GRAPHIC DISPLAY
Each Log4 can display readings in both numeric and graphic formats, with a high refresh rate, and very low power consumption. The display offers great sunlight readability and includes an adjustable backlight for low light viewing.
BATTERY POWERED
Each Log4 device is independently powered by a compact internal lithium polymer battery. This allows for measurement with greater accuracy as the Log4 itself draws no power from the supply of the device you test.
ALARMS
Alarm thresholds can be optionally set to trigger both audible and visual alarms. The communications protocol also allows for seamlesss event-based broadcast of these alarms.
OPEN PROTOCOL
Data is streamed from the Log4 via both USB and TTL level serial connections. The format of the transmitted data is an open protocol which can be utilized by devices such as an Arduino or Raspberry Pi.
ISOLATED SERIAL
Both data terminals are isolated from the measurement connections so that the connected PC and the devices being tested are protected from potential earth loop sand voltage spikes.
.CSV FILE FORMAT
Logged session data is recorded to amicro-SD card in standard .csv format.Your data can be readily opened, reviewed, edited, and plotted using standard spreadsheet applications.
TERMINAL CONNECTION
Alternate connection can be made via spring terminals so that you can wire theLog4 directly into a circuit and test a wider range of voltages in numerous other measurement applications.
DESKTOP APPLICATION
Each Log4 partners with a freely downloadable desktop application that supports both Mac and PC platforms. This software can be used to display detailed real-time graphical and statistical information.
