PRECAUTIONS

Place the scale on a flat and stable surface.

Verify that the input voltage and the plug type matches the local AC power supply.

Warm up the scale for 15 minutes before using it for the first time.

Keep the scale away from EMI noise, strong wind and vibration, which might cause incorrect reading.

Avoid sudden temperature changes (suitable operating temperature is between 0~40℃)

Disconnect the power supply when cleaning the scale.

Do not immerse the scale in water or other liquids.

Service should be performed by authorized personnel only.

BEFORE USING THE BALANCE

Unpacking and Checking

Open the package and check the instrument for transport damage. Immediately inform your dealer if you have complaints or if parts are missing. The package should contain:

1. Scale body 2. User manual

3. Weighing pans 4. Adaptor

Installing Components

1. Before using the scale, remove the shipping protection screw (rotate counterclockwise), which located underneath the scale and cork the plug buckle.

Note: the RK-30 model doesn´t include the shipping protection screw.

2. Cover the weighing pans on the scale body properly.

Leveling the Scale

To compensate for small irregularities or inclinations at the location, the scale can be leveled. The scale is equipped with a level indicator at the front panel .Adjust the leveling feet until the air bubble in the indicator is centered as shown.

Note: The scale should be leveled each time once its location is changed.

Basic counting

Entering a Known Unit Weight

1. Under the weighing mode, use the numeric keys together with key to input unit weight value, and then press .

2. Put the items on the weighing pan , the scale starts counting.

Note: Symbol “ ” points at “UW” when entered unit weight is lower than 4/5 of scale division.

Unit weight Memory

1. When there is one unit weight on the screen, and press key.

2. Then enter a number for each unit weight. Use

or key to shift

and or key to modify the value (or via numeric keys).

3. Press key to confirm and save. Press key to return to weighing mode without saving.

Note: the maximum unit weight memory could up to 20pcs (00-19).

Unit weight Calling-out

1. Press key. The window displays as shown on the right

2. Input the number of unit (Press to clear the value in the unit price screen firstly)..weight. Press

or key to shift and or key to modify the value (or

via numeric keys).

3. Press key to confirm called-out weight and return to the weighing mode. Press key to exit and return to weighing mode.

Sample Counting and ACAL

Sample Counting

1. Place samples onto the weighing pan (or into a tared container) and input the quantity with numeric keys, then press key . The unit weight is calculated, with Symbol “ ” pointing at “ACAI”. Note: ）The larger the sample size, the more accurate unit weight. ）Symbol “ ” points at “SMPL” when calculated unit weight is lower than ）4/5 of scale division or the quantity of sample is less than 10 pieces.

2. Remove the samples and put the load on, the scale begins to count.

3. Press key to exit and return to the weighing mode.

ACAI

Automatic Counting Accuracy Improvement (ACAI) results in a more accurate count by increasing the reference weight without the need to count additional parts. A higher reference weight is important when there is a risk of inconsistent piece weights or if the reference weight is close to the minimum. ACAI uses an initial averaging unit weight to count additional pieces that are placed on the scale. After a few seconds, the scale gives a beep as the new higher reference weight is used to recalculate the averaging unit weight. The process can be repeated as long as the additional weight is less than the previous reference weight. Once this limit is exceeded, ACAI is turned off. Manual ACAI closing: ACAI acts automatically after sampling when ACAI indication appears.

Long press key to turn off ACAI when ACAI indication disappears. ACAI re-acts when sampling again.

Accumulation

1. Enter the indicated unit weight, press key and put first piece of load on the weighing pan (or into a tared container). (Refer to 7-4-1 and 7-4-2)

2. Press key , the first accumulation event is displayed momentarily before Symbol “ ” pointing at “M+”. The display reverts to normal weighing mode in a second .Remove the first piece

3. Put the second piece of load on, and then press key to add the second accumulation event into memory. Repeat step 2-3 till accumulation actions are finished.

Note: Maximum is 99 pieces. It is able to calculate the second deal when returning to zero after the first one under the condition of more than (or equal to) 20d with stability. Minus weight and gross weight can’t be accumulated. After resetting the sample value or unit weight, the quantity accumulated will be adjusted automatically according to the new setting value.

Accumulation display

1. Press key

to displays the total accumulation data (weight, quantity

and number of weighments)

2. Press

or key to check the total events and

the first 10 accumulation events in detail.

3. When connecting PC, printer DMP or CK, press to output the events

Note: T XX=total accumulation events） K XX=the single accumulation

Accumulation clear

To clear the total accumulation data or the first 10 accumulation events, press key

or to shift the events and then press key to clear.

Symbol “ ” disappears when the total accumulation data is deleted.

Step 1

Press key while powering on or long press key

in the weighing mode to enter parameter setting. Press

key

or to circle the parameters and select SET08

PERI

）

Step 2

Press to enter the external equipment choosing.

Press key

or to select the type of printers.

Press to start initialization. The window of unit

weight displays the type of printer. And the window of total

amount displays UNSU or init））

Step 3

When UNSUP appears, it means the printer can’t be

initialized. Press key

to return to the printer choosing. It needs to be initialized

when init? appears. Press key to start initialization

or press key to return to the printer choosing without

initialization. It displays ok when initialization is finished

and shows the type of printer after one second. Go further

to other parameter setting or press key

to return to weighing mode.

THE CONTROL FROM PC TO SCALE (OPTIONAL)

Step 1 Connect the indicator and computer.

Step 2

Open the serial port to modify. Input the letters Z, T, C , R

and P in the sending window and press key Send again.

The scale can conduct the responding function. Z= Zero,

T=Tare, R and P=Printer, C=Cancel Tare.

EXPORTING DATA TO PC IN THE FORM OF EXCEL

Introduction

Connect the scale with PC and set the parameter of external device as “EXCEL” on the scale, then you could export the weighing data to PC in the form of EXCEL. With this function, you could record/accumulate/average/ data statistical analysis the testing data, which we could call it as scale-

computer data management function.

Note: pls enable “Use Serial Keys” function in the computer.

Hardware connection and settings

1. Use transmitting serial wire or USB wire to connect scale and pc.

Note: pls install usb driver first, if you use usb wire.

2. Parameter settings in scale:

“PERI” = “EXCEL” (external device)

“BAUD” = “2400”/”4800”/”9600” (baud rate)

“PRT.M”= “KEY”/”STABLE” (printing model)

“PRT.F” = “PRT.F01” (printing format)

Enable the function of “Use Serial Keys” in the computer

Set Windows XP as a example:

1. Press “Start” ->”Run”, and enter “access.cpl” ->”OK”.

2. In the dialog box ”Accessibility Options”, enter General option, choose “Use Serial Keys” and press “Settings”. In the dialog box ”Settings for SerialKeys” , set the corresponding Serial port and Baud rate, which should be same as Baud rate in scale.

3. Test if Serial Keys works well. Open a Text Document, and press the Print buotton on the scale. The Serial Keys works well, if pc exports the weighing data to Text.
