An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...
It merged with Sanwa Denki Manufacturing in 1965 and then became part of the SMC Group. In January 1974, Sanwa entered production and sales of transmitters for radio-controlled models and in December, became a member of the Japan Radio Control Model Industrial Association (JRM). [1] In 1975, Sanwa became a division on its own, with an office in ...
A clamp meter. Any meter will load the circuit under test to some extent. For example, a multimeter using a moving coil movement with full-scale deflection current of 50 microamps (μA), the highest sensitivity commonly available, must draw at least 50 μA from the circuit under test for the meter to reach the top end of its scale. This may ...
Many indicators have a mounting lug with a hole for a bolt as part of the back plate. Alternatively, the device can be held by the cylindrical stem that guides the plunger using a collet or special clamp, which is the method generally used by tools designed to integrate an indicator as a primary component, such as thickness gauges and comparators.
Vagus nerve stimulation therapy improved the symptoms of treatment-resistant depression for nearly 500 participants in a major clinical trial.
The Sanwa Group (三和グループ, Sanwa gurūpu) was a leading Japanese keiretsu, based in Osaka, between World War II and the Japanese asset price bubble in the early 1990s. It remains in existence as a jointly held company called Midori-kai (みどり会). Sanwa Bank was a major financier for the textile industry in the 1950s. After ...
Top: Pipe clamp; Upper row: F-clamp or bar clamp, one-handed bar clamp ("Quick Grip"), wooden handscrew; Lower row: spring clamp, C-clamp (G-clamp ), wooden cam clamp. A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure.
IEC 61107 or currently IEC 62056-21, was an international standard for a computer protocol to read utility meters. It is designed to operate over any media, including the Internet. A meter sends ASCII (in modes A..D) or HDLC (mode E) data to a nearby hand-held unit (HHU) using a serial port.
