Section 3: MTK2000 Setup
3.1 General Information
Place the MTK2000 on a stable surface prior to testing . The handle
can be rotated for ease of viewing and operation by pressing the
buttons on the sides of the handle and rotating the handle to the
desired angle (see Flowchart at back of document) . When power-
ing on, the MTK2000 will run a self diagnosis before displaying the
Home Screen (see Flowchart at back of document) .
3.2 Hardware Connections
Insert the power supply into a standard 120V outlet and plug the
opposite end into the MTK2000 . Plug the breaker cable into the
MTK2000 and insert the grooved end into the breaker trip unit .
Check the long time memory jumper position before plugging con-
nector into test port .
3.3 Storing Test Results
The MTK2000 is capable of storing data obtained from multiple
tests on the included SD Card . These results can be downloaded
to a computer via the communication cable included in the kit or
by importing the data directly from the SD Card . This data is saved
automatically to the MTK2000 as each test is performed . Once the
memory is full, the MTK2000 automatically begins to write over the
first test in memory . Because calibration data is also stored on the
card, it is crucial to the operation of the MTK2000 that the informa-
tion on the SD Card is never removed .
It is important to press the
Cancel
button twice after performing all
tests on one trip unit before proceeding to the next trip unit so that
a new breaker name can be entered .
3.4 Powering Up the MTK2000
Press
Power
on the MTK2000 . Once the kit powers on, the self-
diagnosis has been completed and the kit is ready to test the trip
unit . Upon power up and following self-diagnosis, the MTK2000 will
display the Home Screen . Press
Test Select
.
3.5 Setting the Date & Time
Reference
Flow Chart for this section in order to understand how
to modify the System Setting for the MTK2000, press the
Down
Arrow
immediately after the MTK2000 displays the Home Screen .
The Home Screen will read “System Settings –> Date & Time” .
Press
Start
to modify the date . Use the
Up Arrow
and
Down
Arrow
to modify values in each selection and press
Test Select
to
proceed . Once completed press
Cancel
to return to the Systems
Configuration menu . Pressing
Cancel
once more will return the
MTK2000 to the Home Screen .
3.6 Communication Settings
Reference
Flow Chart for this section in order to understand how
to modify the System Setting for the MTK2000, press the
Down
Arrow
immediately after the MTK2000 displays the Home Screen .
Once “System Settings –> Date & Time” is displayed, press the
Down Arrow
to verify “Communications” is displayed .
Press
Start
to modify these settings . Use the
Up Arrow
and
Down
Arrow
to modify values in each selection and press

Cancel
to return to the Systems
Configuration menu . Pressing
Cancel
once more will return the
MTK2000 to the Home Screen .

4.2 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 .
