Why is there no 4-20 mA DC output current in Thermo Scientific SOLA II Measuring Instruments?
If the Thermo Scientific Measuring Instruments show no 4-20 mA DC output current, the problem might be due to incorrect or damaged wiring. Check the wiring diagrams to ensure the 4-20 mA DC signal is connected to the proper terminals with the correct polarity. Also, check for shorts or opens in the wiring.
Why is the 4-20 mA DC output current inaccurate in Thermo Scientific Measuring Instruments?
If the 4-20 mA DC output current is inaccurate in Thermo Scientific Measuring Instruments, it is possible that there is incorrect or damaged wiring. Check the wiring diagrams to ensure the 4-20 mA DC signal is connected to the proper terminals with the correct polarity. Also, check for shorts or opens in the wiring.
