Step 5 - The calibration is now finished. The readings in the
four bottom lines are the actual pressure on all four pressure
transducers. The values must be 200.0 +/-1.0mmHg.
Carefully remove the calibration shunt tube and reconnect
the tubing to the glass cannulas.
3.7.3 PH CALIBRATION PROCEDURE (OPTIONAL)
Before the pH calibration is performed be sure to select the
way the pH electrode is to be used. See the sub-menu pH Set-
up under Interface Settings (3.6.5.2 pH Set-up Menu).
The temperature is an important parameter in the calibration
formula and is obtained automatically if AUTO is selected in
Temperature compensation function.
If Manual is selected, the manual temperature is used in the
pH calibration formula, and the temperature probe is de-
activated.
In the Manual mode, the temperature of the calibration
buffers is measured with a thermometer and entered
manually in the Manual Temp. value line.
The pH calibration procedure is listed in 4 individual steps
and needs to be performed one at a time.
Step 1 - Step 1 involves cleaning the pH electrode and the
temperature probe with double distilled water. When ready
