Current loop calibrators are versatile devices used to simulate the operation of loop powered transmitters, source current to unpowered devices in a loop and measure current. With features such as microprocessor based electronics and digital interfaces, they make excellent troubleshooting tools for circuits. Current loop calibrators are commonly used in areas such as:

• Research and development
• Servicing
• Process control engineering
• Calibration technician

This current loop calibrator with temperature measurement can work with 11 types of thermocouples including K, J, E, T, R, S, N, L, U, B and C.

Determined by Ohm's law, which states that the current between 2 points through a conductor is directly proportionate to the voltage across those 2 points, divided by the resistance of the conductor. I = V/R. This is also the case for series and parallel circuits, however in parallel circuits the total current can be affected by the way the resistors have been connected, as well as their ohmic value. Current does divide up and there can be more current in one area over another nonetheless when all areas are added up the total amount is the same.
