2.2 USE
➢The LM- U Pro data loggers (with an External Sensor) are used to save and read out
individual external sensor reading a measurement series. They have been specifically
designed for monitoring the storage and transportation of product subject to cold chain
requirements.
➢User can fully configure parameters like –Start delay, alarm high/low limit, sensor type,
temperature unit, store interval etc. User can also set the information like, username and
job description.
➢Acceleration readings are monitored throughout the duration of the measurement
program and saved when the set limit value is exceeded.
➢Data logger programming and measurement report output are implemented via CSV, PDF
files, LMView software needs to be installed.
➢Data loggers come with individual NABL traceable calibration certificate.

Note: For Technical reasons, the display intensity of liquid crystal display becomes lower at
temperatures below 0°C. This has no influence on the measuring accuracy. For technical Reasons,
the battery performance decreases at lower temperatures. We Recommend the use of fully
charged batteries to avoid a reset of the instrument at low temperatures.
