MEGAM.O.L.E.® Help System Guide ♦362♦
Environmental Limitation Specifications:
MegaMOLE Profiler:
• Maximum relative humidity 80% RH from 0°C to 31°C, decreasing linearly to 17% RH at 50°C.
• Pollution Degree 2 (Normally only dry pollution, but with temporary conductivity caused by condensation)
Power Pack Charger:
• Temperature: (Operation) 0 to +45°C (32 to 113°F)
• Temperature: (Non-Operation) -20 to +75°C (-4 to 167°F)
• Humidity: (Operation) 20 to 90%
NOTE:Tests have shown that because of the sensitive nature of the measurement and logic circuits, the
following precautions must be observed:
• Minimize exposure to ESD Events. If the M.O.L.E. profiler or one of the thermocouples receives an
8kV electrostatic discharge during the data collection sequence, the M.O.L.E. profiler may switch itself
“OFF”. To retrieve the data, simply upload the data that was recorded prior to the event. If a new data
collection sequence is started without uploading first, the existing data stored in the M.O.L.E. profiler will
be lost.
• Keep strong electromagnetic fields away. The thermocouple wires serve as an antenna for
electromagnetic radiation. If field strength of 3 volts per meter is present (usually due to close proximity
of radio transmitters) while the M.O.L.E. profiler is collecting data, the accuracy of the data may be
compromised. This interference is compounded by using long thermocouple wires, as well as the effect
of the thermocouple wires acting as a “tuned” antenna.
