Factory Default Passcode
The factory default passcode for both minor and major passcodes is 0800.
Checking Factory Configuration
Following the structure diagrams in Appendix A and using the arrow keys, you can step through
the product structure as configured in the factory. The factory default values are listed in
Appendix B. There is space provided to make notations in the last column of the table that
comprises this appendix.
Verifying Valid Measurements
Your transmitter was calibrated at the factory. Therefore, you should not have to calibrate it.
However, if you wish to check your calibration, place your sensor in a solution of known value
and, using the Down arrow key, check that the temperature on the second line of the display
agrees with the actual temperature of the solution. Then check the value on the top line of your
display. If the value does not agree with the known value of the solution, recalibrate your
transmitter. The simplest method of doing this is to perform a single point manual calibration
using the solution approach. See “Manual Calibration” on page 31.
Basic Operation in Measure Mode
Measure is the normal operating mode of your transmitter. The pH, ORP, or ISE measurement is
shown on the top line of the display. The second line of your display shows the absolute value of
the sensor signal in millivolts, the output in 4 to 20 mA, or the temperature, depending on your
