electrical shock.)
10) Determine the machine rating number that must be programmed
into the "portable" System 1100 connected to the load cells as
follows:
If a two channel System 1100 is used as the "portable"
calibration unit, the machine rating number is twice (2X) the
tonnage capacity of the load cell(s) used; i.e., if either one
or two 100 ton load cells are used to load the machine, the
correct machine rating number is 2 X 100 tons = 200.0 tons.
If a four channel System 1100 is used as the "portable"
calibration unit, the machine rating number is our times (4X)
the tonnage capacity of the load cell(s) used; i.e., if one,
two, three, or four 100 ton load cells are used to load the
machine, the correct machine rating number is 4 X 100 tons =
400.0 tons.
11) Set the machine rating number into the "portable" System 1100
unit by using the MACH RATING option in the Config menu
(section 2.8.2).
Note that, when a System 1100 is used as a calibration unit in
conjunction with load cells, the machine rating number is a
scale factor dependent on the rated tonnage capacity of the
load cell(s) used in calibration and is not determined by the
tonnage capacity of the machine being calibrated.
If error codes relating to setpoint limits occur, follow step
12 of this procedure then press the CLEAR key clear the
errors.
12) Follow the procedures in the section 2.4.1 of this manual to
set the high setpoint for each channel of the "portable"
System 1100 unit used for calibration to about 10% greater
than the rated tonnage of the load cell(s) used in
calibration. For example, if one or more 100 ton load cells
are used to calibrate a machine, each channel high setpoint
limit should be set to 110.0 tons (10% more than 100 tons)
regardless of whether a two channel, or four channel System
