NAVI functions
(6)-1 LCD brightness
Set the brightness (three stages of bright, middle, and dark) of the LCD backlight.
(6)-2 Screen Saver
Select the time (eight stages of 10 s to 60 min.) you want to specify. The screen is switch to Off state
automatically when the non-operation state continues for a predetermined period.
Turns off the display if not operated for some time to extend the service life of the LCD screen.
If this device runs on a battery pack (B-569, option), the use of this function prolongs the drive time.
(6)-3 Power On Start
Sets the feature which initiates measurement as soon as this device is turned on.
Setting
Disable
Enable
(6)-4 Overvoltage detection function
Set the function to reduce damage of this device when overvoltage is applied.
Setting
Off
ON
•
This function is effective only during free running.
This is not effective during capturing and remote (connection to the PC).
•
This function is effective when the set range is in the range of 20mV to 2V.
This is not effective when the set range is 5V or more.
•
This function is also available for CH set to temperature and humidity.
When overvoltage is detected in the state in which set to temperature and humidity, the input is changed
to voltage input and then changed to the 1000V range.
•
This function is intended to reduce damage from overvoltage, but is not to protect damage. Depending on
the input voltage, the input circuit may get damaged, so be careful not to input any overvoltage.
(For details on overvoltage, refer to "2.12 Precautions to Observe When Performing Measurement".)
Setting
Even when turning On the power, the recording starts automatically.
When turning On the power, the recording does not start automatically.
Even if overvoltage is detected, the range is not changed.
In Free Running, when the voltage exceeding the set range is detected, the range is
automatically changed to 1000V.
