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. “0” will be displayed and the counting annunciator will be on. Press [Func] key to return weighing mode. After entering counting mode, “count” will be displayed, press [Accum] twice times to enter counting mode directly, indicator will display according to the result of the sampling last time. (In this process, if the ERR4 appears, it means sampling failed, the indicator will keep the result from the last sampling) 3.6 User’s function setting In weighing mode, keep pressing [F] for 5 seconds more, it will enter operator setting mode (mode P), there are 10 modes from P1 to P10 for option, press [Accum] to choose the mode and press [Tare] to choose the parameter.

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 1st is starting bit, the 10th 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- To guarantee indicator clarity and using life, the indicator shouldn’t be placed directly under sunshine and should be set in the plain space.
- The indicator can’t be placed into the place where the dust pollution and vibration are serious.
- 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. - It is strictly forbidden to clean the case of indicator with intensive solvents (for example: benzene and nitro oils)
- 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.
- 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. - During operation, if trouble occurs, operator must pull off the power supply plug immediay, and user should return this indicator to our company for repair. Non-weighing manufacturer should not repair it, or by yourself, otherwise further destruction may happen.
- The storage is not granted the free repair guarantee, because it is easily exhausted products.
■ In order to prolong using life, please charge the cell fully before using it. If you don’t use the indicator for a long time, you must charge the cell every two month and for eight hours/each charging time. ■ Moving or installation must be carefully taken and must avoid strong vibration, impact and bump in order to protect the storage cell from being damaged. - From invoice date, the indicator has a one-year free repair period. If any non-artificially obstacle about the indicator happens under correct using conditions within this period, the user is allowed to send the product with its guarantee card (of the correct number) back to our corporation for free repair.
