CURRENT AND VOLTAGE CALIBRATION PROCEDURE (continued)
CALIBRATION SET-UP:
1. Load the Power Wave Manager Software into
the computer.
2. Use the Ethernet cable to connect the computer
to the POWER WAVE® C300.
3. Connect a resistive load bank to the output
studs.
4. Energize the POWER WAVE® C300.
5. Launch the Power Wave Manager Utility and
establish communication with the POWER
WAVE® C300 (Refer to the software documen-
tation to determine proper connection)
6. Click on the "Calibration" Icon in the menu. A
screen similar to Figure F.14 should appear
and you are ready to begin the calibration
check.
NOTE: The Calibration Screen may look
slightly different depending on the
Software version.
Calibration can only be done under
"Static Load" conditions. Do not
attempt to calibrate while welding.
NOTE: Incorrect calibration can and will affect
welding performance. It is strongly recom-
mended to record and save a "Snapshot"
of the existing settings before making any
calibration adjustments.
returning to original settings if necessary.
(Refer to the software documentation for
instructions on using the Snapshot fea-
ture).

CALIBRATION PROCEDURE:
1. Once in the "Calibration" screen, make sure
that the machine output is OFF (light is BLACK)
and connect a resistive load bank to the output
studs.
2. Set the load bank for 200 Amps.
3. On the Calibration screen, select the 200 Amps
Current Set Point.
NOTE: If the meters on the load bank are not cer-
tified, connect calibrated and traceable

Section).
The Output Studs of the Machine will be
Electrically "HOT" during Steps 4 through 7
-------------------------------------------------------------------
4. Click on the "Turn Output ON" button.
BLACK light on the screen will flash RED indi-
cating that the weld output is turned ON. See
Figure F.14.
5. Adjust the load bank to 200 Amps at approxi-
mately 24 Volts as read on the external calibrat-
ed meters.
6. Using the "Calibration Adjustment" buttons:
Adjust the current so that the external ammeter
reads 200 Amps +/-2A. Adjust the voltage so
that the "Output Voltage" display window reads
the same as the external voltmeter +/-.25volts.
