At this point, the proposed change to the
Scale Factor
will be shown. If you wish to

E-Cal Factor Procedure
This procedure will update the
ECAL Liveload
parameter, using current
Scale Factor
. In
other words, it is the reverse of the
E-Cal Procedure
. It should only be run after a
material or weight procedure has been completed, followed by emptying the hopper and
performing a
Zero Procedure
. The purpose is to correct the calculated
ECAL mV/V
parameter so that it is based on better calibration procedures. If you later run an E-Cal
Procedure, you will get more accurate results.
To run an E-Cal Factor procedure, select this option from the Calibration menu. From this
point on, the test runs just like the E-Cal Procedure. The
ECAL mV/V
parameter will be
adjusted. No change is made to the Scale Factor. The calibration of the feeder is not
affected.
Analog Input Procedure
This procedure allows you to calibrate the two high-resolution analog inputs 1 and 2. You
must be able to set the signals at the source to do this.
Press the number of the analog input to calibrate.
Set the signal at the source to represent zero value, typically 4 mA. The live counts will
vary accordingly. Since the nominal full scale of the high resolution analog input A/D
converter in 1,000,000 counts, the value you see should typically be around 200,000
counts. Push the
Snap Zero
button.
The live value will snap to the New column, Lo row.
