Hella Gutmann supports workshops amid EV growth with tools to accurately and safely take high voltage electrical measurements
“Following the recent introduction of the mega macs X and macsRemote diagnostic devices, Hella Gutmann has again proactively addressed the future with the addition of another must have tool,” explains head of Hella Gutmann UK, Neil Hilton.
“As is clear by every measure, high voltage (HV) vehicles are here to stay, so the safe and accurate measurement of their electrical voltage is a necessity for workshops that intend to stay in the game, because they don’t want to be turning away business to the vehicle manufacturers (VMs) franchised dealers or other more future oriented competitors.
“They therefore need a tool to allow them to undertake repairs and diagnosis on these vehicles.
“The Hella Gutmann MT-HV module, was specifically created for work on electric and hybrid vehicles and utilises permanently integrated HV measurement technology.
“However, it also incorporates a slot where the more familiar MT-56 and MT-77 low voltage modules can be inserted, which transforms the MT-HV into a wireless measurement module for both low and high voltage measurements.
“Specially designed for HV measurements, the MT-HV’s cables, which have a thick cross-section that makes them easy to hold while wearing protective gloves, also encompass safety features such as the contact switch that must be held when taking the measurement.
“In addition, if necessary, the measuring tips can also be easily replaced and even be used with VM specific, high voltage adapters.
“As an internal battery provides its power supply, apart from the measuring cables, there is no lead or connection that could be a distraction or safety risk when work is being carried out on HV components, because the MT-HV operates wirelessly, with its control unit communicating with a Hella Gutmann mega macs X, for example, via Bluetooth.
“Just as we have done with the mega macs X, we have also changed the way the software licences for the device can be set and changed to suit the immediate requirements of the workshop.
“For instance, provided that the right accessories are used, such as the appropriate measuring tips and terminals, as well as the correct ampere clamps to match the current, the MT-HV with a low voltage module inserted, can be used with a basic X3/X4 software licence.
“This allows the measurement technology to function as a two channel, digital multimeter and ultra-fast oscilloscope, exclusively for low voltage measurements.
“In addition, in conjunction with a MT-77 it can be connected to LPD kit sensors and is able to perform pressure measurements.”
Operating and adjusting using the tablet of the mega macs X
In the high-voltage range, the mega macs X and MT-HV device combination covers all measuring technology functions required in connection with electric and hybrid vehicles – provided the mega macs X is equipped with the highest SDI software X5 and enabled with the X5 licence:
• High voltage measurements up to 1,000 V
• Insulation resistance measurements with variably adjustable test voltage
• Potential equalisation measurements on HV components
• Resistance measurements (HV service connector)
