Figure 506: User-configurable metering logic operands window
The left side of this screen displays all operands that are currently available to the D90
The metering logic operands are displayed by expanding the Metering entry. Each
operand can be renamed with a user-specified value to provide additional information or
match specific applications.
User Configured Event Name
Range: up to 20 alphanumeric characters
Default: ---
Each available metering logic operand can be renamed. This feature allows users to
rename operands to allow for clearer identification or to match specific applications.
The new operand name appears in protection and automation logic, in settings that take
operands as their value, and in event reports.
The following metering logic operands are available for the D90
alphabetically by operand syntax. If required, these operands can be assigned user-
defined names through the Settings > Configure FlexOperands menu.
