Buf1 done: 4.01 @25°C

3.A screen like the one on the left will appear after stabilization.

Use the arrow keys to select the correct buffer.

If the correct buffer does not appear, refer to Section 5.9 and select a buffer group that includes the desired buffers. As usual, to cancel the calibration, press Abort (F1).

Abort Cont

When the correct buffer is shown, remove the sensor from buffer 1, rinse and gently dry it. Press Cont (F3) to continue.

NOTE

The calibration calculation does not occur until buffer 2 is com- pleted. Aborting the calibration at this point will not change the reading of the controller.

4.This screen appears immediately after pressing the Cont key in step 3.

Place the sensor into the second buffer. Press Cont (F3) to proceed. The word "Wait" flashes (as before) until the sensor is stabilized.

Press Abort (F1) to cancel the calibration if the process is taking too long. (see step 2).

5.A screen like the one on the left will appear after stabilization. Use the arrow keys to select the correct buffer, and press Cont (F3). If the correct buffer does not appear, refer to Section 5.9 and select a buffer group that includes the desired buffers. As usual, to cancel the calibration, press Abort (F1).

This completes the calibration. The controller has now recalculated the slope and the zero offset of the sensor.

CALIBRATION NOTES

1.A two-point calibration should always be followed by a sin- gle-point calibration (see Section 4.4).

2.After a buffer calibration, the electrode slope value can be checked to see if the electrode is aging.

3.If the sensor is not at the same temperature as the buffer the cal- ibration will be in error.

NOTE

If hold mode was turned ON, be certain to install the sensor back in the process and change the setting to OFF to resume normal operation before leaving the controller. The hold mode screen will appear again before the main display is shown. Follow the same routine as in the Note for step 1 to turn the Hold Mode Off and then press Exit (F1).
