PERFORMING A TEST
This test only functions if the symbol is displayed. Apply pressure
to system until changes to (Test Pressure). If a (pre-
stress) pressure has been entered the system must be pressurised
to this level. Bleed system. The display will then clear until test time
has elapsed. or will appear on the display and be
automatically logged with test conditions. This logged reading can
be replayed on screen by pressing and keys or output to an
Epson compatible printer by pressing and keys. It cannot be
output to a PC other than via Hyper Terminal. Consecutive records
will overwrite each other so must be output to printer before
performing another test. After showing the the display
will immediately revert to current pressure. The instrument must be
reset manually for each new test.

USER DEFINED SCALE
Press key and will appear before the display clears.
Enter scale percentage. Only the first two digits entered are valid -
this gives a scaling from 1 - 99%. This value will be multiplied into
current display to give user defined scale. Press to accept.
