User Manual
Note: The Fluke 8506A Digital Multimeter must be used for the following calibration. The
8506A must be set to the AC HI ACCUR mode for all AC measurements.
AC Volt Full-scale:
Program the output to the 300 volt range. Close the output relay. Program the output to 240 volts
and 60 Hz. Go to the MEASUREMENT CALIBRATION screen. Enter the actual AC output
voltage for the VOLT FS parameter and press the ENTER key.
AC Current Full-scale:
Apply a load to the output. Refer to Table 6-2. Program the output to 150 volts on the 150 volt
range and 60 Hz. Observe the actual output current and enter this value for the CURR FS
parameter. Press the ENTER key.
For the following calibration steps put the external Digital Multimeter into the DC mode.
DC Volt Zero:
Go to the PROGRAM 2 screen and program the DC mode. Go the PROGRAM screen and
program the 300 range and +2.0 volts. Go to the MEASUREMENT CALIBRATION screen and
enter the value displayed on the external meter for the VOLT ZERO parameter.
DC Volt +Full-scale:
Program the output to +240 volts. Go to the MEASUREMENT CALIBRATION screen. Enter the
actual DC output voltage displayed on the external multimeter for the VOLT FS parameter and
press the ENTER key.
DC Current Zero:
Program the 150 volt range and 0 volts. Apply a 67 ohm, 270 watt load to the output. This
resistor will represent approximately a 2 amp load. Program the output to 135 volts. Enter the
actual DC load current for the CURR ZERO parameter in the MEASUREMENT CALIBRATION
screen and press the ENTER key. If this adjustment can‟t be successfully made, perform the
Current Monitor Offset Adjustment in paragraph 6.6.
DC Current Full-scale:
Program the output to 0 volts on the 150 range. Apply load resistor to the output. Refer to Table
5. Program 135 volts. Enter the actual output current for the CURR FS parameter in the
MEASUREMENT CALIBRATION screen. The value indicated by the External DVM is called V
or V . The current measured by the current shunt is called I

For a multi-phase power system that uses one controller, 15003iX, repeat paragraph 6.5 for each
phase. Move the external test equipment to the phase that is being calibrated. Refer to Figure
6-2.
While viewing the calibration screen, press the PHASE key to select the respective phase.
