ALARM OPERATION WITH HYSTERESIS & AUTO. RESET (OS-MINI & OS-MINI22)
DATA LOGGING (-MA-R-D, -C4-R-D, -CRT, -BRT MODELS)
The OS-MINI and OS-MINI22 can be used as standalone data loggers. OS-MINI models MA-R-D and C4-
R-D as well as OS-MINI22 models -CRT and -BRT include a MicroSD card slot for data logging, which can
be configured via the touch screen interface. The user can select the sample rate and the number of
samples to be taken and schedule the data logging to start at a certain time.
With a 2 GB card, the user can store 28.4 million readings, which provides almost 1 years’ worth of data at
the fastest possible sample rate of 1 per second. Data is stored on the MicroSD card in .csv format and can
be viewed and edited easily using spreadsheet software. A MicroSD card with SD card adapter is available
as an optional accessory.
The MicroSD card slot and battery holder are located on the touch screen circuit board in the lid of the OS-
MI
NI. Readings are time and date stamped using the sensor’s internal clock. The clock is reset when the
power is disconnected, or it will continue if the optional battery is fitted.
