1. The command for number of linearization points is 29 (Table 5.4) and the data has
offset -2. Send command: *W2905 means 7 point of linearization are active.
2. Out of ten points the very first one is not available through the communication
commands. The nine points from 1st to 9th must represent min and max of each interval
respectively, and the points in between them must progressively incrementing. The
commands for these points are 2B to 33 (Table 5.4)
2.1 Send command: *W2B2001F4 means 5 mV input for Scale 1/Offset 1 is active, DP=2
2.2 Send command: *W2C2003E8 means 10 mV input for Scale 2/Offset 2 is active, DP=2
2.3 Send command: *W2D2005DC means 15 mV input for Scale 3/Offset 3 is active, DP=2
2.4 Send command: *W2E2007D0 means 20 mV input for Scale 4/Offset 4 is active, DP=2
2.5 Send command: *W2F2009C4 means 25 mV input for Scale 5/Offset 5 is active, DP=2
2.6 Send command: *W30200BB8 means 30 mV input for Scale 6/Offset 6 is active, DP=2
3. Calculate Scale.
Rd(n) - Rd(n-
Scale = -------------------- , where n is an interger
IN(n) - IN(n-
The commands for these points are 34 to 3C (Table 5.4)
3.1 Scale 1 = (28 - 0) / (500 - 0) = 56000 x E-6
56000 Dec = DAC0 Hex is a Reading Scale Data (RDGSC1.18~0 = DAC0)
E-6 represented as RDGSC1.23~20 = 7 (DP+1=7)
RDGSC1.19 = 0 (direct scale)
Send command: *W3470DAC0
3.2 Scale 2 = (110 - 28) / (1000 - 500) = 164000 x E-6
RDGSC2.18~0 = 164000 Dec = 280A0 Hex
RDGSC2.23~20 = 7
RDGSC2.19~0 = 0
Send command: *W357280A0
3.3 Scale 3 = (250 - 110) / (1500 - 1000) = 280000 x E-6
RDGSC3.18~0 = 280000 Dec = 445C0 Hex
RDGSC3.23~20 = 7
RDGSC3.19~0 = 0
Send command: *W367445C0
