Key Functions:

ZERO 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

TARE

Toggles the display between Gross weight and Net weight.

This Key is also used to enter setup mode. Begin by pressing and holding this key until the Parameter ( Pxxx ) Event counter is displayed, then release. Immediately after COdE is displayed enter in sequence (within 5 sec) Tare , lb/kg

Print/Enter The display will indicate ScAlE .

, GRS/NET , and

-P xxx and C xxx are event counters that will increment each time one or more changes are made to the scale or Calibration Parameters.

Enters the Gross weight value into the Tare display and

switches to the Net display mode.

If the Tare key is pressed and held for 5 seconds the current Tare value will be displayed.

Toggles the display between pounds and kilograms.

lb/kg

PRINT Outputs the displayed weight data to the RS-232 Port.

Note: All keys are disabled when the scale is in motion or overload.

1.2 Error Messages

2.4 Numeric Entries

When entering a numeric value, f irst press and release the lb/kg key to move right into the menu where the numeric value will be entered. Then press and release the Zero key, the first digit in the value will flash. Press and release the

ZERO and GRS/NET keys to increase or decrease the digits value. Press and release the Tare key to move to the next digit. Repeat the steps above to adjust the digits value. Repeat all steps until the numeric value is correct, then press and release the PRINT key to enter the data. The display will return to the menu.

2.5 Set Up Parameters

To begin press and hold the GRS/NET key until the Parameter ( Pxxx ), Event counter is displayed, then release. Immediat e ly after COdE is displayed, (within 5 sec.) enter in sequence indicate ScAlE .

Tare , l b/kg , GRS/NET , and Print/Enter , The display will

-P xxx and C xxx are event counters that will increment each time one or more changes are made to the Scale or Calibration Parameters.

With the display indicating ScAlE , press the GRS/NET key to move down. This allows the operator to change any of the scale parameter S1 thru S1 7 . For example

Press the GRS/NET key to move down until S2 is displayed, S2 is used to set the capacity of the scale. Press the lb/kg key to move right into the S2 Parameter. The current capacity will be displayed. Press the ZERO key, the first digit will flash. Enter the new capacity using the steps described in the above section 2.4. When the capacity is correct, press the Print key to enter the value. The display will return to S2 .

Entering the Count By. Press the GRS/NET to move down, S3 will be displayed.

Press the lb/kg key to move right into this parameter. The current "Count by" will be displayed. Press the ZERO and GRS/NET keys to adjust the divisions. Press the TARE and lb/kg keys to adjust the decimal point. Press the PRINT key, when finished, t o enter the data. The display will return to S3 . Exit Set up Mode By pressing the TARE key, End will be displayed, then press PRINT/ENTER .

Calibration

Menu Definitions

:

C

1 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 in angle mode the pitch and roll offsets will also be zeroed.

C

2 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 in angle mode the pitch and roll offsets will also be zeroed.

C

3 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, press the ZERO key to enter the correct weight.

Use the steps d e scribed in section 1.4 for numeric entry.

When the weight is correct press the Print key to enter the new value.

C4 to 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.

You may also return to C4 to C7 later and add a new

correction point without affecting any 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.

3.2 Calibration

Press and hold the GRS/NET key as d e scribed p reviously in section 2.5. ScAlE will be displayed. Press the lb/kg key to move right, CALib will be 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 button, “0” will be displayed. Press the PRINT key to enter the data. “0” is now entered and the display returns to C1 .

Note: With the scale completely level use C1 or C2 to zero. There is no need to use both C1 and C2.

Press GRS/NET key to move down, C3 will be displayed. Press the lb/kg key to move to the right, 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 forks level. Press the ZERO key, the first digit of the weight will flash. Use the ZERO and GRS/NET keys to increase or decrease the digits value. Press the TARE key to move left, the next digit will flash. Repeat the steps until the correct weight is entered. Press the

PRINT key to record the data. The display will return to C3 .

Press the GRS/NET key until End is displayed, then Press PRINT . Calibration is now complete.

3.3 Linearity Correction

If Linearity Correction is needed, Press the GRS/NET key (from the calibration menu) to move down to C4 . 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 known test weight on the scale with the forks level. Press the ZERO Key for the first digit of the displayed weight to flash. Enter the weight as described in section 1.4, then press the PRINT key to record the data. Continue 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 also return to these correction points and make changes to its value without affecting any of the original calibration points.
