4 General information
The 2nd Generation yoyo-series consists of a large variety of loggers. The full range of
loggers is shown on page 7.
Many of the yoyo-series of loggers have internal sensors such as humidity/temperature,
barometric pressure and light.
Other models have sensor slots to which external sensors may be connected. Some of
these sensors are combined sensors (for example humidity and temperature). Such a
combined sensor (for example YSRHT-120-2) can be connected to a single slot.
The loggers have a memory capacity for 4,000,000 readings.
It can be set to either “stop-when-full“ or ring-buffer mode (continuous mode).
The device offers an internal battery monitoring. YoyoView software will warn you if you
need to replace the battery. In addition, the LED flashing periodically indicates the need
for the battery to be replaced (see chapter 0, understanding LEDs for further information).
The device can be controlled over the USB cable. It only takes a few clicks to select the
relevant parameters.
If you require information or technical support for 1st Generation yoyo loggers, please
contact Grant instruments support@grantinstruments.com .
1st Generation models are identified by model prefix YL e.g. YL-T10

4.1 Installing batteries
The logger’s power supply is provided by a 3.6V lithium battery.
The following list shows which battery shall be used for your logger:
- Lithium battery SL-550/S for 2YL-T14-4M/T14-E-4M and 2YL-RH24-4M/RH24-E-4M
- Lithium battery type SL-750/S for all other models
The logger 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).
To insert a battery into the datalogger, unscrew the
back cover of the logger then insert the battery keeping the correct polarity.
When the battery has been fitted the LED on the front of the logger will start flashing in
red/green/blue after a few seconds to indicate it is operating.
Battery life
The battery life depends mainly on the logging interval selected. The table gives an overview for typical
intervals.

Battery life
>1 min 4 years

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