13-2 Calibration Examples
A 100 pound load will be used to calibrate the system.
The full-scale mV/V value of the load cell, as obtained
from its calibration record, is 2.997 mV/V at 10 volts exci-
tation. The address of the PIM-3 has been previously set
to "01" with the
W4
command.
First, the proper setup values for the transducer must
be entered into the PIM-3. Enter the following commands
into the PIM-3, ending with a carriage return (ASCII code
13 decimal, shown here as <ret>):
#01W5150
<ret>
#01W6pounds
<ret>
#01W72.997
<ret>
#01WK100
<ret>
#01W91
<ret>
Second, the analog to digital converter inside the PIM-
3 is internally calibrated to minimize temperature errors.
This may be done regardless of the load on the trans-
ducer.
#01F3
<ret>
Next, the tare value will be entered into the PIM-3. All
load must be removed from the transducer before this
command is performed so that the PIM-3 will recognize
this point as "zero".
#01F1
<ret>
Finally, place a 100 pound load on the transducer, and
calibrate the system.
#01F8
<ret>
This completes the system calibration to a known load.
