• Six data logging areas have been prepared. Each area can save 588 pieces of data (up to
6 items can be set.)
• Data logging cycle can be selected from among 5 minutes, 10 minutes, 30 minutes, 1 hour,
2 hours, 6 hours, 12 hours, and 24 hours, and is controlled by specifying 0:00 of the
internal clock in the main unit as the starting point.
Example
Every 5 min
Every 10 min
Every 30 min
Every hour
Every 2 hours
Every 6 hours
Every 12 hours
Every 24 hours
• For logging, after measurement data within a logging cycle is saved, data is reset to start
the measurement at the next cycle. For example, setting logging cycle of 5 min and
voltage MAX accumulates voltage MAX values every 5 min.
• The number of days for which log data can be saved differs depending on logging cycles.
Every 5 min
Every 10 min
Every 30 min
Every hour
Every 2 hours
Every 6 hours
Every 12 hours
Every 24 hours
• For logging items that can be set, refer to Page A-15.
 CT signal detection

O: With function X: Without function
• When the CT, ZCT is connected, and the current whose measurement value is 2% of the
standard current is supplied continuously for 10 or more seconds, the targeted LED lights.
* Even when the low-cut function forcibly sets the current measurement value to 0, CT
signal detection turns LED ON, if the actually flowing current is more than 2% of the
standard current.
