1.0 OPERATION

1.1 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 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 and you are now in Setup & Calibration mode.

Note: 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.

TARE 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.

Lb/kg Toggles the display between pounds and kilograms.

1.2 Error Messages:

ScnEg When the weight is more than 10 divisions negative from the zero

calibration point.

OLD The scale is in an overload condition.

BAtLo Will flash when the battery voltage falls to 10.8VDC and will be

displayed constantly when the voltage falls to 10.2VDC.

Err d More than 5000 scale divisions have been selected in S1 Ntep or S1

Angle mode. More than 20,000 scale divisions have been selected in

S1 No Mode.

1.3 Numeric Entries:

Once you have entered Setup and Calibration mode, (as described on the previous

page) some entries may require entering a numeric value.

To enter a numeric value:

1. Press and release the lb/kg key to move into the desired menu field.

2. Press and release the ZERO key, the first digit will begin to flash.

3. Use the up and down arrow keys to increase or decrease the value of this
digit until you reach the desired value.

4. Press the TARE key to move to the next digit and repeat step 3.

When you are satisfied with the value of each digit press the PRINT/ENTER key to

save your entry and return to the menu.

1.4 Setup Parameters:

To begin 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 and you are now in Setup

& Calibration mode.

Note: P xxx and C xxx are event counters that will increment each time one or more
Changes are made to the scale Scale or Calibration Parameters.

With the display indicating ScAlE, press the GRS/NET key to move down to change a
parameter. This allows the operator to change any one of the Scale Parameters S1 thru S18. 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 begin flashing. Enter the new capacity
using the steps described in section 1.4 shown at the top of the page. Once you have the capacity
entered, press the PRINT/ENTER key to enter the value and return to S2.

The same steps can be followed to enter the count by. Press the GRS/NET key to move
down until S3 is displayed. Press the lb/kg key to move right into the S3 parameter. The current
Count By will be displayed. Use the up and down arrow keys to increase or decrease the value.
Use the left and right arrow keys to adjust the decimal point. When the desired Count By is
entered, press the PRINT/ENTER key to enter the value and return to S3.
