5.2 Entering Breaker Name
The MTK2000 is capable of storing test results as each test is per-
formed. For this reason, it is important to label the breakers subject
to test in the MTK2000 memory. When prompted for breaker name
on the display screen press Start then use the Up Arrow and Down
Arrow to change the character and Start button to advance to the
next character. The Cancel button can be pressed to move to the
previous field. The Phase Select button, when pressed, performs
the delete function. Once the entry is complete, press the Test
Select button to proceed.
It is important to press the Cancel button twice to return to the
Home Screen after performing all tests on one breaker before pro-
ceeding to the next breaker so that a new breaker name can be
entered.
