How do I determine what calibration weight to use if it needs to be 10% of full scale?
In order to take advantage of the push-button calibration feature on the A4 Digital Amplifier, the calibration weight used must be equal to 10% of the load rating of one of the load cells. For instance, if the load cells are rated for 250-lbs, then a weight of 10% of this value should be used (25-lbs). A weight other than 10% of the load cell load rating can be used, however the calibration procedure must be performed utilizing a laptop computer, a USB cable, and the free calibration utility available on the A$ Product Page
Once this program is downloaded and installed on your laptop, the amplifier can be calibrated utilizing any known weight that is at least 10% of the stated load capacity of the load cells.
