2 Outline and Features
The HW-G series is a platform scale with a minimum resolution of 1/10000 .
Type L scales have an LCD (Liquid Crystal Display) and use batteries as a power
source to provide portability. This type can also use an AC mains adaptor.
Type V scales have a fluorescent display so the weighing value can be read in
dim light. This type uses the AC power line as a power source.
The base unit (platform) is water-resistant in accordance with IP-65
specifications.
The counting mode function converts the total mass value (total weight) of articles
to a count, assuming all items to have the same mass.
The percentage mode function displays the mass of an item as a percentage of a
stored 100% mass.
The accumulation function accumulates each weighing value and counts the
number of weighings.
The comparator function compares the display value with the upper limit value
(HI) and the lower limit value (LO) and displays the result. The result can output if
option OP-03 is installed.
The simple batch function or full/dribble batch function can be used for filling to a
target mass value. The status of a weighing value can be output if option OP-03
or OP-04 is installed. The outputs are Zero Band, Preliminary and Final.
The optional RS-422/RS-485 serial interface can control up to 16 scales from a
computer when this option is installed in place of the standard RS-232C serial
interface.
Type V scales can be equipped with option OP-06, a built-in impact dot matrix
printer.

11 Comparator Function
This function compares a display value with the upper limit (HI) and the lower limit (LO)
and displays these results.
It is necessary to set the “comparator function ( f6 0 ~ f6 7 )” parameters, upper limit
value (HI) and lower limit value (LO) in the function table, in advance to use this function.
It is necessary to install option OP-03 or OP-04, if you use the relay output of the
comparator.
Comparator Sign
Comparison results are displayed by indicators
Comparison Condition
weighing value < lower limit value LO is displayed and output.
lower limit value < weighing value < upper limit value OK is displayed and output.
upper limit value < weighing value HI is displayed and output.
Parameter List and Word Definition
The “ near-zero “ is within ±4 digits from the zero point in the unit of kg.
The “digit” is a unit of display, and is equivalent to the minimum graduation.
The “zero point” is the fundamental starting point to weighing.
Function table Meaning and Purpose
f6 0 Having pressed the SET switch, the scale will always compare the
current display value.
f6 1 The scale always compares the display value.
f6 2 Pressing the SET switch the scale always compares the display value
if not near-zero.
f6 3 The scale always compares the display value if not near-zero.
f6 4 When the display value becomes stable after pressing the SET
switch, the scale compares the display value. If the SET switch is
pressed again the scale stops the comparison.
f6 5 When the display value is stable the scale compares the display
value. It does not compare on an unstable condition.
f6 6 When the display value becomes stable while not near-zero, after
pressing the SET switch, the scale compares the display value. It
does not compare on an unstable condition. If the SET switch is
pressed again the scale stops the comparison.
f6 7 When the display value becomes stable and not near-zero, the scale
compares the value.
Caution
The upper limit value (HI) must be equal to or greater than the lower limit value (LO).
The parameters of the upper limit value (HI) and the final value (HI) use the same memory.
The parameters of the lower limit value (LO) and the zero band (LO) use the same memory.
The upper/lower comparator function, the simple batch function and the full/dribble batch
function cannot be used at the same time because these parameters use common memory.
