2.1 Intended Use / Use for Intended Purpose
The METRAHIT IM XTRA BT is multimeter, milliohmmeter, insula-
tion measuring instrument, coil tester and data logger in one. The
METRAHIT IM E-DRIVE BT is a multimeter, milliohmmeter, insula-
tion measuring instrument, coil tester and data logger for hybrid
and electric drives. The METRAHIT IM TECH BT is multimeter,
milliohmmeter and data logger in one.
All three are portable instruments which can be held in the hand
while performing measurements. They can be used to perform
the measurements described in these operating instructions and
in the quick reference guide.
Performance characteristics of the individual models: see “Over-
view of Included Features” on page 2.
The multimeter is equipped with an automatic socket blocking
mechanism for your safety, and in order to safeguard your instru-
ment. This mechanism is linked to the rotary switch and only
allows access to those jacks which are actually required for the
selected function. It also prevents the user from turning the rotary
switch to impermissible functions after the measurement cables
have already been plugged in.
Safety of the operator, as well as that of the instrument, is only
assured when it’s used for its intended purpose.
