There's actually a gap between the chip and piggyback bonded assembly you can slip a piece of paper between, the packages and electrical connections are only attached to each other at the opposite ends where there are two leads for the crystal and two leads for the battery, both of which are enclosed by and potted into the rectangular module above. These DIP-28 package chips are actually just a realtime clock and SRAM lower chip with a crystal and battery bonded to the top of the lower chip with wires encapsulated in the epoxy bonding. The error is caused by the "10 year" Li-ion battery inside the chip going bad - after 10 years - and the MK48T08B is no longer manufactured. These units were built with Dallas Semiconductor or ST Microsystems MK48T08B real time clock/sram/crystal/battery chip. This repair guide is for fixing the "Error 6" (corrupted memory) message in a fluke Hydra datalogger.
