Calibration Source Checker
The Extech 412440-S is a low cost, pocket-sized Calibration Source Checker for simulating current loops and for providing a quick and easy way for checking calibration of meters or controllers. It sources three current levels (4 mA, 12 mA, and 20 mA). Bright red LEDs indicate simulation output and battery status. An overload indication occurs when a load exceeds 240 ohms. Comes complete with 9 V battery, case, and calibration cable terminated with subminiature and spade lug connector.
