Features:
- Simple, fast, one-pushbutton operation.
- Digitally displays an accurate reading in seconds!
- Unaffected by contact resistance, the Stitt Tester measures true resistance to 1/10 Ohm.
- The self-powered and portable unit is handheld and requires no lengthy wire installation.
The Eagle Stitt Tester is a compact, hand-held device used to accurately measure low impedances, such as those found in grounding circuits. The device produces a small, 60 Hertz current which flows in the circuit being tested. The Tester accurately determines the value of this current, as well as the amount of voltage produced by this current, and automatically calculates the impedance of the circuit. The impedance is read directly in Ohms from a large, LED display on the front of the Tester. The Eagle Stitt Tester is accurate to within 0.1 Ohm and will determine the impedance of a circuit between 0.0 and 9.9 Ohms. Since the Tester makes use of a Kelvin measurement method, neither the resistance of the connection points nor the resistances of the current and voltage-carrying wires involved in the measurement have any effect on the accuracy of the resultant impedance measurement. The Tester will display the true impedance of the circuit being tested, ignoring any connection resistance or lead resistance. The Eagle Stitt Tester is also useful for testing circuit breakers, contactors, and relay contact resistance. With the two green alligator clips connected to two separate points on one side of the contact and the red and black clips connected to two separate points on the other side, the contact resistance is determined
