Explanation of the measuring technology terms used
Single
measurement:
This refers to the analysis of the contamination of a specified
sample quantity (
measurement volume
). The result of a
single measurement is the
measured value
.
Measuring point
The name of the location at which the FCU is connected to
the hydraulic system.
This designation (max. 20 characters) can be entered in the
FCU for documentation purposes.
Example: pump press W3
Measurement
volume
:
Sample quantity which is analyzed for determining a
measured value
.(The measurement volume can be set by
the user)
Measured value
The contamination codes determined by a single
measurement, shown as a three-digit ISO code or NAS
codes or SAE codes of the individual particle size channels.
Measurement:
After the "OK/START" - key is pressed, a
single
measurement
begins, followed immediately upon completion
by the next
single measurement
until the "STOP" - key is
pressed (mode M1, M2, M4) or the target cleanliness (mode
M3) is reached.
This series of
single measurements
is referred to as a
measurement
for convenience reasons.
Log:
A measurement is described by a
log
. It is comprised of the
log header
and the
log lines
. The FCU saves up to 100 logs.
Log header
:
The log header contains:
A log number (a consecutive log number is automatically
generated every time a measurement sequence is initiated).
The designation of the
measurement point
(can be entered
by the user), date + time of the beginning and end of the
measurement sequence
(generated automatically)
Averaging interval
Number of
log lines
Measurement volume
Example:
Memory log:.........................6
Measuring point: ..................25
from: ....................................15.09.2003, 8:32
to:.........................................15.09.2003, 10:42
Averaging interval:...............10 min
Number of log lines:.............13
Measurement volume: .........100 ml
Log line:
A
log line
consists of the time and results (4 particle
channels and flow rate with NAS) (3 particle channels and
flow rate with ISO and SAE) of a measurement.
The FCU can store up to 3000 log lines
.
