To get out of the test mode press ‘ESC’ at the ‘Enter Test # ?’ prompt. The indicator will now restart in
normal measurement mode and you will see the normal power up sequence.

Clearing the Setup memory
Clearing the Setup memory erases all the transducer calibration coefficients stored in the indicator. It also
erases the whole data memory because once the transducer setup data is modified the stored data will
not correspond to the new transducer calibration coefficients which will be setup.
Later on, when you need to erase only the stored data without erasing the transducer setup data (i.e.
calibration coefficients) you will use the ‘Clear data memory’ function described elsewhere in this section.
To clear the Setup memory, turn off the indicator and while pressing the ‘CH NO’ key turn on power to
the indicator. The display will flash the following messages in succession

REMOVE ALL TXDR?
If you are not sure that you want to proceed or you have erroneously entered this function there is still
time. Press the ‘ESC’ key to exit this function.
If you are sure you want to proceed press the ‘ENTER’ key to confirm your action. The indicator gives
you yet another chance to confirm your action or exit. The display will flash
ARE YOU SURE ?

to indicate that the Setup memory has been successfully cleared. The indicator will then reboot, that is, it
will restart the indicator in the normal mode and you will see the power on sequence.
4.6
Clearing the Data memory
The EDI-53 indicator can store up to 6700 readings in its internal data memory. Before you can reuse this
memory, it is necessary that all memory contents be cleared to accept fresh data. Using the clear data
memory function only erases the readings (i.e., measurement data) stored in the indicator. The
transducer calibration coefficients (or setup information) stored in the setup memory are left untouched.
You do not need to clear the data memory if you have already run the clear setup memory function. The
clear setup memory function automatically clears the data memory also.
To clear the data memory, turn on power to the indicator while keeping the ‘STORE’ key pressed.
Release the key as soon as the ‘—SELF TEST—‘message appears. The display will flash the following
messages in sequence.
