Essential Points for Safety
Introduction

6
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.
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.
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.
4. Do not connect a telephone line or household LAN cable to the LAN terminal on the Power
Monitor. There is danger of the Product malfunctioning.
Precautions for Use
5. 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.
● Time is changed from 8:45 to 9:15.
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.
● Time is changed from 9:18 to 9:28.
8:30 8:45 9:00 9:15 9:30
Data is added to that of 8:45.
Performance data is not lost.
