When your LANDTEC instrument reaches our service facility, its condition is assessed with the following tests and checks:
- General operations
-
The main functions of the gas analyzers operation are checked
to ensure that they are within specification.
- Barometric pressure reading
-
The barometric pressure reading is checked to ensure it is within
specification. This is carried out
by way of comparing the atmospheric reading against a known standard.
If necessary, reprogramming is quoted.
- Static and differential pressure readings
-
The static and differential pressure transducers are checked to ensure
they are within specifications. This is carried out by comparing
instrument readings to a known standard, applying a known pressure and
noting both readings. If necessary, reprogramming will be quoted.
- Pump functionality (flow and vacuum)
-
All flow and vacuum functions of the internal pump are checked to ensure
the operation is within specification.
-
- Water ingress/blockage
-
The internal filters are checked for cleanliness and moisture ingress to ensure they
are not contaminated.
- Flow fail setting
- The flow fail function is checked to ensure proper operation within the specified limits.
- Gas pod and Temperature probe connectivity reading
-
The connectivity of the gas analyzer is checked to ensure correct
operation and reading performance with accessories.
- Computer controlled gas check
-
Inward and outward gas checks are carried out by way of connecting the gas
analyzer to a custom built computer controlled 'gas checking rig' and
proprietary software. At the inward stage, two sets of readings are taken
- one using the customer's calibration settings and a second set using
factory calibration settings. During this process a range of gases are
used that span the reading range of the gas analyzer.
- Structural and aesthetics check
-
The instrument is checked for cracks, scratches and broken or missing pieces.
After the assessment is made, a quote is issued for all items needing repair/replacement, including
all warranty items and standard servicing and calibration.
The quote is then sent to the customer for item-by-item approval.
