Maximum probe temperature

The table below indicates the maximum probe temperature.

NOTE: Measurement uncertainty and probe variation: 2.0 °C.

NOTE: The probe will stop scanning, if exceeding an applied part

surface temperature of 43°C

NOTE: Lens temperature is measured under conditions per IEC

60601-2-37, Ed2.1

• Thermocouple was placed at the geometric center of the

lens.

• Thermal phantom at not less than 33°C or in the range

20-33°C for external probes. Maximum Vscan Air CL

temperature rise is measured and added to 33°C. Maximum

Vscan Air CL temperature (Simulated use) is <43°C.

• With Vscan Air CL transmitting in air, temperature rise is

measured and added to 23°C. Maximum Vscan Air CL

temperature (Still air) is <50°C. Lens temperature is

monitored for 30 minutes.

NOTE: Vscan Air CL placed in contact with a thermal phantom

made of tissue-mimicking material is referenced in

IEC60601-2-37, Ed2.1

• Auto-freeze capability is disabled during these

measurments.
