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

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

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.

In setting 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.
