Press ‘ENTER’ key to confirm or press ‘ESC’ key to cancel the operation. Display will revert back to the
channel number prompt and show the same channel number by default.
CAUTION !
Before erasing any individual transducer you should make sure that there is no data for that transducer in
the data memory. Otherwise if there is any earlier data of that particular transducer present in the data
memory it will get corrupted. It is strongly recommended that you should printout the data in the data
memory or transfer the data memory contents to a host computer before erasing any individual
transducer. After that first erase the data memory and then erase the individual transducers from the
setup memory.

Erasing setup data for all channels
If you want to erase the setup data for all the channels for any reason it is much easier to use the
procedure described in ‘Clearing the setup memory’ described earlier in the section ‘Operation’.
Generally you need to erase the whole setup memory either while you are about to program the setup
memory for the first time or you are shifting the indicator to a new site or project.
You will also need to clear the whole setup memory if the internal Non-Volatile RAM memory (NVRAM)
module becomes defective and has been replaced.
The whole setup memory should be cleared if for some reason you find that a part of the setup data has
become corrupted (generally this is due to some hardware fault). If such a thing has happened then it is
better to completely clear (erase) the whole setup memory and reprogram it to avoid the possibility of
undetected errors remaining in the setup data.
In view of the above discussion it is advised you should always keep a printout of the ‘Setup data’ after
you have completely programmed the setup memory or after you have made any modifications to setup
data.
