2. INTRODUCTION
The RWP series weighing indicator 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 scale, 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.
1. Indicator
2. Adaptor
3. Manual
4. Indicator holder (Optional)
5. Load cell Output connecter (Optional)
6. RS-232 Output Connecter (Optional)
Installation
Place the Indicator 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 indicator.
Connect the adaptor pin in to the indicator adaptor jack.
Adaptor jack is locating, back side of the indicator.
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
Load cell connections
Connect the load cell cables to the terminal as shown below.
It can connect four 350 ohm load cells.
The load cell drive voltage is 5V DC ±5% between
Excitation + and Excitation -.
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

.
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.

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.
