 Adjusting the meter in inverter stop state
 Adjustment of output current (  = 1 )
If, when adjusting the meter for output current, there are large fluctuations in data during adjustment,
making adjustment difficult, the meter can be adjusted in inverter stop state.
When setting  to  for fixed output 1 (output current 100% equivalent), a signal of absolute
values will be output (inverter's rated current = 100%). In this state, adjust the meter with the  (Meter
adjustment) parameter.
Similarly, if you set  to  for fixed output 2 (output current 50% equivalent), a signal that is sent
out when half the inverter's rated current is flowing will be output through the FM terminal.
After meter adjustment is ended, set  to  (output current).
 Other adjustments (  =  ,  to  ,  ,  ,  ,  to  )
 =  : When fixed output 3 (other than the output current) is set, a signal of the value for other
monitors is fixed at the following values and output through the FM terminal.
100% standard value for each item is the following:
 = 0 , 2 , 12 , 
 = 3 , 4
 = 7
 = 9 to 11
 = 13 ,  ,  ,  : Maximum input value (10V, or 20mA)
 = 18
 = 24 , 25
