Definition
Underwriters Laboratories, Inc. is an independent laboratory that establishes standards for commercial
and industrial products.
an external peripheral interface standard for communication between a computer and external
peripherals over a cable using bi-serial transmission. It supports both isochronous and asynchronous
data transfers.
the maximum value that can be measured by a transmitter within the stated accuracy
the highest measured value to which the transmitter is calibrated

volts of direct current
a storage medium that loses all data when power is removed
the unit of voltage or potential difference. One thousand volts = 1kV.
electrical pressure, the force, which causes current to flow through a conductor. Voltage must be
expressed as a difference of potential between two points since it is a relational term. Connecting both
voltmeter leads to the same point will show no voltage present although the voltage between that point
and ground may be hundreds or thousands of volts.
a meter for reading voltage. Reading voltage is one of several functions of a multimeter.
