Startup and Operation of the Leak Detector

To start the leak detector:

Plug the leak detector power cord into an appropriate mains supply receptacle.

Move the power switch on the rear power control panel to the l position. If you

have a bench system with a separate backing/roughing pump, turn the pump

on. The Test button is disabled on start up until System Ready appears on the

Home screen. Once the leak detector boots up a startup wizard appears on the

touch panel display allowing you to change the time and language, and the

ability to scan a QR code for product registration.

Select choice of language, time/type (AM, PM & 24) and system setup.

The System Ready indication appears on the Home screen. If the leak detector

is being started after a long period of being off (several hours), it can take up to

five and a half minutes to stabilize and provide reliable, quantitative leak rate

readings.

The leak detector is capable of performing an automated calibration routine

using either an internal calibrated leak (factory installed), or an external

calibrated leak placed into the system test port. Refer Section "Calibration Set-

Up" to properly set-up the leak detector for auto-calibration.

If the system was recently calibrated before shut down, it can be used for

NOTE

qualitative testing. Read the standard leak to verify accuracy. For more accurate

quantitative leak values, perform a calibration 20 minutes after start-up.

To accurately read in the most sensitive decades (E-10 and E-11), warm up the leak

detector for at least one hour prior to performing a full calibration. When leak

checking in the E-9 atm-cc/sec range or higher, you can use the leak detector prior

to one hour and verify system performance by assuring that the system can

accurately read the internal calibrated leak.

The system is shipped from Agilent with the Minimum Range function turned ON

and the bottom range set at the E-10 range (atm-cc/sec). To accurately test in the

E-11 range, careful control of materials and the environment is required, consult a

Agilent sales engineer for support.
