ROCHESTER, New York -- AMETEK Power Instruments, the newest business unit of AMETEK, Inc. and a world leader in power measurement, has introduced their new Scientific Columbus JEMStar electricity meter. The new multi-function revenue meter can be summed up in two words: "Simply Powerful". It brings together new technology resulting in a simple user interface with powerful functionality.
As electricity meters have gained more functionality, they also have become more difficult to use. Technicians need to attend specialized training sessions to learn the complicated programming software and meter interface. Without working with the meter regularly, technicians often waste time relearning its functions. Believing there is a better way, AMETEK Power Instruments developed the new JEMStar with the user in mind. Simple to configure and use with very powerful capabilities.
The new JEMStar meter has made complicated metering a thing of the past. Use of the meter was simplified in two ways. First, it utilizes a graphic display that allows it to display data in a simple to navigate menu format via directional keys. This eliminates the need for encrypted warning codes and combinations of buttons to access certain features. Site verification of wiring can be accomplished by viewing an on-screen vector diagram with amplitudes and phase angles displayed. In addition, communications can be tested before leaving the site.
In addition to the local interface, AMETEK made some revolutionary changes in the software. To simplify the learning and use of the programming software, AMETEK added a configuration wizard similar to the chart and presentation wizards that are used in many Windows¿ based applications.
The wizard walks the user through the configuration step by step in a simple progression that builds the meter configuration file. There is a comprehensive help program available to answer users¿ questions. These simple-to-use tools make it easy to build configurations without the need for comprehensive training classes.
Being simple to use does not mean the user has to give up powerful functionality. In an industry, where an error as low as a fraction of a percent can mean the loss of thousands of dollars, the JEMstar meter captures the money lost through inaccurate measurement. With a watt-hour accuracy of 0.07% of reading, the JEMStar delivers performance the user can take to the bank.
The JEMStar meter features include four-quadrant, per phase, and instantaneous measurements; transformer loss compensation; and Load Profile. In addition, the new meter has some very powerful communications capabilities. With de-regulation, more people then ever are looking for the data from the meter.
The JEMStar offers simultaneous communications across multiple ports. The user can choose from RS-232, RS-485, and an internal modem for communication connections. Each channel can be set with a different protocol to allow the meter to address different communications requirements simultaneously. For security, there are four programmable passwords that can be used to control information access.
Simple to use, yet powerful in its capabilities, the JEMStar electricity meter bridges the gap between the high-accuracy, multifunction meters with expensive price tags and more basic meters that merely meet budget constraints. The "Simply Powerful" JEMStar offers the most-cost effective metering solution for the new era of electric power de-regulation.
The Scientific Columbus JEMStar meter is available from Rochester Instruments Systems of AMETEK Power Instruments, a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electric motors.
