Galvanic Applied Sciences ProTech903W - Field Names and Explanations

Revision 1 68 9/10/2019
5.4.1 Field Names and Explanations
The left side of the Analysis tab includes 20 fields which provide general information about
the status of the analyzer (Table 5-5). The first four fields can be edited as described in
Section 5.9 but the rest cannot be edited.
Table 5-5: Analysis Window Fields
Field Name
Explanation
Analyzer Date and
Time
Shows the current date and time on the analyzer. It is important that
this be set correctly so that the archived data has the correct time
stamp. If this is not correct, ensure that the computer’s time and
date is correct, and then press the Synchronize Time button.
Site ID
The analyzer serial number
Site
Shows the site name that the analyzer is installed at
Location
Shows the specific location that the analyzer is installed at.
Analysis State
Shows the current state of the analyzer. The various analysis states
are shown in Table 4-2.
Current Analysis
Shows the current run type being performed by the analyzer The
run type name that is displayed is entered under Streams Name
field on the Streams tab.
Analysis Time
Shows the number of seconds elapsed since the beginning of the
current analysis cycle.
Run Number
Shows the current number of runs of the current analysis type, as
well as the total number of runs of this type to be performed.
Trended Reading
Shows a trended concentration reading that takes the values of
several past concentration readings of the same run type into
account.
PAA
Shows the live Predictive Alarm Analysis (PAA), (dv/dt*gain)
Raw mV
Shows the current raw photodiode detector output, in millivolts. This
reading starts at around 1000mV at the start of an analysis, and
drops as the analysis proceeds. This value can be displayed as
live mV (LmV) on the display (see Section 4.3.1).
dV/dT
Shows the rate of change in sensor output.
mV
Shows the absolute value of the sensor output, increasing from
zero at the beginning of an analysis. This value can be displayed
as corrected mV (mV) on the display (see Section 4.3.1).
Zero Offset
Shows the value subtracted from all concentration readings. This
value is the parameter that must be subtracted from a reading
taken on gas containing no phosgene in order to make the analyzer
read approximately 0.00ppm.
Calibration Gain
Shows the value that the dv/dt (rate of stain formation on the tape)
is multiplied by in order to produce a real concentration reading.
Sensor LED Current
Shows the current used to ensure a reading of 1000mV is obtained
by the sensor block on pure white tape.
Sensor Temperature
Shows the current ambient temperature at the sensor block (in
o
C).
Tape Remaining
Shows the length of tape, in feet, remaining in the reel. See Section
5.6.1 for more information on how this is calculated.
Run Counter
Shows the current number of runs of all types carried out by the
analyzer since it was first started up.
Sequencer State
Shows if the sequencer is currently in an automatic or manual state.
