Tinytag View 2 data loggers show the value that they are
currently reading on their display. If your data logger has two
channels, readings will alternate between the two properties every
Apart from showing the readings that are currently being
recorded, a View 2 data logger has a number of other indicators
across the top, bottom and left-hand side of its display.
These indicators are as follows:
Top of the display: Alarms (Hi1, Hi2, Lo1 and
A View 2 data logger can be programmed with two alarms.
This can be a combination of two alarms on one channel of the
logger, or - if a dual channel logger is being used e.g. a
temperature and relative humidity data logger - one alarm can be
set per channel. The numbers following Hi1, Hi2 (high alarms) Lo1
and Lo2 (low alarms) refer to the two channels.
Alarms can be cleared from the logger's display using the
Tinytag Explorer software.
Left-hand side of the display: Low Battery
The indicator that lights on the left-hand side of the logger's
display is a low battery indicator. This lights next to a low
battery icon on that is printed on the case of the logger.
When this display indicator lights, the logger will have
approximately two weeks of battery life remaining
before it will stop recording. It is recommended that the battery
in the logger should be replaced as soon as this indicator lights
to avoid the loss of any data. Replacement batteries for our data
loggers can be purchased in service kits which can be found here:
Tinytag service kits.
Bottom of the display: Property being
The indicators along the bottom of the display show which
channel the data logger is currently showing readings from.
If the logger has two channels, readings will alternate between
the two properties every few seconds, and a marker will move
between the two properties to indicate which property is being
shown (mA, mV or V). If a voltage or current logger has been
programmed with a custom education, a segment will light beside the
In the case of single channel voltage and current loggers, the
indicator will show which property the logger is recording
The display will also indicate if a temperature logger is
showing readings in °C or °F.
In addition to the above indicators, the logger also shows some
text status messages, as below:
- wait - the data logger is set for a delay start
- trig - the data logger is set for a trigger start
- err9 - data logger error. If you see this message on your data
logger, please contact your supplier or Gemini Technical Support
for further information.
