When you have saved a lot of readings and only 50 or so memory locations are left for storing data you
will see a message like the example shown below after the ‘data saved’ message
Memory LOW! 35
This message informs you that there are only 35 more free memory locations for storing data. If you need
to store more number of readings you should first print out the current ‘log data’ or down load the ‘log
data’ to a computer, use the ‘Clear data memory’ function to erase the data memory and then store
further data.
Once the data memory gets full and there is no free memory location left to store any further reading, you
will get the following message
Err: MEMORY FULL
If you press the ‘STORE’ key while in any mode other than the ‘units mode’ the display will flash an error
message
GO TO UNITS MODE
Select the units mode by pressing the ‘UNITS’ key and then save the reading.

Recalling stored readings
If you have stored any readings in the indicator data memory you can recall the readings later on at any
time.
The indicator groups the stored readings according to channel number, irrespective of in which order they
were stored. Also, the readings are arranged chronologically in memory, i.e. the earliest reading is stored
first and the latest reading stored last.
However, it may be noted that if due to some oversight you store some readings and then set the clock at
an earlier date and time, subsequent readings will be stored at the end of the data memory. While
recalling or printing the stored readings you will be surprised to find data with an earlier date stamp
occurring after later data.
To recall a stored reading, you have to tell the indicator for which channel number (i.e. transducer) you
want to recall the data. Press the ‘RECALL’ key. Display will flash
* RECALL *
then prompt
Ch # ? 0_
Enter the channel number whose data you want to recall. Assuming you select channel number 4.
Display will show the last saved reading for this channel
R004: 1.05 kPa
The ‘R’ in symbol ‘R004:’ indicates that you are seeing recalled data (i.e. the indicator is not measuring
anything) and 004 shows that you are looking at stored data of channel number 4. The stored value of
the parameter follows.
If you need to find the date and time the reading was stored simply press the ‘DATE’ or ‘TIME’ key to see
the date or time.
If you have stored a number of readings for a particular channel you can scroll through the data by using
the ‘PREV’ and ‘NEXT’ key. Pressing the ‘PREV’ key shows the earlier stored data for this channel.
Pressing the ‘NEXT’ key shows the next stored data for this channel. While pressing the ‘PREV’ or
‘NEXT’ key you reach the end of table, i.e. there is no more data to show, the display will prompt
