    Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The G60 applies a cut- off value to the magnitudes and angles of the measured currents.

    Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the G60 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
