ASAP 2020 Confirm

Routine Maintenance

The procedures in this section are performed as needed.

Cleaning the Analyzer

The ASAP 2020 should be cleaned every six months, or sooner if required.
Clean the outside casing of the analyzer (except for the shields) with a clean cloth dampened
with isopropyl alcohol (IPA), a mild detergent in water, or a 3% hydrogen peroxide solution.
It is not necessary to remove any switches or screws to clean the outside casing. Use only a
mild detergent in water to clean the shields.
Use only a mild detergent in water to clean the shields. Do not use isopropyl
alcohol. Isopropyl alcohol could damage the surface of the shield.

Calibrating the Pressure Offset

When operating the system in manual mode, Calibration > Pressure Zero enables you to
evacuate the manifold and zero all the transducers. Your system may contain up to three
transducers.
The system automatically zeros the transducers before an analysis begins. Therefore, you do
not need to use this feature unless you are operating the system in manual mode.
Perform the following steps to calibrate the pressure gauge:
1. Select Unit > Calibration > Pressure Zero; the Calibrate Pressure Offset dialog is
displayed
.
2. Click
Start
8-20
to evacuate the manifold and zero the pressure gauge(s).
