2.2 KEY FUNCTIONS
[FUNC ] Keep pressing this button for 5 seconds more in weighing mode, it will come into
operator setting mode; less than 5 seconds, it will come into counting mode.
[ACCUM ] Press this button to accumulating the weight in weighing mode.
Press this button for sample taking in counting mode
[TARE ] Press this button to tare in weighing mode.
[ZERO ] Press this button to zero in weighing mode.
[ON/OFF ] Press this button to start the indicator when it is off; and press it to shut off upon on.
2.3 CONNECTING LOAD CELL TO INDICATOR
1. The 9-pin socket is used for the link-up of load cell, which has been clearly shown in the graph
2-3.
2. The 4-pin shielded cable is used, and the indicator does not have the function of long distance
compensation.
■3. Indicator must be reliably connected to Load cell and shielded-cable of load cell must be
reliably connect ed to underground. If indicator is powered on, the user should not insert or
withdraw the plug in order to protect the indicator and load cell.
■4. Sensor and indicator are static sensitive devices; you must adopt anti-static measures. The
electric wielding operation and other strong electric operation are prohibited. In order to protect
the operator, indicator, and relevant devices, you should install lightning rod in the
thunderstorm frequently happening area

Chapter3Operation
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.
“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)

3.7 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 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.

Zero point calibration:
Press [#] when the stable
signal is on
[nOLOAD] Assure there is no load
5
Full range point calibration:
Press [#] when the value
input is the same as the
loaded weight and the
stable signal is on [AdLOAD]
While inputting the loaded weight,
Press [TARE] for selection of the digit bit; Press
[ZERO] for selection of the digit; when the input
value is the same as the loaded weight and the
digit bit is at the highest bit, press [#] when the
stable signal is on
6 [ End]
7
Press the calibration
switch under the lead
sealing board at the back
of the indicator
It saves the calibration parameter and back to
the weighing status. Attention: if no pressing the
calibration switch, all the parameters won’t be
saved.
4.2FAST CALIBRATION FOR ZERO POINT AND FULL RANGE POINT
Press [#] while it is initialization, it enters into the calibration mode.
4.2.1 Fast calibration for zero point:
At any time before it shows [nOLOAD], press [FUNC], it keeps the original division, decimal point, full
range and enter into the zero point calibration mode. Press [ZERO] when the stable signal is on, it
displays [End] and keeps the original full range point calibration. Press the calibration switch under
