This  is  an  important  parameter  to  understand.  At  sea-level  and  moderate  temperatures  the  difference  between  these 
settings  will  be  minimal,  but  at  high  elevations  or  varied  temperatures  the  flow  rate  can  be  greatly  affected  by  this 
setting. NOTE: Section 5.2 contains a detailed description of each of these flow types, and should be studied to ensure 
proper operation of the unit. 
 
Cv: 

This  value  is  the  factory-set  Coefficient  of  Variability  for  the  internal  flow  sensor.  The  value  of  Cv  is  only 

changed  by  the  user  when  performing  a  flow  calibration  on  manual  valve  (metered)  or  STD  flow  units.  ACTUAL  flow 
controlled units almost never need to have this value altered. 
 
Qo: 

This value is the factory-set zero correction factor for the internal flow sensor. The value of Qo is only changed 

by the user  when performing a flow calibration on manual valve (metered) or STD flow units. ACTUAL flow controlled 
units almost never need to have this value altered. 
 
ABS:  The ABS value is the factory-set mass of the reference membrane foil used during the automatic span check. 
This  value  is  compared  to  the  measured  value  each  hour  (see  section  4.2).  Each  unit’s  ABS  value  is  different,  but  is 
typically  around  0.800  mg.  The  ABS  value  is  never  changed  by  the  operator  unless  the  span  membrane  is 
replaced due to damage. 
 
µsw: 

This is called the Mu-switch value, and is the factory-set mass absorption coefficient used by the APDA-371 in 

the concentration calculations. Typical values are about 0.285 to 0.310. Warning: This is a unit-specific calibration 
value  which  may  significantly  affect  the  accuracy  of  the  unit.  Never  change  this  value  without  specific 
instruction from HORIBA. 
 
K: 

The K-factor is the factory-set slope correction (multiplier) for the APDA-371 concentration. The K-factor value 

is determined by dynamic testing of the APDA-371 in the factory smoke chamber. This will always be a value between 
0.9 to  1.1. All  of the stored and displayed  data contains this correction. Warning: This is a unit-specific  calibration 
value  which  may  significantly  affect  the  accuracy  of  the  unit.  Never  change  this  value  without  specific 
instruction from HORIBA. 
 
BKGD: The BACKGROUND value is the factory-set zero correction (slope offset) for the APDA-371 concentration. This 
is determined by running the unit for at least 72 hours with a 0.2 micron zero filter on the inlet. The concentration values 
over this time are averaged, and the BKGD is the negative of this average. All of the stored and displayed data contains 
this correction. The BKGD value is typically between 0.000 and -0.005 mg/m

3

. HORIBA does offer a zero filter kit (BX-

302)  which  may  be  used  to  audit  this  value,  and  comes  with  complete  instructions.  Warning:  This  is  a  unit-specific 
calibration  value  which  may  significantly  affect  the  accuracy  of  the  unit.  Note:  The  BKGD  value  is  not  to  be 
confused with the OFFSET (range offset) value in the SETUP > SAMPLE menu. See section 6.2.  
 
STD TEMP: 

This  is  the  value  of  standard  temperature,  used  for  standard  flow  or  concentration  calculations.  In  the 

U.S. the value of standard temperature is usually 25 degrees C as mandated by the USEPA. Some other countries use 
a standard temperature value of 0C or 20C. This setting is not available on units using firmware prior to rev 3.0. 
 
HEATER: 

This setting selects which mode the Smart Inlet Heater is used in. When set to AUTO, the Smart Heater 

will  use  the  filter  RH  and  temperature  sensors  to  control  the  inlet  tube  heating.  When  set  to  MANUAL,  the  unit  will 
simply turn the heater on all the time regardless of filter conditions. The actual setup parameters for the Smart Heater 
are located in the SETUP > HEATER menu, which will not appear unless this value is set to AUTO. The operator may 
safely set this parameter as required. HORIBA recommends using the AUTO setting. This value must be set to AUTO 
for PM

 monitoring. 

 

6.4 

EXTRA1 Screen 

The settings in the EXTRA1 screen are special settings that have been installed for special applications and generally 
will never be changed. 
 

 

e1 

Low Concentration Limit. The lowest concentration value the APDA-371 is allowed to store or display, despite 
what  it  measured.  Any  measurements  below  this  value  will  be  clamped.  The  range  is  -0.015mg  to  +0.010mg, 
and the default  value  is -0.015mg. Note: This value  is not  to  be confused  with the OFFSET value  which sets 
the lower limit of the measurement range, or the BKGD value which is the zero correction.
