EXTERNAL DATALOGGER INTERFACE SYSTEM 

This section describes the configuration of the APDA-371 to work with a separate, external datalogger. The APDA-371 
provides  an  analog  concentration  output  voltage,  as  well  as  an  array  of  relay  inputs  and  outputs.  These  allow  the 
APDA-371  to  function  as  a  sensor  in  a  larger  array  of  data  collection  instruments.  There  are  a  variety  of  dataloggers 
available  which  are compatible  with  the  APDA-371  outputs, so consult the manual for  your datalogger for the specific 
setup requirements.  
 

8.1 

Analog Concentration Output Signal 

The  primary  link  between  the  APDA-371  and  an  external  datalogger  is  the  analog  concentration  output  signal.  The 
analog output type is selectable between isolated voltage (0-1 or 0-10 volt DC) and isolated current (4-20 or 0-16 mA). 
The rear panel dipswitches are used to select the output as shown in the table below. The one-volt range is by far the 
most common. The full-scale value of the output voltage corresponds to the full-scale measurement of the APDA-371, 
determined by the RANGE and OFFSET setting. See Section 6.2. In the majority  of applications, the analog output is 
set for 0-1 volt = 0 to 1.000mg or 0-1 volt = -.005 to .995mg. If the OFFSET is set to -0.015 for PM

2.5

, then the analog 

output is 0-1 volt = -.015 to .985mg. The analog output should be tested as described in Section 7.12.

In  most  cases  the  analog  output  is  the  only  channel  available  between  the  APDA-371  and  the  datalogger,  and  any 
errors  generated  by  the  APDA  must  be  reported  using  the  same  voltage  signal.  The  APDA-371  will  set  the  analog 
output to  its full-scale reading  when any of the selected errors occur. The errors which cause this are selectable, and 
are  described  in  section  6.5.  The  external  datalogger  should  be  programmed  to  recognize  a  full-scale  reading  as  an 
error, not a valid concentration. This method is used because it is very rare for a concentration reading to exceed the 
range of the APDA-371. The digital data values stored in the APDA are unaffected and may be viewed with the display 
or by downloading.
