1.5.2 How to set parameters
At any test interface, turn coarse regulation/fine regulation knob to move cursor to select
variable, press Enter key to set the value of variable. Coarse regulation knob can set
three digits ahead of radix point. Fine regulation knob can set two digits after radix point.
For three units, AC pick-up value, DC pick-up value and synchronization test, by
selecting variables can set corresponding parameters before or after starting test; for
other test units, by turning coarse regulation/fine regulation knob can change output of
variables before starting test, the parameter setting cannot be changed after starting
test.
