3 Quickstart
Receive readings in only six easy steps:
Install the USB driver from the USB stick:
execute \USBDriver\USBXpressInstaller.exe
 YoyoView for Windows
\setup.exe
Open the logger by unscrewing its rear cap. Insert the battery. Connect the USB
cable to the respective ports of the logger and the PC.
The Operating System will detect the device automatically. Wait for the notice that
the device is ready to use.
Start YoyoView. The program automatically recognizes the logger and displays a
picture of that logger.
Double click on the picture to select the logger.
Right Click on the logger and select Metermode. After a few seconds online
readings from the connected logger will appear on the screen.
Start logging in two additional steps
Again Right Click on the logger picture and then click on Start Logger.
Click on Start Logger now. The logger will start on the nearest minute with a preset
logging interval of 10 seconds. The loggers blue LED will flash accordingly.
Viewing a Graph of measured data in just another step
Click on Download Data.
Stored readings will be downloaded, saved as an ASCII file, and a graph is displayed.

4 General information
The yoyolog series consists of a large variety of loggers:
Some have an internal sensor only. Others have inputs for external sensors, whilst
some have both sensor types.
A full list of models can be found on our website.
The logger uses sensor inputs to which external sensors are connected. Some of the
sensors are combined sensors, such as the YS-RHT for measuring temperature and
humidity. This sensor uses a single input connector.
The loggers have a memory capacity for 100,000 readings which can optionally be
extended to 4,000,000 readings.

The device can be controlled over the USB interface using YoyoView Software. It only

Optionally for high-temp-applications a CR2450HT battery can be supplied.
The device offers internal battery monitoring. YoyoView will indicate when the battery
will require replacing. In addition, the LED flashing periodically indicates the need for
the battery to be replaced (see chapter 0, understanding LEDs for further information).
In order to insert a battery into the datalogger, unscrew the back cover of the logger
then insert the battery keeping the correct polarity negative pole downwards.
When the battery has been fitted after a few
seconds the LED on the front of the logger will
start flashing in red/green/blue to indicate it is
operating.
The battery life depends mainly on the logging
interval selected. The table gives an overview for
typical intervals.

Some other factors reduce battery life. E.g., low temperatures decrease battery life.
Downloading data or operation in MeterMode will also cause an increased energy
consumption, which further decreases battery life.
