are automatically read and filled in the Min/Max boxes on this screen. An example is
shown on Fig.5.15.
In the field “Measure period” the user can make the measuring faster or slower.
Max and Min fields permit user to change graphic scales.
When the measurement is started and Do log field is ticked data will be acquired in a
log.csv file. If the SMBus mode is selected the following RAM registers will be logged in the
log.csv file (See MLX90614 datasheet for more information):
● Ambient sensor data - SMBus RAM address=0x03h
● IR sensor 1 data - SMBus RAM address= 0x04h
● IR sensor 2 data - SMBus RAM address= 0x05h
● Linearized ambient temperature Ta - SMBus RAM address =0x06h
●Linearized object temperature (IR1) T
●Linearized object temperature (IR2) T
If PWM mode is selected logged data will depend on the chosen PWM structure.
Every time a measurement is started the log file is continued, with the entire EEPROM
saved as new heading row.
Note 10: In Regional and Language Options (available from Start/Settings/Control panel) list separator need
to be “,” and decimal symbol – “.” in order to get the CSV log file opened in an easy to use form in EXCEL.
Note 11: Note that the CSV log file is the same for all measurements, there is not a separate file for every
module that is measured.
To change the temperature measuring unit (°C, °F or K) and to relocate the log.csv file:
