 Note 
*Please note that the resolution of the measured 
value depends on the resolution of HI SET setting.  
 Note 
The LO SET setting is limited by the HI SET 
setting. The LO SET limit cannot be greater than 
the HI SET limit. 
When setting the current, be aware that a 
maximum of 200VA can be set for ACW and 50W 
for DCW (GPT-98XX) or 500VA and 100W, 
respectively for GPT-99XX/99XXA.
