P21
SENSOR TYPE (E)
Defines the type and number of load sensors providing the load signal(s) to the CompuScale III.
enter:
0 = LVDT (linear variable differential transformer)
1 = 1 load cell(MIC)
2 = 2 load cells (F)(MSI)
4 = 4 load cells(MMI-2)
8 = 8 load cells(MMI-3 or 4, LCPA-08 option required)
P22
ECAL ADJUST
Applies and permits the adjustment of the internal electronic test reference.
Refer to Calibration\Alternate Test References for ECAL Span calibration instructions.
ECAL Adjust cannot be accessed unless the ECAL Test Reference (P20) is selected.
ECAL is adjusted in the RUN mode with no material on the belt, or Test Weight applied to the belt scale. When
the adjust option is selected, the simulated belt scale input is applied to the CompuScale III. Record all totalizer
values before and after adjusting ECAL.
To adjust ECAL:
a)
Enter the RUN mode before accessing P22 and selecting the adjust option.
b)
Press "CLEAR" before keying in the estimated reference value, (range = 0 to 4095),
and pressing "ENTER". If a Span calibration already exists, entering 0 automatically adjusts
ECAL to 100% of the current span.
c)
Repeat step b) as required while observing the Rate Bar Graph.
d)
Briefly press "4" (increase by 10’s) or "8" (decrease by 1’s) to fine adjust the
reference value, if necessary.
e)
When the Rate Bar Graph indicates the desired simulated Rate, press "ENTER".
f)
Press "ENTER" again to Factor ECAL to the current span and complete the adjustment.
enter:
0 = ECAL off, (if P20=1, ECAL will automatically be applied when a Span calibration,
or Factoring process is activated, and removed when the process is complete.
1 = ECAL on, (ECAL will be held on except while a Zero calibration is in progress).
2 = ECAL Adjust (adjust as desired, F = 200).
