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.

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.

additional information about the logger model
and status.

Grant Instruments
30641 V1.3 Yoyolog
Page 13 Operating Manual
The full serial number, logger status, number of channels, firmware version,
battery capacity, memory percentage used and the actual logger time will be
displayed.
Logger Status gives information about the status of the logger. If the status is
sleeping”, no readings are being taken and the logger is waiting to be setto log.
If the status is “logging” the interval set will also be displayed.
The battery voltage is an indication of the battery life remaining. It is recommended
keeping track of the battery usage or simply use a new one if the status of the battery
is unknown and data is important. Refer to table in chapter 4.1 to understand the
impact of the interval on the battery life. The logger works with a lithium battery whose

7 Logger Control
Once the logger has been selected, right click to enter
the menu to control the logger.
A logger control window is opened and will show the
following functions Metermode, Start/Stop Logger,
Download Data and Logger Setup.
7.1 Online Meter
In the Logger control window click on Metermode, to
see current logger readings for channels that are set.
Note that the screen shows channels in their numeric
order. That means that first of all, all channels assigned
to slot 1 will be displayed, then all channels assigned to
slot 2 and so on.
Please refer to chapter 7.5 for more information on Slot
numbers and channel numbers.
Note: The logger is mainly used for unattended long term logging, therefore Meter
Mode is used to test the logger and verify that the sensors have been connected
correctly and are providing the correct readings.
When the logger is connected to a USB port it will self heat therefore the internal
sensors may not be as accurate, the values may be up to 2°C higher than the actual
values.
Once the logger has been disconnected from the PC and moved to an external
environment, the internal sensors of the logger may take up to a few hours to stabilise.

In the Start Datalogger window, the Stop condition for the logger can be set.
If the Memory full option is selected the loggers will
stop logging when the memory is full.
If never (cont mode) option is selected the logger will
start to overwrite the oldest readings when the memory
is full.
To set the interval rate of the readings, select the unit ; Hours, Minutes, Seconds or
Hertz and define the Interval Value.
Examples: to log every 10 Minutes, select Minutes at the Section Interval and enter
10 as the Interval Value.
To log at 5 Hertz, select Hertz at the Section Interval and enter 5as the Interval Value.
Finally, a Description of up to 46 characters can be entered. This Description will be
