Service and Troubleshooting

This section covers maintaining and troubleshooting hardware, sensors, M.O.L.E. Profiler Power Pack, Software, Wiring, and other parts of the system.


The following service and calibration instructions are for use by qualified personnel only. Refer to the Safety>Operators Safety Information prior to performing any service.

Service Troubleshooting:

Decide if the problem is with the Hardware, Communications, or Software.

If the problem occurs while attempting to log data, the Hardware may be faulty.

If the problem occurs while attempting to communicate between M.O.L.E. Profiler and the computer, the Communications links may be faulty.

If the problem occurs while attempting to use a software function, the software may be faulty.

Once it has been determined what item is causing the problem, refer to the appropriate service section. Start at the top of the list and work your way down.

Hardware Problems:

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.

SuperM.O.L.E.® Gold 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)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 the Service and Troubleshooting>How to Get Additional Help topic for your M.O.L.E. Profiler for contact information.

The SuperM.O.L.E.® Gold Profiler clock resets itself: Calendar/clock battery discharged: Replace the calendar/clock battery.

MEGAM.O.L.E.® 20, V-M.O.L.E.®, or SuperM.O.L.E.® Gold 2 becomes unresponsive:

1)Battery low condition: If the user attempts to turn the M.O.L.E. Profiler ON and it does not respond, charge the Power Pack. Refer to topic Setup>Charging the Power Pack for your specific M.O.L.E. Profiler.

2)Manual Reset: Sometimes when the Power Pack has been depleted, it can cause the M.O.L.E. Profiler to appear ON but unresponsive when pressing any of the buttons. To Manually Reset, PRESS and HOLD the OK button for more than a full 12 seconds.


MEGAM.O.L.E.® 20, V-M.O.L.E.®, or SuperM.O.L.E.® Gold 2 has blinking or erratic Activity Indicator lights: This condition could occur when the Power Pack has been depleted. Charge the Power Pack. Refer to topic Setup>Charging the Power Pack for your specific M.O.L.E. Profiler.
