11.8 Conversion Factors for Secondary Units
The 720i has the capability to mathematically convert a weight into many different types of units and instantly
display those results with a press of the UNITS key.
Secondary and tertiary units can be specified on the FORMAT menu using the SECNDR and TERTIA parameters,
or by using serial commands.
• To configure secondary or tertiary units using the front panel menus, use the Table 11-9 to find the
conversion multiplier for the MULT parameter. For example, if the primary unit is pounds and the
secondary unit is short tons, set the MULT parameter to 0.000500.
• To configure secondary or tertiary units using serial commands, use the Table 11-9 to find the conversion
multiplier for the SC.SEC.MULT or SC.TER.MULT command. For example, if the primary unit is pounds
and the secondary unit is short tons, send the serial command SC.SEC.MULT= 0.0005 to set the
multiplier for the secondary units.
Note
Ensure that the secondary decimal point position is set appropriately for the scale capacity in the secondary
units. If the converted value requires more digits than are available, the indicator displays an overflow message
(OVERFL).
For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set
to 8888.888, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a
conversion factor of 2000, the secondary units display needs five digits to the left of the decimal point to display
the 10000 lb secondary units value.
