Before starting a formal measurement, press MONITOR to check measured values
as needed (p. 40).
When you have confirmed that the settings are correct, press
START to start formal
measurement (p. 36).
Pay attention to the following items while measuring.
• If a power outage affects only measurement units or wireless loggers

Data during the outage will be treated as lost. Measurement can be continued once
power is restored.
• If the outage is limited to the instrument

Set the smart backup setting to on. Recording will start automatically when power is
restored. Since measurement data from before the outage will not be stored in the instru-
ment’s internal buffer, it is recommended to automatically save data to the included or
optional SD memory card. Data will be lost while the power to the instrument is inter-
rupted, even if measurement units and wireless loggers continue to receive power.
Both measurement units and wireless loggers have internal backup memory.
When communications are restored, measurement units will retransmit (65,536/n) data
points (where n indicates the number of channels) to restore the data on the Wireless
Logging Station.
If there are multiple units to which communications are restored, data will be restored in
the order in which the units are reconnected. For example, a communications failure can
last for about 72 minutes without loss of data when measuring 15 channels of data at a
recording interval of 1 sec. with a measurement unit.
