8. Operating Mode (oP)
Option
Description
Std
Standard (not Legal for Trade), full range zero.
44
HB44 (Legal for Trade) +/- 1.9% gross zero range.
CAn
Canadian Weights and Measures Approval (Legal for Trade) +/- 4.0 % gross zero range.
The Operating Mode defines whether or not the 4200 will operate in a "Legal for Trade" or
a "Not Legal for Trade" mode.
In the Legal-for-Trade "44" mode, the 4200's ZERO button and "Auto Zero Tracking"
parameter will only zero out up to 1.9% of the scale's capacity in compliance with NIST
Handbook 44. The reference point for this 1.9% band is based on the calibration zero
point of the scale. If the load on the platform is beyond the 1.9% of capacity, a zero error
will result. If this happens, the load must be removed and the indicator restarted.
Therefore, care should be taken to make sure that the scale platform is empty when the
scale is turned on to insure proper operation of the ZERO button.
In the Legal-for-Trade "CAn" mode, the 4200's ZERO button and "Auto Zero Tracking"
parameter will only zero out up to 4.0% of the scale's capacity in compliance with Canadian
Weights and Measures. The reference point for this 4.0% band is based on the calibration
zero point of the scale. If the load on the platform is beyond the 4.0% of capacity, a zero
error will result. If this happens, the load must be removed and the indicator restarted.
Therefore, care should be taken to make sure that the scale platform is empty when the
scale is turned on to insure proper operation of the ZERO button.
In addition, when either "Legal for Trade" mode is selected, the "lb & oz" weight display
mode is disabled, since it is not recognized as a "Legal for Trade" weight display. When
the "Std" mode is selected, the ZERO button and "Auto Zero Tracking" parameter will work
through the full capacity of the scale. The "lb & oz" weight display will also operate
normally, if selected.
