The OMYL-M32 voltage data logger has two channels forrecording extra-low voltage levels in the millivolt region(±5 mV, ±10 mV, ±20 mV, ±50 mV, ±100 mV, +-1000 mV)and also common reference voltage measurements, e.g.standard analog outputs (0 to 1 V, 0 to 5 V, 0 to 10 V).This data logger is available with standard memory of100,000 readings (OMYL-M32) or expanded memory of4 million readings (OMYL-M32-4M). Both models can beused for recording small measurement signals from aWheatstone bridge, force or range sensor, strain gauge,or other extra-low voltages applications. This data loggerprovides constant bridge excitation current for straingauge sensors. These devices are programmable so thatyou can log data from either one or two channels.Both models feature a 20 bit analog to digital convertergiving a resolution of up to 0.15 μV. The data logger’smeasuring range is user-selectable, enabling you towork with measuring ranges from 10 mV to 20 mV at thesame resolution.
The storage medium is non-volatile flash memory sono data is lost if the battery becomes discharged. Datalogger setup as well as data retrieval is accomplishedusing the included standard OMYL-SOFT software.Downloaded data is stored in the OMYL-SOFTsoftware as a text file for viewing in third party softwarepackages or Microsoft Excel. The OMYL-SOFTstandard software does not include any graphingfunctionality. Graphing and analyzing downloaded datafiles requires the OMYL-SOFT-PLUS version of thesoftware (sold separately).
