Q&A about Operations after Settings
Q1: Communication errors occur frequently, why and what can I do?
A: If Wireless Communication Errors are occurring:
Take the RTR-500DC and carry it to a spot where communication is possible. In addition please check or try the following items.
- Try placing new batteries in the Base Unit, Remote Unit and or Repeater.
- Make sure that not more than one is trying to communicate at the same time; this will cause communication errors.
- The radio signal strength may be weak.
- Check to see if the RTR-500 series loggers are using the same frequency with other wireless communication devices for transmission. If they have the same or nearly the same frequency, change either one to avoid interference.
* IMPORTANT
In order to change the frequency channel for the RTR-500 series loggers, you must first delete all Remote Units (or Repeaters) with the same frequency channel setting, and then register them again. In the Remote
Unit (or Repeater) Registration window, change the Communication
Frequency Channel and then click "Register".

The communication errors may be caused by insufficient memory in the

If Optical or Cable Communication Errors are occurring:
- Please check the following, wait and try communication again.
- Try placing new batteries in the Base Unit and Remote Unit.

Q2: Is it possible to adjust or alter recorded data that has been downloaded by the RTR-500?
A: In order to maintain the integrity and trustworthiness of the recorded data, the software has been designed to not allow modifications to be carried out on actual recorded data. If it is necessary to edit recorded data, in the Temperature / Humidity Graph or the Multi-scale Graph save the data to text file and use a common spreadsheet software such as Excel to edit the text file data.
Q3: Can I merge all the RTR-574 / 576 data that has been downloaded via wireless communication into one set of data?
A: Although data downloaded from the RTR-574 is stored as two sets of data: "Illuminance and UV Intensity" (CH1 and CH2) and "Temperature and Humidity" (CH3 and CH4), it is possible to display and save them as one set of data.
Moreover, data downloaded from the RTR-576 which is also stored as two sets of data: "CO2 Concentration" (CH1) and "Temperature and
Humidity" (CH2 and CH3), can be displayed and saved as one set of data.
This can be done in either of the following two ways:
Opening from the Multi-scale Graph
In the Multi-Scale Graph, in the [File] menu click on [Open] and select the downloaded data file you wish to open.
Opening from the RTR-500DC Manager
1. Connect a RTR-500DC via USB to your PC and open the RTR-500DC
Manager.
2. From the Data Info List, select the set(s) of RTR-574 / 576 data you wish to save to your PC by using the <Shift> key or the <Ctrl> key.
3. In the [Communication] Menu, click on [Download Data] to save the recorded data to the PC.
4. After selecting data in the Data Info List, right click to open a context menu from which you can select [View Graph]. The [Save as...] window will appear.
5. After assigning a name and saving the data, the Multi-scale Graph will open where you can view the Graph for the selected data.

Q4: When registering the Remote Unit I made settings for "Scale Conversion", but in the Remote Unit and Data Collector scale conversion is not being carried out. Why?
A: The measurement values and graphs displayed on Remote Unit's and
Data Collector's LCD will not be converted, and therefore the measurement before scale conversion will appear. However, the downloaded data has the info for the scale conversion settings which you have made, and you can view the converted measurements in graph form by using "RTR-500DC Manager" to download data to a PC and "Multi-Scale Graph" to open the downloaded data.
The following Remote Units can use "Scale Conversion":
RTR-505-V (Voltage)
RTR-505-mA (4-20mA)
RTR-505-P (Pulse)
* What is "Scale Conversion"?
Make settings here to view the downloaded data in the desired unit. For details, see [Remote Unit Registration] in the "RTR-500DC Settings Utility" or "Multi-Scale Graph" application's Help in the [Tool] menu.
