AC Volt Full-scale: Program the output to the 300 VAC range. Close the output
relay. Program the output to 240 VAC 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. Save this value by pressing the SET key.
Note: This process may take as long as a few minutes to
complete after the enter key is pressed.
AC Current Full-scale: Apply a load to the output. Refer to Table 6-1. Program the
output to 120 VAC on the 150 VAC range and 60 Hz.
Observe the actual output current and enter this value for the
CURR FS parameter. Press the ENTER key. Save this value
by pressing the SET key.
DC Volt Full-scale: Program the output to the 400 VDC range. Close the output
relay. Program the output to 320 VDC. Go to the
MEASUREMENT CALIBRATION screen. Enter the actual AC
output voltage for the VOLT FS parameter and press the
ENTER key. Save this value by pressing the SET key.
Note: This process may take as long as a few minutes to
complete after the enter key is pressed.
DC Current Full-scale: Apply a load to the output. Refer to Table 6-1. Program the
output to 160 VDC on the 200 VDC range.
Observe the actual output current and enter this value for the
CURR FS parameter. Press the ENTER key. Save this value
by pressing the SET key.
