User's Manual Part 3

• Open or intermittent thermocouple, cable, or connector: Individual channels
being detected as “Open” on the profile plot will indicate this. Check thermocouple
wires and insulation. Also, check the connectors visually for damage or loose
connections. Tighten all the connections and check with an ohmmeter or millivolt
meter if available or substitute a thermocouple that you know works properly.
• Shorted thermocouple, cable, or connector: This is harder to find. A shorted
thermocouple connector or cable creates a new thermocouple junction at the
location of the short; therefore, actual temperatures are recorded, but not the ones
desired. If the short is intermittent, the recorded temperatures may jump between
that of the thermocouple and that of the shorted location. Visually check for shorts
inside of connectors and for damaged insulation on the wires. Repair or replace
any suspicious components.
• Wrong type thermocouple, connector, or wire: Wrong thermocouple types will
give consistently wrong readings, either always high or always low. Wrong
connectors or wrong wire types (used as an extension) create extra thermocouple
junctions and uncontrolled temperature offsets. Use only Type K thermocouple
wires, and connectors.
• Thermocouple connector wired backwards: Typically causes high
temperatures to read as negative (e.g., -150°F.). Should be Yellow=Ch, Red=Al.
• Low Power Pack charge: Charge the Power Pack.
• Conductive contamination inside the M.O.L.E. Profiler or I/O Module:
Although unlikely, this is known to cause “spikes” (abrupt jumps in value) in the
recorded temperatures. Other kinds of errors are also possible.
• Incorrect calibration: If the recorded temperatures for all of the active channels
are wrong in the same direction (e.g., all too high), then possibly the M.O.L.E.
Profiler has incorrect calibration. Refer to Calibration Information for cautions and
procedures, or return the M.O.L.E. Profiler to ECD for re-calibration.
• Internal temperature effects: If the M.O.L.E. Profiler and it's components has
been subjected to an internal temperature in excess of the published
specifications. Temperatures outside the specified operating range may cause
incorrect readings and shorten Power Pack battery life. Internal temperatures in
excess of the absolute maximum warranteed internal temperature may
cause permanent, irreparable damage to your M.O.L.E. Profiler.
• M.O.L.E. Profiler never turns on, but the software can read and write the
hardware configuration: The start button is possibly defective, return to ECD for
service.
• SuperM.O.L.E.® Gold LED stays on steady (no flashing) when power pack is
replaced:
1) Try a fully charged Power Pack.
2) For MEGAM.O.L.E.® and SuperM.O.L.E.® Gold try removing the Power Pack
waiting a minute before plugging it in again. If the problem is still there, the start
switch is probably damaged. Contact ECD to request an RMA (Return
Merchandise Authorization) to return the M.O.L.E. Profiler for service. Refer to
Service>How to Get Additional Help for contact information.
