SECTION 1 INTRODUCTION
The T2200P series of weighing indicator provides an accurate, fast and versatile
series of general purpose weighing indicator with counting and check-weighing
functions. There are 2 series of indicator within the range.
All the keypads are sealed, color coded membrane switches and the displays are
large easy to read liquid crystal type displays (LCD). The LCD’s are supplied with a
backlight.
All units include automatic zero tracking, audible alarm for pre-set weights, automatic
tare, and an accumulation facility that allows the individual weights to be stored and
recalled as an accumulated total.

SECTION3INSTALLATION
The weighing indicator should be sited in a location that will not degrade the
accuracy.
Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning
vents.
Avoid unsuitable tables. The tables or floor must be rigid and not vibrate. Do not
place near vibrating machinery.
Avoid unstable power sources. Do not use near large users of electricity such as
welding equipment or large motors.
Avoid high humidity that might cause condensation. Avoid direct contact with water.
Do not spray or immerse the scales in water.
Keep the weighing indicator clean.
Verify the voltage showing on the label matches the voltage in your area.
Attach the mains cable to the connector on the side of the indicator. The power
switch is located next to he mains inlet.
Load cell connect as below( 9 pin D-sub connecter)

SECTION4KEYDESCRIPTIONS
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. Entering a
value using the keypad will store that value as the tare value.
A secondary function ▲, of incrementing the active digit when setting a value for
parameters or other functions.
SHIFT or
Selects the data to be displayed when parts counting and is used for other functions
during setting modes. Will move the active digit to the right when setting values
for some functions.
SMPL or
Select sample quantities when parts counting. Move the active digit left when
setting values for other functions.
FUNC or SET
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.
Uor UNIT

SECTION6OPERATION
6.1 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.
6.2 Taring
Zero the scale by pressing the ZERO key if necessary. The zero indicator will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale. The weight that was displayed is stored as the
tare value and that value is subtracted from the display, leaving zero on the display.
The "TARE" indicator will be on. As product is added only the weight of the product
will be shown. The scale could be tared a second time if another type of product was
to be added to the first one. Again only the weight that is added after taring will be
displayed.
When the container is removed a negative value will be shown. If the scale was tared
just before removing the container this value is the gross weight of the container plus
all product that was removed. The zero indicator will also be on because the platform
is back to the same condition it was when the ZERO key was last pressed.
6.3 Weighing a sample
To determine the weight of a sample first tare the empty container then place the
sample in the container. the display will show the weight and the units of weight
currently in use.
6.4 Parts Counting
When the scale is showing weight, pressing the SMPL key will start the parts
counting function.
Before beginning, tare the weight of any container that will be used, leaving the
empty container on the scale. Place the number of samples on the scale. The
