1. INTRODUCTION
The CTG series of scales provides an accurate, fast and versatile
series of general purpose weighing scales with counting, % weighing and
check-weighing functions.
There are 4 models in this series, with capacities up to 30 kg, they all
have stainless steel weighing platforms on an ABS base assembly, all the
keypads are sealed, color coded membrane switches and the displays
are large easy to read liquid crystal type displays (LCD). The LCDās are
supplied with a backlight.
All units include automatic zero tracking, audible alarm for pre-set
weights and an accumulation facility that allows the count to be stored
and recalled as an accumulated total.
2. KEY DESCRIPTIONS
Zero or
Set the zero point for all subsequent weighing. The display shows
zero.
A secondary function , of "Enter" key when setting parameters
or other functions.
Tare or
Tares the scale. Stores the current weight in memory as a tare value,
subtracts the tare value from the weight and shows the results. This is the
net weight.
A secondary function , of incrementing the active digit when
setting a value for parameters or other functions.
Lim or or CHK
Sets the limits for check weighing. Allows setting of either the low
limit or the high limit or both.
Secondary function , is to move the active digit to the right when
setting values for parameters or other functions.
-1-
%
Enters the percent weighing function. Allows the
weight, unit weight, and count to be seen when parts counting.
Secondary function , is to move the active digit to the left when
setting values for parameters or other functions.
Func or or F
Used to select the function of the scale. If the scale is weighing it
will select parts counting. Of it is not in weighing mode it will return the
user to weighing.
Secondary function ( C ) , is to act as a clear key when setting values
for parameters or other functions.
Print or
To print the results to a PC or printer using the optional RS-232
interface. It also adds the value to the accumulation memory if the
accumulation function is not automatic.
Secondary function (ESC) , is to return to normal operation when the
scale is in a parameter setting mode.
U or UNIT
This key will select either kilograms, pounds, ounce for the weighing
unit.
3. OPERATION
3. 1 ZEROING THE DISPLAY
You can press the ZERO key at any time to set the zero point from
which all other weighing and counting is measured, within 4% of power
up zero. This will usually only be necessary when the platform is empty.
When the zero point is obtained the display will show the indicator for
zero.
The scale has an automatic rezeroing function to account for minor
drifting or accumulation of material on the platform. However you may
need to press the ZERO key to rezero the scale if small amounts of
weight are shown when the platform is empty.
