Evaluation of up to 16 variables
Up to 16 variables can be calculated from the four connected probes/sensors. This is the sum of the measured and calculated values. The calculated values can be the result of conversions between channels, e.g. the difference of two connected temperature probes. Detail of the Multilogger LCD display.
The measured values are stored in the internal non-volatile memory. The memory capacity is up to 1 million values. The logging mode can be set as non-cyclic, when logging stops after filling the memory, or cyclic, when after filling the memory the oldest stored values are overwritten with the new ones.
Measured values are displayed on the display with backlight option and the ability to change the size of the display digits.
Power supply
Multilogger can be operated from an AC adapter or from rechargeable batteries with charging capacity. Batteries are always part of the device (you can also use standard AA alkaline batteries). The batteries power the device for several months.
While using the AC adapter, the batteries provide backup operations and allow logging and measurement during a power outage.
Alarm limits and alarm indication
It is possible to set two independent alarm limits for each channel (i.e. measured or calculated value).
Alarm signaling can be acoustic (integrated acoustic warning), visual (LED, LCD)
Communication interfaces
The Multilogger is always equipped with a USB connector for communication, data analysis and also for charging the rechargeable batteries.
