Settings Tab allows you to access device’s settings. It is divided in few sub-tabs detailed in the following paragraphs.
Wi-Fi Station: see next paragraph for detailed Wi-Fi setup on devices equipped with Wi-Fi extension.
Date and time: this section allows to manually set device’s date and time when no NTP servers are available from your network. Use the Set to browser time button to automatically fill the date and time from your computer’s date. Click the Save button to apply modifications.
Device control: reset device (mandatory to apply configuration changes made to Services) or energy counters.
You can start the Wi-Fi wizard by clicking the button from the Settings – Basic tab.

This tab is reserved for use by DotVision support team for on-site diagnostic.
This tab allows you to edit the device calibration.
Please note that device measurement accuracy is only guaranteed when using the default calibration. Devices are calibrated specifically on a per-device basis by DotVision to guarantee the best possible accuracy over the full input range of the device.
However, for specific needs, it may be desirable to alter default calibration (e.g., improving device accuracy at low input current range or optimize calibration for specific voltage ranges).
Note that default calibration data of the device can always be restored to factory settings.
Following calibration parameters are accessible:
- xVRMS_a: RMS voltage slope,
- xVRMS_b: RMS voltage offset,
- xIRMS_a: RMS current slope,
- xIRMS_b: RMS current offset,
- xWATT_a: active power slope,
- xWATT_b: active power offset,
- xVAR_a: reactive power slope,
- xVAR_b: reactive power offset.
with x = A, B or C for channels 1, 2 and 3 respectively.
To edit a calibration parameter, edit the value in the corresponding field and click the Write button as shown below.
The modification takes effect immediately but will not be persistent after device reboot, unless explicitly saved.
For modifications to be persistent after device reboot, the modifications must be saved by clicking the button
The button will clear all modifications not written to the device
The button will discard all user modifications and reload the factory default calibration parameters.
DotVision calibration procedure uses multi-point calibration along the whole device input range for both voltage and current channels. However, it is possible to achieve good accuracy using a standard 2-point calibration procedure with a stable AC voltage and AC current source. Calibration reference used MUST have voltage and current phase angle configurable between 0 and 90° to enable VAR (reactive power) calibration.
Recommended procedure is described below:
- Set all slopes parameters (xYYYY_a) to 1.0 and all offset parameters (xYYYY_b) to 0.0 from the Settings – Calibration page,
- Go to the Live - Table view page to access DataPoints values for IRMS, VRMS, WATT and VAR measurements, or use the device API to setup your calibration interface. Reading of those values will be required to compute calibration parameters,
- Start with voltage calibration by applying 2 known AC voltage to the device voltage measurement inputs. Recommended AC voltage values of 50 and 230VAC should be used,
Use those measurements to compute xVRMS_a and xVRMS_b calibration parameters for each channel,
- While applying nominal AC voltage at voltage measurement inputs, apply two known AC currents through the current sensors with a 0° phase angle to AC Voltage. Recommended AC current of 5% and 100% of current sensors range is recommended. For Rogowski coils calibration, due to their high linearity at high currents, AC currents of 5% and 30% can be used.
Use those measurements to compute xIRMS_a and xIRMS_b for each channel, as well as xWATT_a and xWATT_b,
- While applying norminal AC Voltage at voltage measurement inputs, apply two known AC currents through the current sensors with a 90° phase angle to AC Voltage. Use same AC current range as for the previous step,
Use those measurements to compute xVAR_a and xVAR_b.
- Report calculated calibration parameters to the Settings - Calibration page and save changes to the device.
Note 1: it is recommended to perform calibration after a warm-up period of about 10 minutes at room temperature.
Note 2: it is recommended to perform average calculation on all raw values red from the device under calibration. For WATT and VAR calibration, it may be preferable to use the difference between WATTHR and VARHR values at beginning and end of the calibration period instead of average of WATT and VAR values. Proceeding this way improves measurement accuracy as the calculated value will be intrinsically averaged over the measurement period.
