PROGRAMMING MODEL-MD3
1 ) TWO POINT CALIBRATION
Lower Calibration Point :
•Move the Sensor mechanically to the zero position.
1. Press DOWN button continuously, until the word CALL appears on the screen.
2. Press UP / DOWN to set the value on the screen zero or any value desired.
3. Wait 2 second without pressing any button, the last screen appears.
• After this, the equipment goes back to operation mode.So the Lower Calibration Point was defined..

2. Press UP / DOWN to set a desired value.
3. Wait 2 second without pressing any button, the last screen appears.
• After this, the equipment goes back to operation mode.So the Upper Calibration Point was defined.
2 ) SETTING THE DECIMAL POINT
1. Press UP/DOWN button at the same time and continuously, until the second screen appears.
2. Press UP/DOWN buttons to select the decimal point.
3. Wait 2 second without pressing any button, the last screen appears.
•After this, the equipment goes back to operation mode.So the Decimal Point was defined.
