7.16.3 Calibration|Alignment (F4-Service)
The calibration serves to compare the internal pressure sensor with an appropriate
reference. If the deviations are outside the defined tolerance range an adjustment
is required. During adjustment to the defined pressure and|or current, surge sites
are set and compared with the reference. The reference values are entered into the
adjustment chart. After the adjustment is completed you can immediately start a
new calibration.
The calibration curves are stored in Sartocheck
®
3 plus and can be printed out at
any time.
For the internal pressure sensor you set a calibration interval and a calibration
reminder.
Before performing the actual calibration, allow Sartocheck
®
3 plus to warm up to
operating temperature. This is done by turning Sartocheck
®
3 plus on 30 minutes
prior to calibration.
The procedures for calibration and adjustment are identical.
The calculation procedures differ in that calibration calculates and displays the
deviation to internal adjustment curves. During adjustment, on the other hand,
a new adjustment curve is plotted.
With “Print”, you can print out the calibration log of the sensor.
Press “Page Down” to go to the next window, in which the calibration interval
and the calibration reminder for the sensor selected can be predefined.
The calibration should be checked at least once or twice annually. For your
assistance, Sartocheck
®
3 plus provides the option to enter the calibration interval
and a calibration reminder. These entries only serve as a reminder and do not affect
the functioning of the device.
The calibration interval can be preset from 1 day to a maximum of 366 days.
The same applies to the calibration reminder, which can be predefined from
0 to 366 days. The value “0” disables the reminder function.
After you have set the calibration interval and the reminder interval before the
calibration, press Page Down to go to the next screen page. Use F1 to define wheth-
er a calibration or adjustment is to be performed. You can also enter
information about the reference equipment (F4-F10 for internal pressure sensor.
