True R.M.S.Voltage Recorder

The VR is a state of the art display & logging system designed to monitor and record the R.M.S. voltage of 230/ 240 VAC single phase supplies for voltage fluctuations in the range 160-270V rms.

The unit has a 4 digit LED display for the continuous display of the voltage. The date and time of the device clock can be viewed & set through the user interface software. The starting time of voltage recording can also be set through the user interface software. The minimum recording time interval is 1 minute and can be set in the range 1 to 15 minutes in 1 minute steps. The maximum number of records is 9999.Visual indicators are provided for power-on, recording data and the battery condition.

After acquiring data over a given recording period, the data can be downloaded to a personal computer  for analysis.  For this purpose, unit is supplied with a user friendly software interface and a data cable.

Printed circuit board is enclosed in a metal container with suitable dimensions to be placed inside the box, and the product is designed to stand a maximum ambient temperature of 500 C.
