Safety Instruction

WARNING

Calibration, inspection, and maintenance of the indicator must be

performed by a qualified technician.

WARNING

The indicator can be damaged by static

electricity and should be considered sensitive

equipment. Remove power during electrical

connections. Touching internal components by

hand is prohibited.

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.

4

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: 100-240V 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:

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.

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, press to clear the tare weight in

memory. The indicator automatically switches to Gross

mode.

When in Net mode, press 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

pressed 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.

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 pressing

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, press 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

press 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 press 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 ’34.56’. This means the actual weight is 1234.56

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.

3.6 Print and Print Formatting

When the weight is stable, pressing 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

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 press 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.
