28. Replacing the EPROM
The EPROM may be easily replaced by a new unit when faulty or update the software.
The EPROM - replacement procedure is as follows:
P Disconnect the analyzer from the source of electric power.
P Open the housing (see
chapter 23.).
P Remove jumper J7 (for the battery buffering; see the chapter 19.).
P Pull out the EPROM (chapter 18.).
Align the EPROM with respect to the socket before re-insertion.
EPROM
mark
The EPROM is aligned correctly if the mark points to the front panel.
P Insert the EPROM.
P Reconnect jumper J7 (see the chapter 19.).
P Reconnect the instrument to the source of electric power and switch it on
[see chapter 6. (the displays must show a flashing "batt.")].
All stored data have now been replaced by default values.
All user and application data, such as system parameters, threshold values etc., must be
re-entered.
A complete re-calibration of the instrument (see chapter 9.) must be
performed after an EPROM replacement.
