The altimeter on Garmin watches relies on barometric pressure to measure elevation. For accurate altitude readings, the altimeter must be calibrated, especially when weather conditions change or after significant altitude changes.

There are two primary ways to calibrate the altimeter:

  • Manual Calibration:

Input a known elevation value based on your current location, such as from a topographic map or a reliable GPS reading.

  • Automatic Calibration:

Some Garmin watches can automatically calibrate the altimeter when connected to GPS, as the device cross-checks GPS elevation data with barometric pressure.

To manually calibrate the altimeter:

  • Open the altimeter settings on your Garmin watch.
  • Choose the manual calibration option.
  • Enter the current elevation value.
  • Confirm and save the calibration.

Automatic calibration is recommended when available, but manual calibration ensures accuracy in areas where GPS signals may be weak or inconsistent.

Calibrating the Heart Rate Sensor

While Garmin watches with optical heart rate sensors do not require traditional calibration, ensuring accurate heart rate data depends on proper fit and sensor placement. For best results:

  • Wear the watch snugly, about one finger’s width above the wrist bone.
  • Keep the sensor clean and free from debris.
  • Avoid loose or shifting placement during workouts.

If your Garmin watch supports external heart rate monitors (such as chest straps), pairing and calibration may involve syncing the device and performing a warm-up session to stabilize readings.

Calibrating the Step Counter and Activity Tracking

Garmin watches use accelerometer data to count steps and track activity. Although there is no direct manual calibration for the step counter, accuracy improves by:

  • Wearing the watch on the wrist you use most frequently.
  • Setting your user profile accurately with height, weight, age, and gender.
  • Performing a few test walks to allow the device to learn your movement patterns.

Some models allow resetting the step count or recalibrating activity data through a factory reset or software update.
