Configuring toroid settings for RCM using the display

Applicable only in PM5660 / PM5661 / PM5760 / PM5761 / PM5660L / PM5760L meter models.
You can configure toroid settings for RCM using the display.
  1. Navigate to Maint > Setup .
  2. Enter the setup passcode (default is “0”), then press OK.
  3. Navigate to RCM .
  4. Select I5 Toroid (Turns) or I6 Toroid (Turns) , then press Edit.
    NOTE: The default toroid turns setting for I5 and I6 is 1000. The I5 Toroid (Turns) and I6 Toroid (Turns) can be set from 300 to 3000.
  5. Modify the parameters as required, then press OK.
