Capable of withstanding DC voltages up to 50V but can be damaged by AC inputs.

The Martindale direct current calibrator is able to sink or source a current up to 20mA. It is intended for process control instrumentation and general purpose signal
injection applications. It has a monitor mode facility incorporated into the design, whereby the current (0mA to 20mA) in the process loop can be monitored and read directly from the digital display. This device is also fully protected against inadvertent misuse. This low-cost unit offers exceptional value for money means of delivering and measuring current ranging between 0mA and 20mA currents. This makes it ideal for cost-effective application in testing, calibrating and troubleshooting in a wide range of process control environments.
