A1A-22B Operation Manual | V24A Connect the load cell/junction box, power supply and the analogue data input devices to the amplifier board as per below schematic diagram. 5. C ALIBRATION The A1A – 22B consists of two calibration set points as zero and span calibration.
Span Calibration Step1: Apply the desired full load onto the scale/platform. Step2: Adjust SPAN potentiometer to an output of 10V or 20mA. Note: Anyload recommends repeating the calibration three times zero and span to ensure the most accurate calibration. 6. O PERATING PRECAUTIONS 6.1 Always keep the enclosure cover closed except for the period of the calibration and...
