For example, the *CAL? command runs a self-calibration routine on some equipment, and then returns the results of the calibration. Similar commands are grouped into a hierarchy or "tree" structure. [3] For example, any instruction to read a measurement from an instrument will begin with "MEASure".
Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .
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 formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
If the micrometer measures 0.7503 inch, then it is out of calibration. Cleanliness and low (but consistent) torque are especially important when calibrating—each tenth (that is, ten-thousandth of an inch), or hundredth of a millimetre, "counts"; each is important.
Some manufacturers include a continuity test lamp function in a solenoid meter; these use the same probes as the voltage test function. This feature is useful when testing the status of contacts in energized circuits. The continuity light displays if the contact is closed, and the solenoid voltmeter shows voltage presence if open (and energized).
I and V sweeping—Sweep capabilities offer a way to test devices under a range of conditions with different source, delay and measure characteristics. These can include fixed level, linear/log and pulsed sweeps. On-board processor—Some SMUs further improve instrument integration, communication and test time by adding an on-board script ...
