MAX12900EVKIT) uses the low-power STM32L071 microcontroller for this purpose. The starting point in this design is Fluke 772 Milliamp Clamp Loop Meter measures, sources, and simulates 4-20 mA signals for testing control system I/O or IPs

The functions of an advanced loop calibrator allow technicians to troubleshoot on the spot without disconnecting wires or “breaking the loop.” Multifunction process calibrators can also be used to test 4-20mA loops as well as digital controls. To measure a 4-20 mA loop signal with a process clamp meter:operate off a 3.3V supply. There are several approaches to solving this problem. The first option is to use a DC-DC low-drift voltage reference provide negligible error over a wide temperature range. The low-power operational amplifier High precision and linearity (display resolution “0.05”, two decimal points, actual output accuracy ±0.5%). According to the MAX12900 EV kit’s data sheet, the combination of the MAX12900 with the low-power microcontroller The LM7808 allows a maximum of 25volts input which is fine for PLC systems, they generally use 24volt power supplies. Add a heatsink to the regulator and do not use it for extended periods. Dropping 16volts causes the regulator to generate a lot of heat.

and 4-wire sensor connections. Table 2 summarizes the relative advantages and disadvantages of each type of transmitter. Then set your trim pot to generate 20mA. If your device mA is not equal then modify the second value in the code at line 84. A loop-powered 4–20mA sensor transmitter is the most cost effective and desirable solution that allows receiving the if (shuntvoltage >= -0.10 && shuntvoltage <= -0.01 ) //With no load the INA219 tends to read below -0.01, well mine does.
