Rice Lake 120 Digital Weight Indicator - Manual (Page 37)

Appendix 33
7.5 Conversion Factors for Secondary Units
The 120 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 units can be specified on the FORMAT
menu using the SECNDR parameter, or by using EDP
commands.
• To configure secondary units using the front
panel menus, use the Table 7-4 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 000050.
Next, use the MULEXP parameter to set the
decimal point position. In the example above,
the conversion factor for pounds to short tons is
actually 0.0005 (2000 lb x 0.0005 = 1 tn). Use
the and keys to shift the decimal point to
show a value of 0.00050.
Another example: If the primary unit is ounces
and the secondary unit is grams, the conversion
factor is 28.3495. To enter this value using the
menus, first enter 283495 for the MULT
parameter, then use the MULEXP parameter to
adjust the decimal point to 28.3495.
• To configure secondary units using EDP
commands, use the Table 7-4 to find the
conversion value for the SEC.MULT and
command. For example, if the primary unit is
pounds and the secondary unit is short tons, send
t h e f o l l o w i n g E D P c o m m a n d t o s e t t h e
multiplier for the secondary units.
SEC.MULT= 0.00050<CR>
• Units of weight other than those listed in
Table 7-4 cannot be directly specified as primary
or secondary units on the 120 indicator. For
unlisted units of weight, specify NONE on the
UNITS parameter.
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 display will overflow.
For example, if the primary units are short tons,
secondary units are pounds, and the secondary
decimal point is set to 8888.88, 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.
