The VR-71 data logger measures and records voltage signals within a measurement range of DC(±)15V.
It can record signals of 1-5V / 4-20mA as welll as output signals from a variety of sensors.The most impressive feature is the software function that allows you to create your own dot matrix patterns for unit display and then change the recorded voltage signal into the desired unit and display accordingly to match your measurings.

Measure and Record with 2 Channels on 1 Unit

It is possible to measure and record on two channels with 1 unit. These two channels make it possible to obtain reliable readings when measuring two related phenomena. By pressing the DISPLAY button, you can choose to set the LCD display to show both channels' readings alternatively, show one channel as a fixed display or show neither channel.

Choose the Display Unit

Of course you can display the voltage reading as is, or by using the software to select the desired scale, convert and display the readings in the unit of your choice.

Unit Display

It is possible using the software to create and edit dot matrix patterns to be used in the LCD as the unit of measurement.

Select from 20 Recording Intervals / Shortest at 0.02 seconds

Recording interval can be selected from 20 choices ( 0.02sec to 60 min ). Tere are also two Recording Modes to choose from : One-time or Endless.

Data Capacity : 8000 Readings x 2 Channels

Each channel can record up to 8000 readings. At a recording interval of 60 min, ( the longest possible recording interval ) that gives you one year of continuous recording capability.
