The reason for stopping recording
All these results are calculated wherever possible. If the file contains any off-
scale records (outside the recording range of the instrument) then some results
may be invalid. A warning is shown if this is the case and some items may be
shown as “unknown”. Off-scale records can be caused by a faulty temperature
probe.
7.4 ERASING A FILE
When files are no longer required you can remove them by selecting the Erase
option from the main menu. The “Menus” section explains the operation of the
menu in detail.
Move the menu highlight to Erase and hold the actuator on the top right (OK)
switch for ten seconds. The display shows you what is happening. All recorded
files are erased together. After the files have been erased you can release the
switch and the instrument will be ready to record again.
When you use the RPU-352, PRU-353with the RPC-80 printer/charger unit you
can erase the files, after they have been printed, by using the control panel of the
RPC-80. Files that have been printed using the RPC-80 must be erased before
you can record any more files.

The limits for this result vary according to the display units selected.
