4 Section 1. Instruction This weighing indicator is designed for use with bench or floor scales. Its basic weighing functions include: Zero, Tare, Gross/Net, Hold, Print, kg/lb conversion and Total (accumulation). 1.1 Battery Instruction (Optional) 1. When first using the internal battery, charge the battery fully, to prevent low voltage resulting from the self-leakage of battery. 2. A flashing Red light means low battery. 3. The Red light turns on during charging. 4. The light turns Green when fully charged. 5. If the battery is not used for long periods of time, take it out to avoid the leakage. 6. For best results, fully discharge the battery every month (using the indicator until automatically powers off. 3

5 Section 2. Installation and Calibration Your scale is pre-calibrated at the factory and only requires the load cell cable to be connected from the base to the indicator. The following information is provided for a qualified service technician only. 2.1 Power Supply The indicator is powered by plugging the adapter directly into the DC Power connector located at the bottom of the indicator. Power Input: V 50/60Hz 1.6A Power Output: 9.0V 1.2A Polarity: Center Positive Approvals: ULc and ULus 2.2 Connecting Load Cell and Indicator The indicator can be used with either 4- or 6-wire 350Ω load cells. Quick Disconnect Pinout: 4

6 Section 3. Operation Front Panel LED Indicators Functions when Activated kg Weighing in Kilograms Tare A Tare weight is present lb Weighing in Pounds Weight is stable Hold Indicates a held weight 0 Zero weight confirmation Gross Gross weight is displayed Total Go to accumulation mode Net Net weight is displayed Battery AC is present or indicates optional battery charge level. 5

7 Function Press to print current weight. Zero the displayed weight. Press to tare any non-negative displayed weight. The indicator automatically switches to NET mode. When in Net mode, to clear the tare weight in memory. The indicator automatically switches to Gross mode. When in Net mode, to display the gross weight. The displayed weight will automatically switch back to Net mode after three seconds. Toggles between lb and kg units. Holds the most current weight value on the display until ed again. (see C11 for settings) 1. Accumulation 2. Works together with Print to perform the accumulation function and check the accumulation result Turns the indicator On and Off. Hold for 2 seconds to power Off. 6

8 3.3 Zero operation 1. Initial zero When the indicator powers up it will automatically zero out 10% of the scale capacity. If this is not desired, change parameter C21 to the desired setting. 2. Manual Zero You can zero up to 100% of the scale capacity by ing ZERO. 3.4 Tare operation Press TARE key, the displayed weight is tared. The indicator then displays a zero Net weight and activates the NET and TARE status lights. In Net mode, TARE key to clear the tare weight. The indicator will then enter the Gross mode. 3.5 Accumulation operation Place the item on the scale and wait until stable, Press TOTAL to enter accumulation mode, the TOTAL indicator will turn on and the display will show the count n001 to confirm the item was accumulated. Remove the item from the platform and allow the scale to return to zero. Place the second item on the platform. When the weight is stable TOTAL, n002 is displayed. Repeat until complete. You can accumulate a maximum of 999 items. Display the accumulated weight --- Press and hold the PRINT key; then the TOTAL key, display n***, to display the counter value and then the total weight. There are 8 digits in total. It will show the first 4 digits then the last 4 digits. For example, the first 4 digits is 0012, and the last 4 digits is This means the actual weight is EXIT the accumulation function --- When the indicator shows the last 4 digits, Press and hold TOTAL, the indicator will show clr n. To exit without clearing the accumulator: Press PRINT. To exit and clear the accumulator: Press ZERO and clr y will be displayed. Then Press PRINT. 7

9 3.6 Print and Print Formatting When the weight is stable, ing PRINT will print the displayed weight. Note: When printing in tare mode, if the weight is negative, it will not print. Set C30 for the desired date format. Tare mode Gross mode Date: XX.XX.XX Date: XX.XX.XX Time: XX:XX:XX Time: XX:XX:XX NET XX.X kg GROSS XXX.X kg TARE XX.X kg GROSS XXX.X kg 8

10 Section 4. Calibration and Parameters The following information is provided for a qualified service technicians only. Calibration of the scale requires the use of certified weights. Any alteration of the settings and/or calibration may require a service call by a certified technician that is not covered under the warranty. 4.1 Enter Calibration 1. Press and hold PRINT, then HOLD to enter calibration. 2. If this procedure does not enter calibration, remove the rear cover and locate the switch on the lower left of the circuit board labeled MARK. This switch must be in the ON position to enter calibration. Once turned on, repeat step 1 above. NOTE: If the indicator has an NTEP seal and a lead and wire seal, an authorized technician must perform this work so the legal for trade status with local weights and measures authorities is not affected. Button PRINT ZERO TARE HOLD LB/KG GROSS COUNT Calibration Function ENTER UP DOWN BACK LEFT RIGHT Description of Function Accept parameter value and scroll to next parameter. Also (where applicable) moves to the next value within a single parameter. Change parameter value Change parameter value Scroll to previous parameter Use to select parameter digit (C##, C#_, C_#). Scroll digit values using Up and Down arrows. Press Enter to advance to that parameter. Exit calibration and save changes ON/OFF POWER 9
