7.19.3 Calibration|Adjustment Calibration serves to compare the internal pressure sensor and the external
(F3-Service) 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
®
4 plus Filter tester and can be printed
out at any time.
For the internal pressure sensor and the external pressure sensor, you set a
calibration interval and a calibration reminder.
Before performing the actual calibration, allow Sartocheck
®
4 plus Filter tester to
warm up to operating temperature. This is done by turning Sartocheck
®
4 plus Filter
tester 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.
Firstly, you define which sensor and|or sensor inlet you want to calibrate.
In the case of multi-unit operation, all logged-on multi-units are displayed.
Their sensors are also calibrated via the central unit and adjusted, if applicable.
By contrast, all calibration curves are stored in each multi-unit.
Use the function keys F1-F5 to select the test unit (MultiUnit). The internal
pressure sensor calibration values of the respective test unit may be printed.
Use the “Print” button to print out the calibration protocol of the sensors
highlighted in blue.
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
®
4 plus Bag tester 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 whether
a calibration or adjustment is to be performed. You can also enter information about
the reference equipment (F4-F10 for internal pressure sensor, F4-F8 for external
pressure sensor).
