1. INTRODUCTION
This manual contains installation, operation and maintenance instructions for the BC Series counting scale. Please read the manual completely before installation and operation.
1.1 Product Description
The BC Series is an economical compact counting scale designed for fast, accurate operation ideally suited for annual inventories, parts rooms, rentals and other counting applications. Combining an internal accuracy of 1:600,000, Average Piece Weight (APW) of
0.01g to 0.1g (depending on model) and an internal rechargeable battery, the Ohaus BC Series scale offers accuracy, durability and portability in one easy-to-use design.
1.2 General Features
5 Capacity models: 3kg, 6kg, 15kg, 30kg with maximum displayed resolution of 1:30,000 5 Stainless steel weighing pan 5 Durable plastic housing with protective cover 5 3-window, backlit LCD with prominent 19mm high digits 5 Fast display of Weight, Average Piece Weight (APW) and Parts Count. 5 Gram or pound weighing units 5 Low sample weight and APW indication 5 Full counting keypad with numeric keys 5 Dedicated TARE and SAMPLE keys for simple and fast operation 5 Accumulator function for weight and parts count 5 User-programmable parts checking mode with HI/LO settings and audible buzzer 5 Adjustable filtering level for weighing under various conditions 5 Auto-optimization recalculates APW constantly for enhanced counting accuracy 5 10-APW memory locations 5 80-hour Internal rechargeable battery with power-saving Auto-shut off feature
1.3 Safety Precautions
For safe and dependable operation of this scale, please comply with the following safety precautions:
5 Verify that the input voltage printed on the AC Adapter and the plug type matches the
local AC power supply.
5 Make sure that the power cord does not pose a potential obstacle or tripping hazard. 5 Disconnect the scale from the power supply when cleaning the scale. 5 Do not operate the scale in hazardous or unstable environments. 5 Do not immerse the scale in water or other liquids. 5 Do not drop loads on the platform. 5 Use only approved accessories and peripherals, as available. 5 Operate the scale only under ambient conditions specified in these instructions. 5 Service should be performed by authorized personnel only.

2. INSTALLATION
2.1 Unpacking
Unpack and verify that the following components have been included:
5 BC Scale 5 Weighing Platform (plastic base with stainless steel pan) 5 Instruction Manual 5 AC Adapter
Save the packaging material. This packaging ensures the best possible protection for the storage or transport of the product.
2.2 Installing Components
Position the weighing platform pins into the through-holes on the top housing, then set the platform securely into place.
IMPORTANT:
5 BEFORE USING THE SCALE, REMOVE THE SHIPPING PROTECTION SCREW
located underneath the scale. This screw ensures protection of the load cell during transport, but will need to be removed for the scale to operate properly.
5 Install the protective screw if transporting the scale.
5 It is recommended that the protective screw be re-installed if transporting the scale.
Do not over-tighten the protective screw as it may damage the load cell. To re-install, turn the scale on and place a 500g weight on the pan, then slowly screw in the protection screw until the display shows a value between 250g to 400g.
2.3 Selecting the Location
Operate the scale on a firm, level surface. Avoid locations with rapid temperature changes, excessive dust, moisture, air currents, vibrations, electromagnetic fields, heat or direct sunlight.
2.4 Leveling the Scale
Adjust the leveling feet until the bubble is centered in the circle of the level indicator (located on the front panel).
NOTE: Ensure that the scale is level each time its location is changed.
Page 6
BC Series EN-4
2.5 Connecting Power
2.5.1 AC Power
Verify that the intended AC power source matches the AC adapter rating. Connect the supplied AC adapter to the power input receptacle underneath the scale. Plug the AC adapter into a properly grounded power outlet.
2.5.2 Battery Power
The battery will begin charging with the AC adapter connected accordingly. An LED indicator below and to the right of the Count window shows the status of battery charging:
Green – battery is fully charged
Yellow – battery is partially charged and charging
Red – battery is nearly discharged
When AC power is not available, the scale will operate on the internal rechargeable battery. The scale will automatically switch to battery operation if there is a power failure or the power cord is removed. Low battery charge is indicated by the
annunciator (the scale
will operate for approximately 10 hours more before automatically switching off).
Before using the scale for the first time, the internal rechargeable battery should be fully charged for up to 12 hours. A fully charged battery can operate the scale for approximately 80 hours independent of AC power. The scale can be operated during the charging process. The battery is protected against overcharging and the scale can remain connected to the AC power line.
NOTES:
5 The battery must be recharged every 3 months if the scale is not used for a long time. 5 Dispose of the lead acid battery according to local laws and regulations.
CAUTION
BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED OHAUS SERVICE DEALER. RISK OF EXPLOSION CAN OCCUR IF REPLACED WITH THE WRONG TYPE OR CONNECTED
IMPROPERLY.
2.6 Initial Calibration
When the scale is operated for the first time, a Span Calibration is recommended to ensure accurate weighing results. Before performing the calibration, be sure to have the appropriate calibration weights.
Refer to Section 6 for Span Calibration procedures.

6. CALIBRATION
For best results, calibrate the scale at regular intervals. Temperature changes, geographic gravity variations, altitude changes and abuse are few reasons why a scale may need recalibration.
When the scale is ideally positioned for operation, enter calibration and proceed as follows:

Long-press Zero to initiate calibration (do not release key-press until “CAL” is displayed).
The required calibration weight is displayed (ex. 3000g for a 3kg model). At this time, a different calibration weight value can be entered via the numeric keypad.
Place the corresponding calibration weight on the pan. The display flashes until the actual weight is registered and the calibration process ends (the scale momentarily beeps before exiting to normal weighing mode).

7. TROUBLESHOOTING
The following table lists common problems, possible causes and remedies. If the problem persists, contact Ohaus or your authorized Ohaus dealer.
Symptom Possible Causes Remedy
Scale will not turn on. AC power not connected.
Battery discharged.
Connect scale to power. Connect scale to power and charge
battery.
Battery fails to charge fully. Battery is defective or past its useful
life.
Have the battery replaced by an authorized Ohaus service dealer.
Weight reading does not stabilize.
Unstable environment. Interference under pan.
Ensure a stable environment. Ensure that the weighing pan is
unobstructed and free to move.
Scale does not display accurately.
Improper calibration. Calibrate the scale using proper
calibration weights.
E1, E2, E3 displayed The pan is placed incorrectly.
Zero limit exceeded during power up.
Reposition the pan correctly. Ensure the pan is empty before
switching the scale on.
--OL-- displayed Load exceeds scale capacity. Reduce the load on the pan.
