NOTE: You should be aware that this test will not
help you find a single welded or damaged contact
as there are two contacts in series to create a
power contact.
If the contacts bell out without activation of the
Transmitter, then the contact may be damaged or
welded closed. In such instances you should not
use the ArcSwitch® meter and the ArcSwitch®
meter you should be replaced.
When you are going to use your ArcSwitch® meter,
it is good practice for you to check the contacts
before use, so you know that the ArcSwitch®
meter is functioning correctly and is not
damaged.
Connect your Multimeter up to the ArcSwitch™
and Beep test the contacts to check for contact
operation and welded contacts before use.
