The 24-hour performance data registers (

Figure 17

) are 

available for the current day and the past 30 days. 

The 30-day performance data registers (

Figure 18

)

 are 

available for the current 30 days and three previous 

 

30-day periods. All performance data registers can be 
reset by the

 Reset Data

 option. This reset must be 

confirmed by choosing 

Y

 on the warning screen (not 

shown).

The 

MSEC

 (Measured Seconds) parameter is a count of 

how many seconds have elapsed during the current 
interval displayed on the Performance History screen. 
The count will reset to zero when the performance 
history data is reset, or if the date or time is changed. 
The count will automatically restart when the current 
interval being observed ends and a new current interval 
begins.
