5.7 Internal calibrated leak replacement
Checking the condition of the internal calibrated leak
Change the internal calibrated leak if it has significant impact marks: it must be replaced.
Recalibration of a calibrated leak with tank
To guarantee the reliability of the test, we recommend that you regularly recalibrate (2
years recommended) every calibrated leak with tank to check its leak rate: this applies to
both internal and external calibrated leaks.
Return the calibrated leak for recalibration to the manufacturer’s service center.
Prerequisite
►
Remove the cover (see chapter “Cover disassembly/reassembly”).
Disassembly
Never separate the temperature sensor from the calibrated leak.
Reassembly
1. Follow the disassembly steps in reverse.
2. Update the parameters of the calibrated leak (see chapter “Calibrated leak setting” of the operat-
ing instructions).
–
This operation can be carried out with the information featured on the calibrated leak rating
plate or the calibrated leak certificate supplied with the leak.
