Irradiance
During the ten minute warm up period, the radiant heater is at 100% power (~27 mW/cm
2
). After the radiant heater
has been running in warm up mode for ten minutes, the heater power setting drops to 25% (less than 10 mW/cm
2
).
Note: The 25% setting can be changed in Service Mode.
Weight Scale Performance
Functional Range 300g - 8 kg
± 10gAccuracy
Resolution 10g (Factory setting) or 5g (user selectable on non-EU scales)
The resolution of scales distributed in the EU region vary depending on the
scale revision:
• Scales with revision 2.72 only have a resolution option of 10g.
• Scales with revision 2.86 have a resolution of 5g for weights up to 5 kg and
a resolution 10g for weights from 5 kg to 8 kg.
• The resolution on EU scales with software 2.86 and above is not user
selectable.
Note: For the European Union (EU) and the European Free Trade Association (EFTA) member states in Europe, check
with your local regulations with respect to the Non-Automated Weighing Instrument (NAWI) directive as to the
process and frequency for scale calibration. The resolution of scales distributed in this EU region only have a
resolution option of 10g.
Servo Oxygen
The time from turning on the servo control oxygen system until the system is fully operational is less than 10 seconds.
Control Range 21% - 65%
Resolution 1%
Accuracy* 5% (< 0.02% drift over 24 hours)
Rise Time ≤ 10 minutes from 21% to 5% below set point (in Whisper Quiet™ mode)
Recovery from Opening Porthole ≤ 5 minutes from closing porthole to 5% below set point (in Whisper Quiet™
mode)
Inlet Pressure 310 kPa (45 psi) - 620 kPa (90 psi)
Effects of Barometric Pressure: The Servo O2 system is not equipped with
automatic barometric pressure compensation.
Between Servo O2 system calibrations, a 1 kPa barometric pressure increase
will increase the oxygen concentration reading by 0.2% O
