7.5 Conversion Factors for Secondary Units
The
320IS
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.
• SEC.MULT only applies if UNITS parameter (SECNDR) is set to NONE.
• To configure secondary units using the front panel, use Table 7-8 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.
You must use the MULT parameter to set the decimal point position. Use the numeric keypad or the
LEFT/
RIGHT
keys to select the digit; Use the
UP/DOWN
keys to increment and decrement (see Figure 3-4 on
page 14).
LEFT/RIGHT
keys also select decimal placement.
• To configure secondary units using EDP commands, use the Table 7-8 to find the conversion multiplier for
the SEC.MULT command. For example, if the primary unit is pounds and the secondary unit is short tons,
send the EDP command SEC.MULT= 0.0005<CR> to set the multiplier for the secondary units.
• Long tons and grains units listed in Table 7-8 cannot be directly specified as primary or secondary units on
the
320IS
indicator. For these or other unlisted units of weight, specify NONE on the UNITS parameter.
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 will display 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
8888.88, 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.
