STORING A DRAUGHT MEASUREMENT TO PRINT WITH A
COMBUSTION TEST
Rather than print a draught test report and then a combustion test report it is possible to
combine the two sets of results on one printout by taking a draught reading first and storing it
for printing later.
The following sequence must be followed:
With PRESSURE on the top line and with the rotary dial pointing to Prs... and with the pump
off..... then if LOG is activated the current pressure reading will be stored in the draught
register with its current scaling. All the conditions must be met and no other values will be
logged. As this occurs the top line display briefly shows "DRAUGHT".
While the instrument is in this mode activating LOG again will overwrite the stored reading.
The stored reading is cleared whenever the analyzer is switched off or by entering any
REPORT menu.
Resuming normal operation adds the stored DRAUGHT reading to any combustion printout
or any combustion log. In such cases the printout changes so instead of "PRS" being printed
"DRGT" is printed instead.
NOTE: Whenever there is a stored DRAUGHT reading the current pressure reading is
ignored and the stored reading is always used.
WARNING: This means that if a user stores a draught reading from one appliance and goes
to another appliance without switching off or re-entering the reports menu his printouts and
logs will show the last stored draught reading and its scaling.
