Do your monitors measure voltage ?

In common with the majority of all clamp based systems we measure current only, not voltage  though we have the facility to change the voltage setting in the software accordingly for your  own circumstances . Clamp based  systems do not require any  alteration to your existing  household wiring and are therefore easily  installed.

We are aware that voltages will vary slightly all the time and if  you require greater accuracy with  real-time  voltage and current  monitoring  we suggest you may require a device that is hard wired into your supply such as calibrated meter.
