The data being displayed is inaccurate or not what you expect.

Incorrect setup values.

Check that You use the correct f(x) formula

Incorrect voltage inputs.

Check power meter voltage input terminals to verify that adequate voltage is present

The power meter is wired improperly.

Check that all wires are connected correctly and that they are energized. See “Wiring Diagrams” of the device.

The sensor does not appear in the Vutlan monitoring interface

Communication lines are improperly connected.

Check the 6P4C RJ11 communication cable.

The communication cable is inserted into the wrong port.

6P4C RJ11 communication cable must be inserted into the analog port of the Vutlan monitoring system.

The sensor is always in alarm state.

The cable touches itself.

The cable can not touch itself. It needs to be straightened. Please check if the cable is bent anywhere.

The cable is twisted or pressed down too much.

Do not twist or press down the cable too much. This may lead to deformation. The cable has two sensing wires, these wires can not touch each other.

The cable is located on a conductive surface.

Do not put the cable on a conductive surface.

The cable is damaged

Check the continuity of the cables with a multimeter. Let’s call each wire A and B:

If the cable is not damaged, you should get the following results

1. A-A: there’s a continuity. (I thinks it’s good)

2. A-B: there’s a continuity. (I think there shouldn’t be any)

3. B-B: there’s a continuity

If the cable is damaged, you will get:

1. A-B: there’s a continuity. There should not be a continuity. The wires cross each other somewhere.

or

2. B-B or A-A: no continuity (the wire is damaged).
