2 Installation and Calibration

Before choosing a location to set up your balance, observe the following:

---- Set up the balance on a stable, even, non-vibration surface

---- Avoid direct sunlight

---- Avoid great temperature change

---- Avoid strong drafts

The ideal location for weighing is suggested at the corner of a room, a stable, even surface where has no drafts from open windows or air conditions.

6 Installation and Calibration

2.2 Setting up the Balance

2.2.1 Setting up with rounded weighing pan

Place first the pan support, then the weighing pan on the balance. Turn

the weighing pan lightly and make sure it does not touch the outside of the balance and turns smoothly.

2.2.2 Setting up with squared weighing pan

Place the weighing pan on the four pan supports

, make sure the pan is stable and the four pan supports totally hidden under the weighing pan.

2.3 Starting the balance

Insert the plug of the AC adapter

into the jack, and insert the other plug into a wall outlet. Press “on/off” key once. In the next 6 seconds, a self-test is performed. At the end of the self-test, a zero readout is displayed, and that means the balance is ready to operate.

The AC power: ≥20W 220V 50Hz.

    Under very dry conditions, the outside of the balance may have static

electricity.

2.4 Leveling the balance

2.4.1 Leveling of balance with rounded weighing pan

Adjust the two front leveling feet until the bubble points to the middle of the level indicator.

4 Configuring the balance

4.1 Operating the configuring keys

    You can only configure the balance before measurement.

    Turn on the balance. Keep pressing the “tare” key, at the same time, press “on/off” key once, lose the “tare” key after 1-2 seconds.

Page line word


---- Word, line, page numbers are automatically displayed from 0 to a

number.

---- Exit to the last menu by each one press of “tare” key at “0”

readout ( word-line-page-weighing mode)

---- Enter the next menu by each one press of “tare” key at non- zero

readout (page-line-word)

---- Press “tare” key once to confirm a code setting. % is displayed

indicates a certain function is on.



---- All functions are set on when produced. No need to set all the

functions. You can set some of the functions to meet your special

requirements.

1 cs = 1g

    For piece count, press “unit” key once to select reference sample quantity: 10 20 50 100 pcs.

3.3.2 Piece count

  Turn on the balance.

    Place the container on the balance. (quit this step if no container is needed)

    Tare the balance.

    Place 10 20 50 100 sample pieces on the balance. Wait until the display is stabilized.

    Operate according to 3.3.1, select the piece count mode.

3.3.3 weighing in percent

    Turn on the balance.

    Place the container on the balance. (quit this step if no container is needed)

    Tare the balance.

    Place the sample on the balance. Wait until the display is stabilized.

    Operate according to 3.3.1,select the weighing in percent mode.

3.4 Outputting and Printing the Data

   Press “print” key, the data will be output through the RS232C plug-in.

   See details in chapter 4.

2.4.2 Leveling of balance with squared weighing pan

    First turn the two back leveling feet counter clockwise until they leave the weighing surface.

    Then adjust the two front leveling feet until the bubble points to the middle of the level indicator.

    At last, turn the two back leveling feet clockwise until they just touch the weighing surface.

2.5 Calibrating the Balance

    For basic weighing, the balance must warm up for at least 5 minutes; For accurate weighing, the balance must warm up for at least 30 minutes.

    You must re-calibrate the balance each time after you set it up in a different area or when ambient conditions change, especially the temperature.

2.5.1 Necessary situations to calibrate the balance :

    ---- Before the first measurement

    ---- After weighing for a period

    ---- Weighing location changed

---- The ambient temperature changed greatly

    Unload the balance, press “tare” key when the display is stabilized. Then keep pressing on the “calibration” key for a while until the calibration weight is displayed and blinking, center the calibration weight on the weighing pan. After the display has stabilized, the deviation of the current readout from the target weight (in grams only) is indicated. Remove the calibration weight.

2.6 Inserting the rechargeable / non-rechargeable batteries

    Stand the balance and insert the 9V batteries in the compartment. Make sure to connect the positive and negative poles correctly.

3 Operating the balance

3.1 Simple weighing

    Turn on the balance. Self-test is performed.

    Tare the balance.

    Place the sample on the weighing pan after “zero” is readout.

After the display is stabilized, read the results.

3.2 Weighing using containers

    Turn on the balance. Self-test is performed.

    Place the container on the weighing pan.

    Tare the balance.

    Put in the sample. After the display is stabilized, read the results.

3.3 Weighing Mode Shifting

3.3.1 weighing mode selecting

    Press “mode” key once. The balance can shift between basic weighing, piece count, and weighing in percent.

The available basic weight units are: g oz ct p kg and cs. Press “unit” key once to toggle between units.

1 oz = 31.1034768g

1 ct = 0.2g

1 p = 453.592375g

1 kg = 1000g
