Parameter  Description 
Reac. Time  The unit is the interval of collecting photometric data, which 
equals to 18 seconds for BS-120/BS-130 and 16.3 seconds 
for BS-180/BS-190. 
The first edit box  is start time, and the  second one is  end 
time. 
For  the  Endpoint  method,  the  reaction  time  refers  to  the 
interval between the start of the reaction and the end of the 
reaction. 
For the Kinetic or Fixed-time method, the reaction time refers 
to the interval between the point when the reaction becomes 
stabilized  and  the  point  when  the  reaction  is  no  longer 
monitored. 
If  the  reaction  time  is  negative,  it  means  that  you  should 
deduct the reagent blank or sample blank. 
For  the  single-reagent  test,  the  analyzer  defines  the 
photometric  data  collection  point  as  0  exactly  before  the 
sample has been dispensed, that is, “0” means the reagent 
blank point. The value must not be negative   
For  the  double-reagent  test,  the  analyzer  defines  the 
photometric  data  collection  point  as  0  exactly  after  the 
second  reagent  has  been  dispensed.  The  value  can  be 
negative. 
Incuba. Time  The system assigns the incubation time as 5 minutes. 
Unit  Unit of the result. 
Precision  Precision of the result. 
R1  It refers to the volume of the first reagent to be dispensed for 
the reaction. Increment is 1.   
BS-120/BS-130: 180-450µl 
BS-180/BS-190: 150-450µl
 
R2  It refers to the volume of the second reagent to be dispensed 
for the reaction. Increment is 1.   
BS-120/BS-130: 30-450µ 
BS-180/BS-190: 5-450µl 
Sample 
Volume 
It refers to the sample volume (3-45µl) to be dispensed for 
the reaction. Increment is 0.5. 
NOTE 
 
The  sum  of  the  entered  R1,  Sample  Volume 
and R2 (as needed) must be as follows: 
213µl-500µl for BS-120/BS-130 
158µl-500µl for BS-180/BS-190
