2. INTRODUCTION
The MI104 Compact weighing indicator amplifies the signals from load
cell(s), converts it to digital display as a mass/ force value.
It is suitable for general weighing or more specialized applications such as
check weighing, animal weighing and accumulation applications.
MI104 Indicator can be connected to a Serial printer or a PC.
MI104 has a large (22mm high) LCD with white LED back light display

Turn on the On/Off key. If you want to turn off, press the key again.
Display will show the software version number and will start self-checking.
After self-checking, display will come to normal weighing mode.
Warm-up time of 15 minutes is recommended for stabilization after
switching on.
Calibrate with accurate calibration weights, minimum 1/3 of the scale
capacity is recommended for calibration.
For calibration see details in Section 6- Parameter.
Load cell connections
Connect load cell cables to the terminal as shown below.
MI104 can connect upto four 350 ohm load cells/ eight 700 ohm load cells.
The load cell excitation voltage is 5V DC ±5% between Excitation + and
Excitation -.
Connect Adaptor and Charging
To charge the battery insert the power adaptor pin to jack. Plug the Adaptor
into the mains power. The indicator does not need to be turned on.
The battery should be charged 6 hours for full capacity.
The symbol status of the battery
Battery voltage is very low

.
Do not use any other type of power adaptor , except the one supplied with
the scale.
Verify that the AC power socket outlet is properly protected.
Note: Please charge the battery fully before using the scale for the first
time.

After the calibration , the display will start a self test. Remove the load from scale
during the self test. Display will come to weighing mode automatically.
If display shows error or incorrect value, repeat the procedure again.
Linear Calibration
The linearity error caused by the performance of the weighing unit can be
corrected by “Linearity Calibration”. The digital linearization function can reduce
the linearity error. MI104 employs a 3-point linearisation.
Precise weight (1/3rd, 2/3rd and full capacity ) are needed for Linear
calibration.
