6.2.4 LVRT/HVRT Parameters
LVRT/HVRT” is used to set the LVRT and HVRT parameters. Move the
cursor to this item and press the ENT key to set the parameters. There are
7 pages of LVRT/HVRT parameter settings. These can be changed in the
menu tree or by the LVRT (Figure 6-11) and HVRT (Figure 6-12) graphs.
