This simple but clever continuity tester sports two LEDs: RED LED = circuit resistance is < approx 10K, GREEN LED = circuit resistance <10Ω. It consumes approx 8mA from a 9V battery. When not ...

One of the core features of the scientific community is the concept of “peer review” where any claims made by a scientist are open to be analyzed and reproduced by others in the community for ...

This simple circuit uses a 741 op-amp in differential mode as a continuity tester. The voltage difference between the non-inverting and inverting inputs is amplified by the full open loop gain of the ...

The Arduwire UNO is an innovative shield designed for the Arduino UNO development board. This shield enables users to perform a variety of tests on cables and harnesses, including continuity, open ...

The VPC-30 voltage and continuity tester features a built-in shaker that provides the same functionality and feel as older analog solenoid testers The VPC-30 voltage and continuity tester features a ...

In addition to basic continuity testing, the Model ST1000 hand-held SCSI cable tester will display the presence or absence of TERMPWR, indicate whether the bus is SE, HVD, or LVD, and display the ...
