Signal Calibration

When you install FourJaw on your machines, we carry out a process called signal calibration to ensure your machine data is accurate and reliable.

What is Signal Calibration?

FourJaw uses current clamp sensors installed inside your machine’s electrical cabinet. These sensors measure the electrical current (amps) your machine consumes over time, creating a data trace.

Signal calibration is the process of tuning our algorithm to interpret this electrical data and correctly determine:

  • When your machine is running (uptime)
  • When your machine is stopped (downtime)

This step is essential to ensure the insights you see in FourJaw reflect your machine’s real activity. Below is an example of a typical signal calibration.

How the Process Works

  • Sensors are installed on your machine to capture electrical data
  • The data is analysed to understand machine behaviour patterns
  • Our specialists configure and fine-tune the system to accurately classify uptime and downtime

Who Performs the Calibration?

A FourJaw specialist will handle the calibration for you:

  • Remote installs (self-install): Calibration is completed remotely after setup
  • Kickstart installs: Calibration is carried out on-site during your visit

There’s nothing you need to do during this process.

When Will My Data Be Ready?

Signal calibration typically takes 1–2 days after installation.

During this time:

  • Your machine data may not appear correctly straight away
  • This is expected while we fine-tune the system

Once calibration is complete, your machine monitoring will be accurate and ready to use.
