Precautions For Use - Delta R4E User Manual

１. The Product is not a specified measuring instrument that passed any certification criteria of any
designated accreditation organization as prescribed by the Measurement Act. The Product may
only be used to provide a rough indication on the amount of power.
２. A touch panel type liquid crystal display has been adopted for the Product. Do not press or hit
hard on the surface of the display.
３. The Product may malfunction or may be damaged by static electricity. Be sure to remove any
static electricity on the body, through such means as touching a metal object nearby, prior to
coming into contact with the Product.
４. Do not connect a telephone line or household LAN cable to the LAN terminal on the Power
Monitor and the Wireless Communication Unit. There is danger of the Product malfunctioning.
５. Insert the AC adapter of the Power Monitor in the power outlet at all times when using the Product.
Removing the AC adapter from the power outlet will prevent the system from obtaining detailed
data during such period and result in the omission of graphs and the like.
６. Keep the power supply (breaker for solar power generation) of the Meter turned ON at all times
when the Product is in use.
７. Reverting the date and time by at least a 15 minute interval into the past will result in the loss of
performance data. Set the date and time correctly.
Example : [A case where performance data is lost]
The time is inadvertently changed from 9:15 to 8:45 and then reverted to 9:15.
The performance data starting from 8:45 onwards are added to the performance data from 8:45
and the performance data for the period since 8:45 is lost. Lost data cannot be restored.
● Time is changed from 9:15 to 8:45.
Data is added to that of 8:45.
8:30 8:45 9:00 9:15 9:30
Example : [A case where performance data is not lost]
The time is inadvertently changed from 9:28 to 9:18 and then reverted to 9:28.
The performance data from 9:15 is fixed as of 9:30 and as such, the performance data is not lost,
as long as the time change does not extend to at least a 15 minute interval.
● Time is changed from 9:28 to 9:18.
8:30 8:45 9:00 9:15 9:30
