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