Chapter 3 Operation

3.1 power on and auto zero-setting

3.1.1 The indicator will perform “999999-000000” to self-checking when turning on. Then it will enter weighing mode.

3.1.2 When power on, if loading weight on the scale deviates from the zero point, but still within zero set range, the indicator will set zero automatically; if out of range, it is necessary to adjust the zero point or recalibrate or reset.

3.2 Manual zero setting (Automatically)

3.2.1 In weighing mode, when there is some error when unloaded, press [Zero] to make the indicator to be zero.

3.2.2 If the displayed value deviates from zero point, but still within zero-range, pressing [Zero] key is available. Otherwise, [Zero] key is invalid. (In this status, please recalibrate or reset zero parameters)

3.2.3 Only when stable annunciator is on, zero operation can be available。

3.3 Tare function

When Indicator at weighing status, and displaying positive weight stable, press [ Tare ] key, indicator will deduct the displayed weight value as tare weight. Then indicator displays net weight as “0 ”, and Tare sign annunciator is on.

3.4 Accumulating function

In weighing mode, when the displayed value is positive and stable as well, press [Accum] key to

accumulate the present weight and display the accumulated weight, the accumulate annunciator will

be on. Press this key again, it will back to weighing mode and the accumulate annunciator will be off.

The next accumulating operation must be performed after the weight return to be zero. When the

accumulated weight displayed, press [Func] key to clean the accumulated weight in Memory and

press [Accum] to return weighing mode. If the accumulated weight needs to be checked, please keep

the load of platform to be zero, then press [Accum] to display the accumulated weight.

3.5 Counting function

In weighing mode, press [Func] to enter the counting state, it will display “count”, and press [Accum]

it will display “C00000”, then press [Tare] to move the digit corresponding with the small triangle, the

number corresponding with the small triangle will be increased one by one each time after pressing

[Zero] key; and it will enter counting function after the sample number inputted and [Accum] pressed.

3.7 Connect scoreboard to indicator (function optional)

3.7.1. Electric current or RS232 interface is used for scoreboard signal, which is transmitted in

serial binary code style. The baud rate is 600.。

■ Make sure that scoreboard and output lead are connected correctly. If there is something wrong with connection, damage will happen to output port of instrument and input port of scoreboard, sometimes, the damage is so big to influence the instrument and scoreboard. Only specially provided connecting cable is allowed to be used.

3.8 Serial communication and indicator connection

■  Make sure that communication interface output lead and computer are correctly connected, if there is something wrong with connection, damage will happen to output port of instrument and input port of computer, sometimes, the damage is so big that instrument, computer and corresponding peripherals are got involved.

■ Necessary computer technology and programming expertise are required for computer communication, which should be participated and instructed by professionals. Non-professional staff is supposed not to be involved in this regard.

With RS232(optional) serial communication interface, the XK3190-A12 indicator can be connected to

computer for communication.

1.   All data are ASCII code, every set of which is composed of 10 bits: the 1^st is starting bit, the 10^th is stop bit, the middle in between are 8 data bits.

Communication mode as follows:

(1). In continuous mode:

       The data transmitted is weight (Gross weight or net weight)

       The format of G.W.：ww000.000kg or ww000.000lb

       The format of N.W： wn000.000kg or wn000.000lb

       Note：The position of above decimal is decided by the decimal set on the indicator.

(2). In command mode:

The indicator performs the corresponding operation according to the command transmitted from the indicator.

Command R The indicator receives and sends weight data once time (the format is the same as the continuous mode)

Command T The indicator receive the command and tare (the same as tare key); if no receipt of the command. The indicator returns CR LF

Command Z The indicator receives the command and zero (the same as zero key); if no receipt of the command, the indicator returns CR LF.

Chapter 6 Chargeable Battery

6.1 Turing on the AC power, the indicator will charge the battery automatically. So if you don’t use battery frequently, you should take battery out.

■ Note: red end is +, black end is -. Wrong connection will destroy indicator.

■ Note: The built-in battery should be fully charged before it is used for the first time.

6.2 Only when you turn off the AC power, and push start key, battery works. Displaying [LouoL] means the insufficient of voltage, it needs charge.

6.3 When you use the battery first time, you should charge the battery for 20 hours in order to prevent low voltage resulted from the self leakage of the battery.

6.4 If you don’t use battery for a long time, you should charge the battery for 10-12 hours for each 2 month to prolong using life of battery.

6.5 The battery is easily exhausted products. And it is not granted free guarantee.

Chapter 7 Maintenance

1. To guarantee indicator clarity and using life, the indicator shouldn’t be placed directly under sunshine and should be set in the plain space.
2. The indicator can’t be placed into the place where the dust pollution and vibration are serious.
3. Load cell should connect with indicator reliably, and the system should be well connected into ground. The indicator must be protected from high electrical field and high magnetic field.

  ■ In order to protect the operator, indicator and relevant device, you should mount lightning rod in thunderstorm frequently happening area.

  ■ Load cell and indicator are static sensitive device, you must adopt anti static measures.

1. It is strictly forbidden to clean the case of indicator with intensive solvents (for example: benzene and nitro oils)
2. Liquid and conducting particle should not be poured into the indicator, otherwise the electronic components will be damaged and electric shock is likely to happen.
3. You should cut off power supply of indicator and relevant device before you pull-in and out the connecting line of indicator and external device.

■You must cut off power supply of indicator, before pulling out connecting line of load cell.
