, all con-
figuration settings can be displayed and changed, and the
transmitter can be calibrated.
•
ENABLED:
With the passcode feature enabled, all con-
figuration settings can be displayed -- but they cannot be
changed -- and the CALIBRATE and TEST/MAINT menus
cannot be accessed without the passcode. When you at-
tempt to change a setting in the CONFIGURE menu by
pressing the
ENTER key
, a displayed notification re-
quests passcode entry. A valid passcode entry saves the
changed setting and returns the display to the “MAIN
MENU” branch selection screen. An incorrect passcode
entry causes the display to momentarily show an error
notification before returning to the “MAIN MENU” branch
selection screen. There is no limit on attempts to enter a
valid passcode.
The passcode is factory set to “
3 4 5 6
.” It cannot be changed.
