responsibility of the user
Only qualified and trained operators should operate the MTO system. Operator
must read and understand this entire Instruction Manual prior to operating the
equipment. Operator must follow the instructions of this Instruction Manual and
attend the equipment while the equipment is in use. In the event of equipment
malfunction, the unit should immediately be de-energized and returned to
Megger for repair.
“The Safety precautions herein are not intended to replace your Company’s
Safety Procedures. Refer to e.g. IEEE 62-1995/IEEE C57.152 and IEEE 510 -
1983, IEEE Recommended Practices for Safety in High-Voltage and High-
Power Testing, for additional information.”

WARNING
When applying current to a transformer with very high
inductance, additional care should be taken not to remove current
or voltage leads while current is still flowing. This causes an
extremely high voltage to develop across the point where current
is broken. Under certain conditions, this voltage could prove to
be lethal.
The Megger Transformer Ohmmeter has built-in safety protection thru the
VOLTAGE POTENTIAL LEADS. Voltage leads shall always be connected in
parallel with the current leads.
Example: If a current lead is disconnected while current is flowing through the
transformer, the current will flow through the alternate path of the
potential lead without damage to instrument or electrical shock to
operator.

WARNING
It is very important not to connect any leads on top of or too close
to one another. Take the necessary precautions to assure one
lead falling off will not take a second lead with it.
