1Based on a single marker stepped through more than 900 positions throughout the measurement volume using the mean of 30 samples at each position at 20°C. 2 Accuracy stated based on overall volume. 3 Varies according to tool combinations with a maximum rate of 60 Hz. 4 If the Host USB Convertor (HUC) is located within the patient vicinity where it may be touched by the patient, the operating ambient temperature range is +10°C to +30°C. If the HUC is located outside this patient vicinity, the operating ambient temperature range permitted for the system is +10°C to +40°C. The power supply unit must be located outside the patient vicinity under all operating conditions.

Measurement Volume

The measurement volume is the region in which tools can be tracked.
