The portable electrical meter tester of claim 1, wherein the circuitry comprises at least one high impedance element to prevent current flow upon detection of back feed voltage.Ĥ. The portable electrical meter tester of claim 1 further including a processor, where the processor checks the circuitry for back feed voltage to connect the electrical meter tester to the test site only when the circuitry detects no back feed voltage.ģ. Terminals connected to the measurement circuitry that releasably connect the electrical meter tester to the electrical metering device andĬircuitry connected to the terminals to monitor for back feed voltage, where the circuitry electrically isolates the electrical meter tester from the current source and the voltage source of the test site if back feed voltage is detected and connects the electrical meter tester to the test site when no back feed voltage is detected.Ģ. Measurement circuitry to determine the accuracy of the electrical metering device A portable electrical meter tester for testing electrical metering devices at a test site, where the test site includes a current source and/or a voltage source, the electrical metering device being connected with the current source and/or the voltage source of the test site, the portable electrical meter tester comprising: Safety circuit for a detachable connecting cableġ. Method of and arrangement for measuring impedances in measuring circuits having programmed memory Test cart for aircraft control surface measurementsĪrrangements and methods for testing various electronic equipments Integrated certification-calibration system for a testing system having multiple test instruments Programmable electronic display for a chart recorder Method and apparatus for calibrating a digital electric engergy consumption meter Portable computer apparatus with articulating display panel System checking and troubleshooting package for an electronic metering device System having active pull-down circuit and method Trans-Data Thermal Mini Printer captures multiple or individual transactions as furnished by one of two M-2000 meter RS-232 ports.Double relay light switching system for providing daytime running lights for vehiclesĭevice for preventive detection of faults with recognition of the type of load This all-stainless transducer ensures reliability in extreme weather conditions. This product allows the M-2000 meter to be converted from our load beam mechanically controlled weighing system to an air pressure transducer controlled weighing system. Trans-Data On-Board Air Pressure Transducer Reports can also include engine monitoring. Monitor one vehicle or your entire fleet in real time, from any PC, phone, pad or other device with Internet access using a secured password no special software needed! In addition to reporting gross, tare, net of individual pick ups, record the date and time of pick up, customer/account name, address, location (lat, long), distance driven. Combine this with a Trans-Data On-Board Scale and record gross, tare, net of individual pick ups when installed on a Roll-off, Rear Loader or Front Loader (with or without adjustable forks, with or without a Curotto type can). Introducing the Trans-Data Load Tracker a fleet manag ement system for vehicle tracking and reporting. The M-2000 meter has two RS-232 ports for downloading scale data.Īt the heart of this truck weight system are three products. This has allowed us to apply this system to a large range of diversified applications. The Trans-Data On-Board Weight System has been engineered to exacting standards. Trans-Data M-2000 Meter for Trans-Data On-Board Scales & Weight Systems We stand behind our products and will do everything possible to ensure that your scale system has the accuracy, reliability and quality that Trans-Data Weight Systems are known for.
