5.3 Reviewing instrument configuration
To review if the analyzer is set up as expected, choose the
Configuration
,
Configuration view
command.
You may change a number of these settings using the WinLog97 program. The modifiable settings,
and information relating to these settings are listed in the next section,
Configuring the instrument
.
However, should you see any unexpected items listed on your screen which you are unable to
correct, please contact your Hach Lange representative.
5.4 Configuring the instrument
The analyzer can be readily configured for your application using the following commands in the
Configuration
menu. The instrument must be connected to your PC in order to change its
configuration.
5.4.1 Automatic data acquisition - setting sampling intervals
The instrument can perform as a standalone data acquisition device, automatically recording gas
measurements with the date and time, and storing up to 500 of these values. Choosing the
WinLog97 program's
Configuration
,
Sampling Rate
menu lets you select time intervals (acquisition
rate) for this storage capability.
Use the slide bar to view and select a sampling rate, from 15 seconds to 1 hour. The selected rate is
shown in the
Acquisition rate
window. Click
OK
to save this rate. Once your choice is made, the
instrument can be used independently of the WinLog97 program for data acquisition.
Note: The Acquisition rate set via this menu is independent from the monitoring chart updating rate described in
Monitoring measurements in real-time
on page 9. The sampling rate menu applies only to automatic data
acquisition, while the chart updating rate is used only for displaying real-time results via the monitoring chart.
5.4.2 Membrane selection
You may find it necessary to use a different type of membrane for different applications. Naturally,
with any membrane change, you will need to re-calibrate (see
on page 13). You
should also consider the changes in required flow rates and response times, which are specified in
the accompanying Sensor Manual.
To re-configure the analyzer, choose
Configuration
,
Membrane
to bring up the box which reveals
the membrane models available. Choose
OK
when the desired membrane is selected.
5.4.3 Selecting type of calibration
5.4.3.1 Select from the PC
You can use the
Configuration
,
Calibration mode
command to select how the sensor is to be
calibrated.
Note: Only the calibration modes applicable to your sensor can be selected. Others will be grayed out.
Choose
In Air
to allow calibration of the sensor in air. Choose
In Line
to calibrate the sensor directly
in the sampling line, in a sample of known gas content. In instrument models that measure gaseous
samples, you may select
In a Span Gas
to calibrate. Choose
OK
when the desired mode is selected.
5.4.3.2 Select from the instrument
1.
Switch the instrument power
OFF
2.
Switch the instrument on by holding down the
CAL

button
while still pressing the
CAL
button
3.
The instrument display will show either
SPA
for span gas calibration,
LI
for in line calibration, or
Air
for in air calibration
4.
Use the
Up/Down Arrow
buttons to change the mode to your choice
5.
Press the
STO
button to set the selected mode. The instrument displays
Sto
for a few seconds,
then returns to measurement mode
