Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile. Specific types include test prods, oscilloscope probes and current probes. A test probe is often supplied as a test lead, which includes the probe, cable and terminating connector.
Lead frame of a surface-mount technology package. Most kinds of integrated circuit packaging are made by placing a silicon chip on a lead frame, wire bonding the chip to the metal leads of the lead frame, and covering the chip with plastic. The metal leads protruding from the plastic are then either "cut long" and bent to form through-hole pins ...
DSL – digital spectralog (western atlas) DSPT – cross-plots log; DST – drill-stem test; DSTG – DSTG log; DSTL – drill-stem test log; DSTND – dual-space thermal neutron density log; DSTPB – drill-stem test true vertical depth playback log; DSTR – drill-stem test report; DSTRE – drill-stem test report; DSTSM – drill-stem test ...
A logic probe is a low-cost hand-held test probe used for analyzing and troubleshooting the logical states (boolean 0 or 1) of a digital circuit. When many signals need to be observed or recorded simultaneously, a logic analyzer is used instead.
An autoranging digital multimeter can automatically adjust the scaling network so the measurement circuits use the full precision of the A/D converter. In a digital multimeter the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal.
Experts are monitoring increases in COVID-19 cases in the U.S. driven by new, highly infectious variants.So take a moment to make sure you how and when to use at-home COVID tests to help you stay ...
False positive COVID-19 tests—when your result is positive, but you aren’t actually infected with the SARS-CoV-2 virus—are a real, if unlikely, possibility, especially if you don’t perform ...
A solenoid voltmeter with attached test leads; the instrument is more rugged than a D'arsonoval type of meter, but not as precise. A solenoid voltmeter is a specific type of voltmeter electricians use to test electrical power circuits. [1]
