Features include:

Direct digital reading saves time, no manual balancing is required.

Built-in discharge circuit safely discharges the specimen when test is
completed , if lead accidentally disconnects, or if power is lost.

Test indicator light gives a visual indication of either a charged or discharged
specimen, even if power to the instrument is lost.
 Two independent measuring channels allow simultaneous testing of primary
and secondary windings or measurement of two phases at a time.
 The sensitive tap-changer test circuitry monitors the contact operation of on-
load tap-changers for their correct make-before-break sequence. If an open
circuit condition exists, the instrument shuts down immediately.

Electronically generated and patented regulated current supply overcomes
high-inductance transformers quickly, allowing fast measurements to be
taken.
Display of measurement occurs only after test current stabilizes.
 Wide resistance range is suitable for testing a wide variety of transformers.

Current ramp-up mode continuously tests input compliance voltage and sets
the maximum current based on the specific test load.
 Lightweight and portable, the MTO is ideal for use in workshop or
substation environments.

Over temperature protection provides automatic current shutdown and
indication to prevent instrument damage.

Meets the requirements of both the European EMC and Low Voltage
Directives.
It is recommended that the user becomes familiar with the MTO before making
any connection to a transformer.
