All HS3 and HS4 seriesAll measuring instrumentsCan be used as dataRecorder ortransientrecorder.Data loggerIt is a direct recorddisplayInstruments for signal voltage.

HS3 and HS4 data recorders are availableContinuous recordingpattern，Until itTerminated by user.Simultaneous measurement，Every time a new one is collectedWhen sampling，They willDirectly transmitted tocomputer，They willProcessed and displayedThe required time andStore on hard drive.Any changesinputsignalWill immediatelyvisible.Measurement durationThere is no limit, it can be saved continuously for hours to days.

HS3, HS4 recorders andThe main difference from an oscilloscope is，oscilloscopeMeasure the predeterminedTime QuantityAnd store allmeasurement dataAtInternal implementation of the instrument.whenWhen measuring data，All data will be processedTransfer to computer，thenProcessed and displayed.after，A new measurementWill begin.this kind ofThe measured length and instrumentMemory relatedSo we can'tContinuous measurement, with intervals between each measuring unit.

whenuseThere is no longer a gap issue when the data logger is in streaming mode.

For example, slowly changing in a roomThe temperature of the temperature.AtThroughout the entire process,anychanginginputsignalIt is immediately visible.

The maximum data recording traffic can reach 100KHz/s per second (Chinese English)The text interface makes it clear to customers at a glance
