How it works and how to install it
The indicator measures AC voltage directly from the mains, and current via the CT coil which is mounted on the phase conductor. The LED display continuously updates the values, allowing instantaneous monitoring of electrical parameters. Installation is done by inserting the indicator into the 22mm opening in the electrical panel, connecting the voltage cables, and passing a conductor through the CT coil. Basic knowledge of electrical engineering is required — if you are not familiar with working in electrical panels, call a certified electrician.
Frequently Asked Questions
Can I install it myself or do I need an electrician?
If you have experience working with electrical installations and comply with safety regulations, you can install it yourself. Otherwise, it is recommended to call a certified electrician for interventions in the electrical panel.
Does it display all 3 values simultaneously or one by one?
It displays all three values simultaneously on the LED screen — voltage, current, and frequency are visible at the same time, without switching.
Is the CT transformer coil included in the package?
Yes, the CT current transformer coil is included along with the indicator. You have everything you need for complete installation.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
