Model NGA2000 PMD 

Introduce a suitable on-scale gas (NOT actual 
sample) into sample inlet. 

Apply power to the PMD Analyzer Module.  If 
it is associated with a Platform, do this by 
plugging in the Platform to a power source.  
The Platform has no ON/OFF power switch.  
Once power is supplied to the Platform, the 
PMD Analyzer Module will be energized. 

If the user's system contains only one Ana-
lyzer Module, all system components, the 
Controller Board and the network "self-install" 
(bind together) during initial startup.  If the 
system contains more than one Analyzer 
Module, the startup sequence will interrogate 
the network to locate and identify all compo-
nents on the network.  The user will have to 
bind appropriate combinations of components 
after the startup sequence. 

After the warm-up period, approximately one 
hour for PMD Module, all modules are com-
pletely functional. 

Enter appropriate data in the Calibration Gas 
List (by making the following display selec-
tions:  Main Menu, Expert Controls and Setup 
[enter security code, if necessary], Analyzer 
Module setup, Calibration Gas List).  Also, en-
ter appropriate values in the Calibration Pa-
rameters menu (by making the following 
display selections:  Main Menu, Expert Con-
trols and Setup [enter security code, if neces-
sary], Analyzer Module Setup, Calibration 
Parameters), particularly data related to which 
ranges are to be zeroed together and how the 
Analyzer Module is expected to calibrate 
ranges (separately or otherwise). 

The Analyzer Module will not allow the user to 
increase the upper limit of a range beyond the 
"maximum range" software setting.  To 
change the "maximum range" value, select 
the following from the Main Menu:  Technical 
Configuration Menu, Service Menu, Manufac-
turing Data, Analyzer Module Data.  Select 
Maximum Range, and use the arrow keys to 
scroll the indicated value.  The same applies 
for "minimum range" settings. 

To achieve full coordination between Analyzer 
Modules and associated I/O Modules, the 
user must bind those components together in 
the System Setup portion of the Technical 
Configuration Menu in software.   

Calibration consists of establishing zero and 
span calibration points.  Generally, zero and 
span calibration should be performed on the 
range that will be used during sample analy-
sis. 

To calibrate the PMD Analyzer Module, intro-
duce zero gas into the SAMPLE INLET, and 
do the following: 

1. If 

the 

Multi-Analyzer Module, split Run 

Mode display is shown, press the DIS-
PLAY softkey until the desired Analyzer's 
Run Mode display is acquired. 

2. Press 

the 

MENUS softkey to enter the 

Main Menu. 

3. Press 

the 

ENTER key to enter the Basic 

Controls menu. 

4. Press 

the 

ZERO softkey to enter the Ana-

lyzer Zero menu. 

5. Press 

the 

ZERO softkey and wait. 

6.  Introduce span gas (Table 3-2 on page 3-

6) into the SAMPLE INLET. 

7. Press 

the 

SPAN softkey to enter the Ana-

lyzer Span menu, press SPAN again and 
wait. 

8. Press 

the 

HOME softkey to re-enter the 

Main Menu.

9. Press 

the 

DISPLAY softkey for the Run 

Mode display.

For users of analyzers with suppressed indi-
cating ranges, it may be desireable to cali-
brate the analyzer zero and span points within 
the suppressed range with gases in the sup-
