METRAHITIM XTRA & METRAHITIM E-DRIVE

Isolation Tester, Milliohmmeter,

TRMS Multimeter, Short-Circuited Coil Tester

600 V CAT IV

1000 V CAT III

Applications

The METRAHIT IM XTRA and the METRAHIT IM E-DRIVE are portable,

extremely rugged multimeters designed for use in the field.

They’re suitable for maintenance, service and diagnosis at electric

machines, drive units and systems, for example in automotive,

energy and automation applications.

METRAHIT IM XTRA and METRAHIT IM E-DRIVE multimeters are all-in-

one instruments: insulation tester, milliohmmeter, short-circuited

coil tester and universal multimeter. They’re ideal for safety testing

and diagnosis at electric and hybrid vehicles, as well as all types

of electric machines.

The METRAHIT IM XTRA and the METRAHIT IM E-DRIVE make it possi-

ble to test coils for short-circuits within an inductance range of

10 H to 50 mH (at 100 Hz) in combination with the optional COIL

Adapter 50mH. This range corresponds to motors in accordance

with DIN standards with power ratings of roughly 15 kVA to

80 MVA. A universal adapter for motors with medium power rat-

ings is in preparation.

Features

Insulation Resistance Measurement with Interference Voltage Detection

Insulation resistance measurement with test voltages of 50 to

1000 V. If interference voltage of greater than 15 V AC or 25 V DC

is detected during insulation measurement, an error message

appears briefly at the display, after which automatic switching to

TRMS

AC+DC

voltage measurement at 1 M takes place.

Polarization Index (PI):

When test voltage is applied, insulation resistance is measured

after one minute and after ten minutes. The polarization index is

the ratio which results from the two measured values. In the case

of electric drive units, a value of at least 2 indicates intact insula-

tion and a value of greater than 4 indicates very good insulation.

Absorption Index (DAR)

Practically speaking, the absorption index test is a quick polariza-

tion index measurement. The ISO values measured after 30 and

60 seconds are used to generate a ratio.
