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.
