User-Definable Units
USER-DEFINABLE UNITS
User-definable units are units of measure whose conversion factors are determined
by the user. Setra scales have two user-definable units of measure: X and T units.
These units may be used to weigh in dollars (given the weight of one dollar of
substance), length (given the weight of a known length of material), or volume (given
the weight of a known volume of material). Conversion factors can be entered
through the keyboard to be multiplied by the displayed weight, or divisors can be
entered to be divided into the displayed weight.
X UNITS
X units can be directly changed by entering a factor or divisor. To measure in X units,
proceed as follows:
1. Calculate the ratio you wish to enter. If your ratio is in grams per X unit, ounces
per X unit, pounds per X unit, etc., you will enter a divisor. Proceed with Steps 2
through 7.
If your ratio is in X units per gram, X units per ounce, X units per pound, etc.,
you will enter a factor. Proceed with Steps 2 through 7, skipping step 3.
2. Press the
conv
key until the display reads in the known units from which you
wish to convert.
3. If you are entering a divisor, press
—
.
4. Enter the conversion ratio.
5. Press the
conv
key.
6. Place an object on the scale.
7. Wait for the “ok” symbol, then read the display. The reading given is in X units.
