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.

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

It can set an upper or lower limit when weighing with the limits range.
During the limit controls dividing the unit will indicate whether a value
upper or lower limits with an alarm sound . For details see the parameter F3 oFF.
Check mode 1: No beep sound in the limits. Function turned off.
Check mode 2: When the weight is between the limits.OK will shown and
beeper will be sounded.
Check mode 3: When the weight is out of the limits, the beeper will be
sounded and OK will shown.
5.6. Enter to Menu
In the weighing mode, press and together.
Display will be appear
5.7. Set limits
Press to enter the function.
Press key to select the limit.

Select desired setting by pressing and press key to confirm, press
to escape.
Note: The load weight must greater than 20 scale divisions for the check
weighing operations.
To disable the check weighing function, enter zero into both limits.
5.9. Accumulation
To enable accumulation function, select parameter F5 ACC >ACC on
Place the goods on the platform to be weigh
Wait few seconds for display stable, then press .The value will be
saved and printed (if the printer is connected).
Display will be appear this display will
appear two seconds only.
Remove the load and wait few seconds for display return to zero.
Place the second goods on the platform.
Wait few seconds for display stable. Then press .The value will be
saved.
Followed by the total number of weight will be displayed
It can continue the process until the maximum capacity or value.
Note: When you change the weighing unit this saved values will be clear.
