monitor and no one has touched the keypad. This will also happen anytime there is a power outage
and power has been returned to the monitor.

A.1.3 Reinitialization
It is suggested that you reinitialize the monitor before programming in your own numbers. This will
wipe out any random settings which may be in the monitor. To reinitialize, follow these instructions.
1. After you have practiced moving up and down in the Main Menu, press 6 or highlight SYSTEM
SETUP and press ENT.
2. Press 2 or highlight INITIALIZATION and press ENT.
3. Press 2 or highlight WHOLE MONITOR and press ENT. A warning will appear on the screen
advising you that “this option requires recalibration and reprogramming!” Press 1 to proceed,
2 to cancel.
A.1.4 Set up Conductivity Preamp Settings and Temperature Compensation
Prior to testing your monitor, set up the internal conductivity preamp for the sensor you are using. If
you purchased a sensor with your monitor, the preamp is set up by the factory and you can proceed
directly to testing. If you change the sensor used and do not verify the preamp setup for your
attached sensor, the conductivity readings may be erroneous. Set up the preamp by using the
following steps.
