The Digital Voltmeter and 4-20mA sensors have an input as analog signal which will be converted to digital using an A/D converter. Normally, the A/D converter is calibrated in production … Read More
I just finished a calibration process, but the reading is still a little bit off. Is there any way to fine tune the reading?
In the calibration process, we set the offset of the reference voltage so that the raw analog read 500 when the input to the RJ45 port is 1.25 volts. However, … Read More
