There are 2 rows of 6 LED's corresponding to each of the possible connector pins and one for the screen (or ground) connection. As each pin is activated, the LED's indicate all connections associated with that pin, so that short, open and crossed circuits can be easily found. The LED's also show the possibility of high resistance or leakage connections.

WL MIDGET -
Walter G. Legge Company Inc.
WL MIDGET Surface Resistance Meter is an ultra-wide range, battery operated, portable instrument for measuring Surface Resistivity and Resistance to Ground of virtually any flat surface conforming to ASTM D-257 standard method by using recommended parallel bar sensing probe. Gives simple, repeatable measurements of conductive, static dissipative, and insulative surfaces. Ranging is automatic due to the use of high-speed OP-AMP Integrated circuits being linear, with changeover points +1/2 decade on a logarithmic scale. Repeatability equals + 5%.

NGR Sensing Resistors are attached in parallel to the neutral grounding resistor. The sensing resistor allows a protective relay to detect a resistor failure in a continuous manner. Sensing Resistors are used in combination with neutral grounding resistor monitor relays. The relay measures neutral grounding resistance, neutral grounding resistor current and neutral to ground voltage. The relay continuously measures neutral grounding resistor ohmic value in an unfaulted system and it trips on if neutral grounding resistance varies from its calibrated value.

RMO-M Series -
IBEKO Power AB
The motor/generator winding resistance test is used to identify open windings, shorts between two windings, short to grounds, connection mistakes or shorted turns. This non-invasive test of winding resistance helps to pinpoint problems regarding windings in stator or rotor part of an electrical machine. Additionally, motor winding ohmmeter has the capability of performing heat run test which will show a change in windings resistance with an increase of temperature.The RMO-M series is designed as an ideal aid in preventive maintenance of electrical motors and generators. They are powerful (up to 100A of test current), portable (8 kg) and generate DC current which is completely ripple-free. This makes measurement very precise with 0,1% accuracy.Three voltage channels make measurement very easy since it is possible to obtain a value of all three winding resistances in one measurement

WT 25-4145.26M -
Walter G. Legge Company Inc.
WT 25-4145.26M Wristat Tester is available to comply with D.O.D. 4145.26 specifications. The WT25-4145.26M Wristat Tester is designed to test the integrity of our WRISTAT in a fast, efficient, and simple manner. All the elements of the WRISTAT – continuity of the strap, integrity of the protective resistor, and satisfactory strap to skin contact – are easily confirmed by pressing the top cover of the WT25-4145.26M. The operator (wearer) is tested for a resistance to ground of greater than 250K ohms and less than1,200,000 ohms. The upper limit notifies you of an unacceptably high resistance value (IE possible loss of effective dissipation) and the lower limit warns of unsafe low resistance (possible risk of electric shock from surrounding motors, live wires etc.). The unit is not switchable.

HRG systems limit the fault current by placing high resistance between neutral point of transformer (or generator) and ground. As it is not possible to locate the fault point in delta connected systems, an artificial neutral point is created and delta connected system can be grounded. This allows a fault current of a few amperes thus locating the fault point gets easy. When the neutral point is grounded thru high resistance, both continuity of operation is provided during fault condition and sufficient current (typically between 2 A and 10 A) flow is provided for ease of locating the fault point.
