METER CONNECTIONS
To connect power via AC wall adapter cable to the CSW-20AT meter. First make sure the
On/Off switch on the rear of the meter is in the off position. Connect the wall adapter to your
110VAC outlet. Next, connect the other end of the cable to the connector on the rear of the indicator.

1.0 OPERATION
1.2 Key Functions:
Numeric Keys (0-9, .)
ZERO
Used to enter numeric values and choices.
Brings the scale to a zero balance reading. If the ZERO key is pressed and held for 5 seconds the Calibration zero value will be displayed.
GRS/NET Toggles the display between Gross weight and Net weight.
This key is also used to enter Setup & Calibration Mode.
To enter press and hold this key until the Parameter ( P xxx )
Event counter is displayed, then release. Immediately after
CodE is displayed, enter in sequence (within 5 seconds) TARE , lb/kg , GRS/NET , and PRINT/ENTER . The display will indicate ScAlE .
Note: P xxx and C xxx are event counters that will
TARE increment each time one or more changes are made to the Scale or Calibration Parameters.
Enter Tare weights by applying a load to the scale, then press the tare key. A Tare weight may also be entered by using the numeric keys to enter a value, then press Tare.
Note: If Ntep or Angle is enabled the tare can only be keyed in when the displayed weight is in the zero band.
If Non-Ntep is enabled the Tare can be entered anytime.
To view the current Tare value, press and hold the TARE key for 3 second. Clearing a Tare can be completed by entering a 0 and then pressing the TARE key or by pressing the ZERO key.
Lb/kg
PIECE COUNTING
Toggles the display between pounds and kilograms.
When adding piece weight, use the numeric keypad to enter the weight value (with a decimal place) then press Piece/count . When adding the number of pieces, use the numeric keypad to enter a whole number (with no decimal place then press the Piece/Count key. Pressing the Piece/Count key will toggle between pieces and the average piece weight display.
PIECE COUNTING Press GRS/NET to switch to weighing mode and PIECE/COUNT key to view the piece count. Enter 0 and press PIECE/COUNT to clear the piece weight.
TOTAL With a weight on the scale press the TOTAL key to total the weight.
Enter 0 and press the TOTAL key to display the current total. When
TOTAL is pressed while the displayed weight is in the zero band, the current total will be displayed, printed and cleared.

1.2 Key Functions Continued:
ID When the ID key is pressed, the last 6 digits of an ID number will be displayed. To clear an ID number press ID then while the current ID number is displayed press Zero. To enter a new ID number, press the ID key and enter a value up to 20 digits then press
PRINT/ENTER . If a barcode scan is received on COM2 (02h, up to
20 ASCII characters, 0dh, 0ah) the alphanumeric value will be stored in the ID. The ID No. will be cleared after the total is cleared or ZERO is pressed. ID No. will be printed just under the time and date. If the ID No. is “0” this line will not be printed.
SET/POINT
(Optional)
Press the SET/POINT key then the up arrow, to set the upper limit.
Set hi will be displayed then “0” will be displayed. Using the numeric keypad, enter the desired value and press the
PRINT/ENTER key. Press the SET/POINT key then the up arrow, to set the lower limit. Set Lo will be displayed then “0” will be displayed. Using the numeric keypad, enter the desired value and press the PRINT/ENTER key.
If “0” is entered for the upper or lower limit, the Setpoint option will be disabled.

3.0 CALIBRATION PROCEDURE:
3.1 Calibration Menu Definitions:
C1 Zero All Raw counts, (Pitch and Roll if in angle mode) will be
displayed. When ZERO is pressed an analog zero is done
and all calibration span points will be cleared.
If the indicator is in angle mode the Pitch and Roll offsets
will also be Zeroed.
C2 Zero Zeroed raw counts, (Pitch and Roll if in angle mode) will be
displayed. When ZERO is pressed an analog zero is done
and all calibration span points will NOT be cleared.
If the indicator is in angle mode the Pitch and Roll offsets
will be Zeroed.
C3 Span Point The last Calibration weight will be displayed then the actual
weight on the scale will be displayed.
If you do not wish to change the span point, press the TARE
key to exit without making any changes .
If the displayed weight does not match the known test
weight, use the numeric keypad to enter the correct weight.
Press the PRINT/ENTER key to save and exit. The display
will return to C3.
C4-C7 Span Points C4 to C7 are for linearity correction. They can be used in
order and in any quantity or not at all if no correction is
necessary.
C4 to C7 may be entered at any time without affecting the
original calibration points.
The last calibration weight will be displayed then the actual
weight on the scale will be displayed. If no calibration weight has been entered at this span point “ notset ” will be
displayed then the actual weight on the scale is displayed.
If the displayed weight does not match the known test
weight, follow the steps described for C3 Span Point on
adjusting the weight and entering the value.
11
3.2 Calibration:
Press and hold the GRS/NET key, as described previously in section 2.2. ScAlE will be displayed. Press the lb/kg key to move right until CalIb is displayed. Press the
GRS/NET key to move down, C1 will be displayed. Press the lb/kg key to move right,
The raw counts will be displayed. With no weight on the scale and the scale level, press the ZERO key, “0” will be displayed. Press the PRINT/ENTER key to save the entry. “0” is now entered and the display will return to C1 .
Note: With the scale completely level use C1 or C2 to zero the angles. There is
No need to use both C1 and C2.
Press the GRS/NET key to move down until C3 is displayed. Press the lb/kg key to enter. The last calibrated weight will flash then the current weight on the scale is displayed. Place a known test weight on the scale, with the scale level. Using the numeric keypad, enter the actual weight and press the PRINT/ENTER key to save and exit. The display will return to C3 .
3.3 Linearity Correction:
If Linearity Correction is needed, Press the GRS/NET key (from the Calibration menu) to move down until C4 is displayed. Press the lb/kg key to move right, the last calibrated weight will flash or “ notset ” will flash if this point has not been previously set.
Next the current weight on the scale will be displayed. Place a different known test weight
(not the same test weight that was used for C3) on the scale. Using the numeric keypad, enter the actual weight and press the PRINT/ENTER key to save and exit. The display will return to C4 . Repeat these steps for C5 , C6 and C7 .
Linearity Correction points ( C4-C7 ) can be used in any order and in any quantity or not at all if no correction is necessary. After calibration is complete you may return to these correction points and make changes to its value without affecting any of the original calibration points.
