4.2.22 PSM VALUE Parameter 'smpl', live
Value = -1E33 ... -1E-37 , 0 , 1E-37 ... 1E33
Setting sample size.
In mode DOS only, in other modes, the command is not accepted and bit 0 of information
byte 2 is set to 1.
4.2.23 UNI X Unit, live
X = 0 ... 9, J, K
Selecting the unit:
X = 0, %
X = 1, g
X = 2, mg
X = 3, g/l
X = 4, mg/l
X = 5, mol
X = 6, mol/l
X = 7, ml
X = 8, l
X = 9, /pc (per piece)
X = J, no unit
X = K, ppm
In mode DOS only, in other modes, the command is not accepted and bit 0 of information
byte 2 is set to 1.
4.2.24 VUP VALUE Rate up, live
Value = 0.001 ... 150.0
Setting rate up in ml/min.
If rate up is set to 'analogue', it is changed automatically to rate up digital.
Input range depends on the cylinder volume of the exchange unit:
Cylinder
ml
rate
min
ml/min
rate
max
ml/min
1 0.001 3
5 0.005 15
10 0.010 30
20 0.020 60
50 0.050 150
If a value is entered which is too high or too low, resp., the Dosimat corrects the value
automatically to rate
max
or rate
min.
resp. and sets bit 1 of information byte 2 to 1 (see
4.2.7). To set rate
max ,
it is therefore possible to always enter 150 ml/min.
4.2.25 VDW VALUE Rate down, live
Value = 0.001 ... 150.0
Setting rate down in ml/min.
If rate down is set to 'analogue', it is changed automatically to rate down digital.
Input range depends on the cylinder volume of the exchange unit:
