Hibar Systems Ltd was a Canadian manufacturer of automated, precision liquid dispensing and filling systems. Hibar was started in 1974 when German-born Canadian engineer Heinz Barall developed a prototype of a precision metering pump that would dispense a small, precise amount (two microlitres ) of electrolytes into button cell batteries.
Leakage tester: Measures leakage across the plates of a capacitor LCR meter: Measures the inductance, capacitance and resistance of a component Megger tester: Measures Resistance of an Winding of Motor or Generator And Measures Earthing's Resistance Microwave power meter: Measures power at microwave frequencies Multimeter
The Keithley 236 introduced in 1989 was the first stand-alone SMU and allowed system builders to integrate one or more SMUs with a separate PC control. Over time stand-alone SMUs have evolved to offer a broader range of current, voltage, power level and price points for applications beyond semiconductor characterization.
Inexpensive analog meters may have only a single resistance scale, seriously restricting the range of precise measurements. Typically, an analog meter will have a panel adjustment to set the zero-ohms calibration of the meter, to compensate for the varying voltage of the meter battery, and the resistance of the meter's test leads.
The Creative Electronics ESR meter was the primary device many used for the duration of the patent. The patent expired in 1998 when many other companies entered the market. Additional patents extended the original work, including John G. Bachman's 2001 "US Patent #6677764: System for protecting electronic test equipment from charged capacitors ...
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
Possibly the best known multimeter of the range was the Model 8, which was produced in various versions from May 1951 until 2008; the last version was the Mark 7. The multimeter is often called simply an AVO, because the company logo carries the first letters of 'amps', 'volts' and 'ohms'. The design concept is due to the Post Office engineer ...
Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
