The VR-71 data logger measures and records voltage signals within a measurement
range of DC(+/-)15V.
It can record common signals, such as 1-5V/4-20mAas well as output signals from a variety of sensors.
The most impressive feature is the software function that allows the create of 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.
*Record Output Signals from a Variety of Sensors.
*Pressure, Water Level, pH, Density, Opaqueness, etc...
*Voltage Management of Electrical Circuits.
- Measure and Record with 2 Channels
- Choose the Display Unit
- Auto-Range Function /±Input
- Select from 20 Recording Intervals
- 9 Months of Continuous Use on 2 AAA Alkaline Batteries
- Reliable Backup Function
- Easy to Read Multi-Functional Display
- Logging Capacity: 8,000 Data Sets
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.
You can specify to convert the scale by specifying values at 2 voltage points or by using the conversion equation of y=Ax+B.
(y stands for the value after conversion and x is the voltage input directly from the sensor.)
EX: At 2 specified points: convert input voltage of 0v to 100 and input of 5v to 5000.
EX: Using the equation y=Ax+B: y=10x+15.
It is possible using the software to create and edit dot matrix patterns to be used in the LCD as the unit of measurement.
±1V, ±2V, ±6V, ±15V.
[When Battery Power becomes Low]
When battery power becomes low a battery life warning will appear on the unit's display indicating that the battery should be changed. If within a short time the battery is changed, measurement and recording will not be interrupted and there will be no data loss. If the battery is not changed the unit will automatically go into SLEEP mode whereby measurement and recording will stop but, due to our BACK UP FUNCTION, data will not be lost and will remain saved for up to one year.
If while recording, the power switch is accidentally turned OFF, data will not be lost but will be saved for up to one year from the time it was switched OFF.
2:The recording status will appear.
ON:Recording in progress.
BLINKING:Waiting for programmed start.
3:After every 2000 readings the scale will be marked from left to right.
4:ONETIME:When the number of recorded readings reaches 8000, "FULL"will appear in the unit's LCD display and recording will automatically stop.
ENDLESS:When the number of recorded readings reaches 8000, the oldest data reading will be overwritten and recording will continue.
5:When the battery power becomes low, this will appear in the LCD display. If the battery power becomes even lower, "SLP" will appear and normal operations will stop. If the signal appears, please change the battery as soon as possible.
6:The unit of measurement for the display will appear.
7:Current measurements or operational messages such as "FULL" or "SLP" will appear.
Calculates remaining battery life and displays a battery warning to indicate the need for a battery change.
