Note 1: Stand-alone mode supports the following sensor types: PAN10, PAN12, PAN14. It

does not currently support PAN-42.

Note 2: The calibration key is a unique, per-sensor, value used by the bridge to calibrate

each reading for accuracy. It is a mandatory, sensor specific, value.

Note 3: When clicking 'Get Key, your browser communicates with PowerRadar to get the

calibration key. It is, therefore, essential that the laptop has Internet connectivity.

Note 4: If having issues retrieving the calibration key, please contact support who can

provide an offline list of calibration keys to be entered manually.

View Sensor Readings

Sensor readings are available in the 'Sensors Tab'. Each allocated sensor will display the last

received reading. A new reading will override the previous reading.

1. Navigate to the 'Sensors' tab. This Tab is only when 'Connection Setup' > 'Enable Modbus

TCP' is checked.

2. Allocated slots will show the following values:

a. Sensor S/N: The serial number of the allocated sensor

b. Current [A]: The last calibrated measurement in Ampere.

c. RSSI [dBm]: The received signal strength of the last measurement.

d. Timestamp: the time of last measurement.

Note 1: The information provided here is also available via the Modbus TCP interface.

Please refer to the Bridge Programmers Guide for more information.

Note 2: The current readings shown here have already been individually calibrated by the

bridge for accuracy, using the calibration key.

Note 3: PAN 10 and PAN 12 current readings can be used as-is. For PAN 14, these values

should be multiplied by the CT-Rate of the CT used.
