The on screen commands guide you through the linear offset
routine. The Calibration screen prompts you to start.
2. Press the Enter button to start the linear offset process. To re-
turn to the Configuration Screen, press the Cancel button. Af-
ter pressing the Enter button, the Calibration screen prompts
you to insert a fresh standard and seal the chamber.
3. Empty the whole vial of solution into a sample cup. We rec-
ommend using the 6.00 NaCl (0.76 a
w

offset using steam distilled water. Ensure the rim and outside
of the cup are clean. Place the sample cup in the TDL sample
chamber.
Note: You may use the same verification standard to verify
and adjust the linear offset.
