◆ o5: Log Function
The data log function saves drive status information as a CSV file in the micro SD memory
card in the keypad. Monitors Ux-xx are the source of data log information.
There are two types of data log functions:
 Long-term data log: Saves data continuously over a long time period.
 Short-term data log: Saves data for a certain time period before and after the detection of
a trigger with a short sampling cycle.
You can record a maximum of 10 monitors for long-term data logs and a maximum of four
monitors for short-term data logs.
Change the LCD keypad screen from the main menu to the Diagnostic Tools screen and
select the data log function. Set the number of the monitor to record, the sampling time,
and the trigger, then start to record the data log.
