2. INTRODUCTION

The ROW series precision balance that amplifies signals from a load cell,

converts it to digital data and displays it as a mass value.

It is suitable for general weighing or more specialized applications such as

check weighing, animal weighing and accumulation applications.

It can connect the indicator to a printer or a PC.

Large LCD with white LED back light display

3. INSTALLATION

Unpacking

When you receive the balance, inspect it to make sure that it is not damaged and

that all are parts are included:

Remove the Indicator from the carton.

Remove the protective covering. Store the packaging and to use if you

need to transport the scale later.

Inspect the indicator for damage.

Make sure all components are included.

2. Adaptor

3. Manual

Installation

Place the balance on a table or connect with proper stand.

Connect the plat form load cell cable in to the indicator load cell connecter.

Load cell connecter is locating back side of the balance.

Connect the adaptor pin in to the indicator adaptor jack.

Adaptor jack is locating, back side of the balance.

Adaptor connects into your AC power socket.

Pluggable equipment must be installed near an easily accessible socket

outlet with a protective ground/ earth contact.

Turn on the On/Off key. If you want to turn off, press the key again.

Display will be show the scale capacity and will be starting self-checking.

After self-checking, display will be come to normal weighing mode.

Warm-up time of 15 minutes stabilizes the measured values after

switching on.

Calibrate with exact calibration weights, minimum 1/3 of the scale capacity

want to use for calibration. For calibration see details in parameter.

Then you can start your operation

Connect Adaptor and Charging

To charge the battery insert the adaptor pin to jack. Adaptor simply plug into

the mains power. The scale no needs to be turned on.

The battery should be charged 12 hours for full capacity.

The symbol status of the battery

Battery voltage has dropped

Low voltage

Fully charged

Do not use any other type of power adaptor than the one supplied with the

scale.

Verify that the AC power socket outlet is properly protected.

Note: Please charge the battery before using the scale for the first time.

FUNCTION

Turn the power On/ Off

Used to reset to Zero. In setting mode can use to confirm entry

Used to recording tare values and change the value from gross

value to net value.

Insetting mode can use to increase the value and scroll

forward in menu.

When the scale has been tared and display is in gross or net

mode.

When using the settings mode, can use to move active digits

right.

For print the results, to the PC or printer using the optional RS-

232 interface.

It also adds the value to the accumulation memory if the

accumulation function is not automatic.

When using the settings mode,can use to clear active digits

Switch to unit weight. In setting mode,

escape back to menu/ weighing mode.

When using the settings mode, can use to move active digits

left.

5. OPERATION

Initial Start – Up:

Warm-up time of 15 minutes stabilizes the measured values after switching on.

5.1. Power ON/OFF:

Switch on the balance by pressing key.

The display is switched on and the test is started and if want to switched

off, press again the key.

5.2. Zero

Environmental conditions can lead to the balance exactly zero in spite of

the platform not taking any strain. However, you can set the display of

your balance to zero any time by pressing key and therefore ensure

that the weighing starts at zero.

5.3. Tare

The weight of any container can be tared by pressing button so that

with subsequent weighing the net weight of the object being weighed is

always displayed.

Load weight on the platform.

Press key. Zero is displayed, and tare is subtracted.

Remove weight on the platform. Tared weight is displayed. It can set only

one tare value. It can display with a minus value.

Press G/N to change between gross weight and net weight.

To clear the tare value, remove the load and press key. Zero is

displayed, tare weight is cleared.

5.4. Sample weighing

Place goods to be weighed on the platform.

Wait few seconds for stability display.

Read the result.

Avoid overloading. When display appears “ol” reduce the load or

unload.

5.5. Check Weighing
