1. INTRODUCTION

This manual contains installation and operation instructions for the CR Series

Scales. Please read the manual completely before using the scale.

1.1 Safety Precautions

Please follow these safety precautions:



Verify that the AC Adapter input voltage matches the local AC power supply.





Use the scale only in dry locations.

For best results, use the scale in the specified optimum operating temperature.





Do not operate the scale in hostile or unstable environments.

Use your scale with care, gently loading items to be weighed onto the center of the pan. Avoiding rough treatment will aid in the life of your scale.





Indoor use

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

1.2. General Product Features



Power Up test:

When the scale is turned on, all display segments will be displayed for a few seconds, indicating that the unit is self adjusting to zero.

Once the “

0

” is displayed, the scale is ready for use.





Stable Reading indication:

A star indicator will appear in the lower left corner of the display when a stable reading has been reached.

Overload:

If the applied load exceeds the capacity of the scale, an “

E

” will appear on the display and the load should be removed immediately. The scale will return to normal operation.



Tare Function:

Values can progressively be added to a sample. By pressing the button, the scale display returns to zero. After adding

 additional mass, press to zero the scale again. Additional mass may be added up to the capacity of the scale.

Negative Value:

When a load is removed from the scale, any zeroed value will be displayed as a negative number. To return to normal operation, the



 zeroed value can be cancelled by pressing button.

Low Battery Indication:

The display will show “

Lo

” when the batteries are weak and need to be replaced.

Auto Shut-Off:

To extend battery life, the scale will automatically turn off after approximately (4) minutes if no active weighing is occurring. This feature is active with battery operation only.

2. INSTALLATION

2.1 Transportation Protection (0.1g model only)

Remove the plastic transportation protective insert for use. Save the plastic insert to ensure safe transport.

2.2 Power

Power the scale using the AC power adapter (not included) or 3 AA batteries.

Battery Installation

Remove the battery cover on the bottom of the scale and place the 3 “AA” size batteries into the compartment as indicated. Do not use excessive force or press the weighing pan. Re insert the battery cover.

AC Power Connection

Connect the AC adapter (not included) to the receptacle at the rear of the scale.

Plug the AC adapter into a properly grounded electrical outlet.

The scale base allows for the efficient stacking of one scale on top of another.

Note:

do not stack more that 4 scales on top of each other.

3. OPERATION

3.1 Two Button Keypad



:

Pressing this button turns on the scale. This same button operates the zero feature when the scale is on. Press and hold this button for three seconds to turn the scale off.



:

Press this button briefly to change the weighing unit. Press and hold this button to begin the calibration process.

3.2 Calibration

For best results calibrate the scale at regular intervals. This is especially important if the scale is in use for prolonged periods.

Calibration weights are not provided with the scale



Press and hold the button to start the calibration process. The display will show

CAL

.



The calibration process can be aborted by turning the scale off.



Press the button to capture 0. The display shows

-C- while the scale stores the zero load signal.



The display will show

C

xxx where xxx is the calibration weight in grams.



Place the appropriate calibration weight on the platform.



Press the button.



The display shows

-C- while the scale stores the calibration point signal.



After calibration, the display returns to the normal weighing mode.

The message

CAL E

will appear if the calibration steps are not followed or the wrong weight was used.
