remote disconnection of power and improved monitoring of power outages to assist maintenance crews in reducing restoration times. The first four digits of the serial number for this type of meter start with 0530xxxxxx. This meter has a liquid crystal display (LCD) to show the electricity consumption that is being recorded. It is also capable of storing interval data (load profile) that can be downloaded. The meter is programmable for time-of-use (TOU) metering‚ and is capable of bi-directional

Monitor (computer)‚ in computer science‚ device connected to a computer that displays information on a screen. Modern computer monitors can display a wide variety of information‚ including text‚ icons (pictures representing commands)‚ photographs‚ computer rendered graphics‚ video‚ and animation. Most computer monitors use a cathode-ray tube (CRT) as the display device. A CRT is a glass tube that is narrow at one end and opens to a flat screen at the other end. The CRTs used for monitors have rectangular

Purpose: To determine the reaction order with respect to crystal violet dye. Procedure: Turn on a Spectronic 20 and warm it up for at least 15 minutes. Be sure the wavelength is set to 540nm. When the instrument has warmed up‚ use a clean small test tube from the drawer filled 2/3 with the first NaOH solution that is planned to use‚ as a blank set 0% and 100% transmittance. Take a %T reading every minute for at least 15 minutes so it may be convenient to wait until the room clock’s second

99 000 RPM Contact-Less Digital Tachometer Featuring LCD display and automatic DATA hold function By Ibrahim Kamal Last update: 14/7/10 This article describes how to build a contact -less tachometer (device used to count the revolutions per minute of a rotating shaft) using a 8051 microcontroller and a proximity sensor. As the name implies‚ what makes this device special‚ is that it can very accurately measure the rotational speed of a shaft without even touching it. This is very interesting

Case Summary –Chi Mei Optoelectronics 1. What prompted CMO to diversify from its core petrochemical base? What were the risks involved? In the late 1980s‚ Ho started to think that the future for petrochemicals in Taiwan was not very bright. At that time‚ he made the first visit to the nascent Hsinchu Science-Based Park where he found that everybody was doing pretty well. Then he began to think diversifying into something. Ho’s good friend Wu had been the principal investigator on the first TFT-LCD
