The OMP-MODL may have a corrupted Program Net:
Perform a system intialization with the following procedure:
A.Depress and hold the NEXT button down on the front panel.
B.Momentarily, depress the STOP and RESET buttons simultaneously, then release them.
C.After a second or so, release the NEXT button.

Power Failure / Batteries drain with External Power Source Connected:
The external power fuse may be blown. This would prevent the logger from running from the external power source and it would continue running from the batteries until they discharged. Refer to Appendix D for the location of this fuse. The fuse can be checked with a continuity meter and should read less than 1 ohm of resistance. If it is open, replace it with a 1.5A, Littelfuse P/N: 273.015 available from Omega Engineering Incorporated or an electronic components distributor.
