"The METRAHIT H+E CAR is a milli ohmmeter from Gossen Metrawatt.","Features:","Applications:","The new METRA HIT H+E CAR (hybrid & E-CAR) is a measuring instrument for testing the electrical safety of electric and hybrid vehicles. It includes, among others, the following tests and measurements:","The Gossen Metrawatt METRAHIT H+E CAR megatester milli ohmmeter is for service and repair of electric and hybrid vehicles. The METRAHIT H+E CAR milli ohmmeter resistance meter is the modern alternative for the well known TH2 (Thomson) and Wh2 (Wheatstone) measuring bridges. It provides an expanded measuring range, greater accuracy and easier reading. As universal measuring and test instruments, they acquire and record values to an integrated memory module including resistance in the milliohm and micro-ohm ranges, as well as normal multimeter resistance values in the ohm to mega-ohm ranges by feeding a measuring current to the resistor, conductor or contact under test."

特性

• Insulation resistance tester
• Testing with 50 to 500 V for components, cables and conductors, for example in aircraft and in on-board electrical systems
• LCD panel with background illumination
• High contrast, even under adverse ambient light conditions
• Compact and multifunctional
• Can be used advantageously in aircraft cockpits as well as in other constricted spaces, which would otherwise require the use of several individual instruments.
• Mains power or storage battery operation
• Furnished with 3 NiMH storage batteries and a mains power battery charger as standard equipment for optimized instrument availability and low operating costs
• DAkkS calibration certificate as standard feature
• Reduced operating costs for use within ISO 9000 quality systems, documented traceability
• Protection against direct contact during charging and discharging
• Protection against indirect contact during discharging (battery in the vehicle) and charging of the traction battery
• Insulation and dielectric strength (insulation resistance between all electric components of the high voltage system and the vehicle frame)
• Insulation of the battery (insulation resistance between the high voltage battery poles and the metallic tray/vehicle frame)
• Voltage of capacitors
• Protection type of electric equipment
• Testing of charging regulators
• Testing of electric motor (nominal voltage, power, speed)
