ntroduction
2.1 General
The MOM2 is designed to measure the resistance of
circuit breaker contacts, bus-bar joints, contact ele-
ments in bus-bars and other high-current links.
When contact resistance rises because of oxidation,
loosened or improperly tightened threaded joints,
temperatures rise abnormally at the points of contact.
This abnormal heating reduces conductivity thereby
accelerating the rise in temperature — and this often
leads to serious trouble.
The MOM2 micro-ohmmeter can be used to detect
such problems early so that they can be remedied
long before trouble starts. Checking contact resistance
at regular intervals provides a clear indication of the
state of your system.
Unpack system
Unpack the unit and check for evidence of any ship-
ping damage. If there is any visual damage, imme-
diately notify the freight carrier to make a damage
claim, and notify Megger of the damage.
2.2 Service and support
For technical assistance please contact your local
representative or direct your request to Megger in
Sweden.
When sending the instrument, please use either the
original crate or one of equivalent strength.
Add the return authorization number to the address
label of the shipping container for proper identifica-
tion and quicker handling.
