Instruction Manual
1.3 RMS Mini Data Logger
The mini data logger carries out measurements in a fixed interval, saves all measured data and sends it to the
database by radio link. Should the connection be lost, the logger stores the data intermediately to protect data
integrity and fills up the data gaps when the connection has been restored. Depending on the variant, the mini
data logger records various parameters: temperature, current, voltage, temperature & light or switch contact.
The device uses a battery as the power supply.
The mini data logger provides the following basic functions:
o Measurement (temperature, current, voltage, temperature & light or switch contact)
o Recording of up to 10,000 data points
o Transfer of the recorded data to the RMS software
o Calibration and adjustment of the sensors
o Firmware update
1.4 Power Supply
The mini data logger has two 3.6 V lithium thionyl chloride AA batteries. The power supply of the batteries
suffices to carry out measurement and data storage and to operate the wireless interface.
Note on the batteries:
The AA batteries are lithium thionyl chloride batteries available in the industrial trade. All RMS input modules
are designed for this type of battery. Only batteries of the same type or with identical characteristic values may
be used as replacement batteries.
