Low cost Analog Loop Tester is a stabilized precision instrument which generates current in the range 4 to 20 mA, and is intended for testing analog control loops.

• It has been developed as a "2 Wire Transmitter", and is extremely simple to use. A LED lights up proportional to the loop current.
• Operating voltage 15 to 50 VDC stabilized or unstabilized.
• Overvoltage protection, overcurrent protection, and reverse polarity protection. These characteristics protect the analog input which is being tested.
• Allows simulation of the behavior of equipment which is out of range (i.e. values less than 4 mA or greater than 20 mA). Developed by engineers with many years of experience in the field of instrumentation.
• An exceptionally useful tool for the industrial engineer, and for all professionals working with instrumentation.
• It is no larger than a packet of cigarettes, and does not need batteries. Comes with two test tables, and extensive documentation with instructions and examples of use.

> Analog loops

A current loop using 4 to 20 mA is a single value communication line which is generally used in industry to transmit the value of a physical magnitude from one point to two or more points.

4..20 mA Current transmission is used because it is simple and less sensitive to electrical and magnetic noise than voltage transmission.
