kMeter Manual

Below is an overview of how to use the kMeter feedback system for the kBox.

Quick Start Guide

To quickly get up and running with the kMeter read one of our Quick Start Guides (kMeter II, kMeter Module).

Using the App

For an explanation of the different functions in the kMeter App, read the manual for App Usage.

For a presentation of the kMeter, watch this video.


The kMeter II operates with two AA batteries, which are pre-installed upon assembly at our factory in Sweden. You can simply connect to it through the kMeter app. To replace the batteries, remove the snap-on lid covering the shaft, remove the battery lid on the kMeter installed under the shaft and replace the batteries.

The previous model called the kMeter Module operates using a 9 V battery and it needs to be turned on when you want to use it. Push and hold the on button for a few seconds and it will start blinking with a blue light, which will indicate that it’s ready to be connected to your device via the kMeter app. If the on/off button does not blink when pushed or if you can’t connect to the Module from the App, the battery needs to be replaced. This could be done by opening the battery lid on the kMeter Module.
