WebStorage] , by tapping on a Base Unit on the list you will move to the Settings Menu for that Base Unit.
Upon opening, a message will be displayed showing the status of the Base Unit when the app communicates with the Base Unit via Bluetooth or via T&D WebStorage Service.
If an error message is displayed, please refer to the message, check the settings and if necessary make changes.
When you see the [There are unapplied settings] message:
Since the RTR500BW checks T&D WebStorage Service every 10 minutes for pending settings, some settings made from the [WebStorage] tab may have not yet been applied and are still pending. By tapping on [View Pending] it is possible to check on which settings have yet to be applied and cancel settings if desired.

Make settings for the recording method for measurements.
Instantaneous Value: Records the instantaneous value at the set recording interval.
Average Value: If the recording interval is less than 20 seconds, the recorded value will be calculated from measurements taken every 1 second. If the interval is 20 seconds or longer, the recorded value will be calculated from measurements taken every 2 seconds.
Make settings for when using scale conversion. This has no reflection on what is displayed on the LCD display of the Remote Unit.
Use y=ax+b: Select this when the values for both the slope (a) and intercept (b) are already known.
Specify 2 points: Select this when both the input values from the sensor and the post-conversion values are known at two points. (See the sensor user’s manual for details)
Select ON if you wish to control the sensor power supply. It transmits a preheat signal that is synchronized with the recording interval to turn sensors ON before and OFF after measuring and recording.
Make settings here for the range of measurement. The Remote Unit LCD will change to reflect the set measurement range.
V: This will fix the measurement range to the V range (display range: 0.000 to 22.00V / auto decimal point)
mV: This settings will automatically switch the measurement range for the Input Module between "mV Range" and "V Range" depending on the measurement. (display range: 0.0 to 999.9mV / auto decimal point)
Make settings here for the pulse signal type to be recorded.
Rising: Records the number of rising pulses during the set recording interval.
Falling: Records falling pulses during the set recording interval.
This filter should be turned on when connecting a device such as a switch or relay where input chatter is expected.
Select the target item from Pulse or Event (rising or falling) and judgment time for warning monitoring.
Display resolutions for monitoring each target item are follows:
Pulse: one-sixtieth of recording interval (minimum of one second)
Event: 1 sec
Make settings for the sampling interval, calculation percentage and calculation time period.
The wireless communication range can be extended by placing a Repeater in between a Base Unit and a Remote Unit.
Specify the Group to which the Remote Units are registered that you wish to add a Repeater.
Will be displayed as <Model_Serial Number>.

If desired for identification, enter a unique 3 digit (alphabetic and/or numerical) name for the Repeater.
Here you can switch Bluetooth Communication ON or OFF.
Set a 4 to 8 digit numerical Repeater Passcode used for pairing.
The same passcode can be used for all devices.
Here you can make Wired and Wireless LAN Settings as well as check the network connection status.
Note that changes cannot be made via WebStorage.
The default setting is Auto (IP). Normally, there is no need to change settings.
