1. INTRODUCTION
This manual contains installation and operation instructions for the CompassTM CX
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 “ ” 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.
