Function description: The settings may be adjusted to the quality of the electricity in use.
e.
Slew Rate: Also called Dynamic Frequency Tolerance. There are 5 different settings
(0.25,0.5,1,2,4 Hz/Sec). The default value is 4Hz/sec.
Function description: "Slew Rate" indicates the tolerance of a device in accepting frequency
variances. The lower "Slew Rate" results in less tolerance but better protection for the connected
loads.

standard mode (setting: 2).
The settable items are sorted by unit as in the following table:
