to provide years of service with virtually no
maintenance .The Portable Advanced housing is
constructed of a material which is impact resistant.contains
a one piece solid-state precision electronics
PC board.and a five digit LCD display which
is 0.5 inches in height.All Portable Advanced
balances are initially factory set to measure
in grams and can be set to measure in other
units of measure as desired. Each balance operates
through a series of menus which enable precise
calibration and the selection of various parameters
which enhance operation. A built in lock switch
prevents calibration settings from being changed.
Power is supplied through an AC adapter or batteries.
3. This Portable Advanced balance contains two

8.6.1 Custom Unit Conversion Factor
When you need to display
weight measurements in a weighing
unit Other than those provided
standard with the balance, this
feature can be used to create your
own custom weighing unit. It
permits you to enter a conversion
factor which the balance will use
to convert grams to the desired
unit of measure.
One example is shown at the
end of this section. It illustrates
how to set the conversion factors to
display weight in Grains.
Conversion Weight Weight
Factor × in = in
Grams custom unit(s)
Conversion factors are expressed in scientific
notation and entered into the balance in three
parts:
· A number between 0 and 9 to four decimal
places.
· A power of 10 called the exponent.
· A least significant digit (LSD).
Use the following procedure to enter conversion
factors :
? Access the C. Unit submenu.
? The mantissa of the current conversion factor
will be displayed. This will
13
be a number between 0 and 9.9999 with the first
digit flashing. For conversion factors outside
of this range, the exponent will be used to
FLASHING
move the decimal point.
? Press to change the value
of the first digit.
? When the desired value is FLASHING
displayed, press to accept it and
the nest digit will begin flashing.
? Set the value of all digits in
the same manner.
? After the last digit is entered,
the display will show the current
exponent. The exponent is shown on
the display preceded by the letter E.
There are 7 exponent values which
you can choose from (see table).
? Press to change the
exponent.
? Press to accept the
displayed exponent. When is
released, the display will show the
current least significant digit.
The least significant digit is the digit in
the last decimal place on the display.
The selection you make causes the

8.6.2 (example) Converting to "Grains"
? Determine the number of
grains equal to one gram :
IF 1 grain = 0.0647989 grams
THEN 1 gram = 1 / 0.0647989
? Since the balance displays only 5 OR 1 gram
= 15.43236 grains digits, round the number to
the 5 most
significant digits :
? Using this number, enter the
conversion factor : "15432"
The display will indicate 1 unit for Number
= 1.5432
every grain placed on the platform. E = 1 (to
move the decimal point
one place to the right)
d = 1 (normal setting )
8.7 Averaging Level
Averaging level compensates for vibration or
excessive air currents. During operation, the
balance continually takes weight readings from
the weighing cell. Successive readings are then
digitally processed to achieve a stabilized
display. Use this submenu to specify how much
processing you need to obtain stable results.
NOTE : Averaging level does not affect balance
accuracy.
