LRS-3101 Series Single-phase watt-hour meter locale Calibrator
I. Applications This meter is designed as a basic measuring instrument for many electricians. It may be carried to the field for verifying quickly and accurately the errors of various inductive type electronic single-phase watt-hour meters of Class 1.0 or less. It is an ideal tool for inspecting any electric theft and solving the electricity utilization disputes.
II. Functions and characteristics * Adopt insulated housing, which is small in size, light, beautiful appearance, firm, and portable; * Adopt advanced measuring chips and advanced sampling technology and algorithm to realize the high-speed and real time measurement, and make itself have super accuracy and strong functions; * Internal board adopting the SMT surface paster, with higher reliability; * Large LED screen with mimic and clear interface; * Special keyboard that is concise and easy to operate; * Equipped with special precise clamp current transformer (clamp meter), which can verify the watt-hour meter quickly and accurately without dismantling the meter, and also equipped with the current input circuit adopting advanced compensation technology, which improves the measuring precision greatly; * Adopt special sucker type optic collector supporting automatic collection of mechanic meter black spot and light-on signals of electronic meter LED, which substitutes the collection of electronic meter pulse by clamping the pulse terminal, so ensure the safety and convenience of operation, and also adopts a special pulse sampling line for collecting electronic meter pulse; * Standard pulse output, and convenient sample submission for verification; * Automatic and manual verification mode that is convenient for field application; * Auxiliary power source adopts the signal voltage without connecting with other power source, so it is convenient for field application; * Voltage output range of 60V~380V, which ensure this meter won¡¯t be burnt out due to wrong clamping of circuits; * Real time measurement of voltage, current, power, phase, power factor, and frequency etc. * RS232 interface, convenient for connecting with the computer, downloading the field data, reading the field verification data and managing the data and assets. * Built-in EEPROM of large capacity, which can store 200 users' field verification data and keep them for 10 years without any loss; * The device has stronger anti-interference performance, and will not be dead and lose recorded data upon the field verification; * The device has perfect dynamic features, and can also correctly measure the changing load (such as micro-wave oven, air conditioner and electric water heater etc).
