Earth resistance clamp is a breakthrough from traditional tester. Neither the supplementary earth leads nor the break earth equipment is necessary. Ground resistance results can be gotten safe and fast by clamping
You are purchasing a used Fluke 97 Scopemeter. Included with sale are: AC power adapter, test leads, 2 banana jack cables, 2 alligator clips, 2 mini grabbers, and a rubberized case. Any questions, feel free to ask.
This is an operating Navy tube/voltage/capacitor/resistor tester. It is unique in that it serves as a tube tester, a multimeter, and a capacitance tester, all in one unit! I took this out of my lab storage (basement) not remembering how to use it but lucky to have full instructions right on the inside front panel!
Features: Autoranging ground resistance measurements from 0.025Ohm to 1500Ohm with 0.002Ohm resolution True RMS AC Leakage current range of 0.2mA to 30A with 1.000mA resolution Programmable Datalogging with 116 data points Programmable Hi/Lo Alarm 0.9" (23mm) Jaw size for large ground rods From the Manufacturer Clamp-on Ground Resistance tester enables non-contact measurements of ground conductors without the need for auxiliary ground spikes. Measures resistance from 0.03? to 1500?
Up for bid is a used EICO Resistance-Capacitance-Comparator Bridge, Model 950B. The unit looks to be complete and is in nice overall condition. Includes a COPY of the Instruction Manual and Construction Manual, which contain a schematic and parts list and a set of test leads.
This calibrated Stark Model 12-22A Dynamic Mutual Conductance Tube Tester is probably the hardest vacuum tube tester to find. It tests both European and American Vacuum Tubes along with Selenium Rectifiers, Transistors and Diodes. Stark was the Canadian subsiduary of Hickok and made electrically identical tube testers, using the Hickok circuits, but with a somewhat different appearance, and a lot wider range of sockets.
