QTFM2 Sensor Profile Configuration

This feature requires firmware version V1_38 or later. It allows you to load a complete, factory-tested setup with a single command. If you need to update your firmware, see the Firmware Update Guide.

Downloads & prerequisites

Download the latest Windows installer (.exe) referenced in the user guide: Download latest Windows installer (.exe)

If you haven’t installed the Original UI yet (to install required drivers), do that first: Original UI installer (for drivers)

Cutoff[Hz] Bug: Sending a profile sets the correct cutoff filter, but the UI always displays 1 Hz. A fix is being developed.

What is a Configuration Profile?

A profile is a single ASCII command like ~Vector_Survey_Pro~ that instantly loads a complete set of settings onto your sensor.

  • Speed: Faster than setting each of the 20+ parameters individually.
  • Reliability: Prevents errors from sending multiple commands.
  • Consistency: Ensures repeatable, high‑quality data.

Note:  All survey and base station profiles automatically enable ‘Auto-Start’ mode. The sensor will begin measurements immediately after the profile is applied and reboots. The only exception is the ~Stop~ utility command.

How to Apply a Profile

You can send a profile command using any serial terminal program (e.g., the QuSpin UI, PuTTY, Tera Term). The sensor will apply all settings and then automatically reboot.

  1. Find the profile name from the tables below.
  2. Copy the full string (including ~) or click the copy button.
  3. Send the complete string to the sensor.

In the QuSpin UI, paste the profile into Send String and press Enter or click Send String. The terminal confirms the profile, sets the baud rate, and reboots.
  1. Confirmation message in the terminal.
  2. Send String field where you paste the profile.
  3. Location of cutoff[Hz]. This does not visually update when you send a configuration profile.

Important Formatting: Send the full string as one command. Do not add \n or \r.
