FRQ CUT OFF
When below this value of Frequency then FRQ = 0.0
VOL CUT OFF When below this value of volume flow then Vol Flow = 0.0
MASS CUT OFF When below this value of mass flow then Mass Flow = 0.0
TIME BASE Used to calculate flow rate in Kfactors or Total in flow 1, 60 or 3600 based on time
UP DATE TIME 0.02 sec to 9999 secs for update control
FRQ CONSTANT Default 2.0 -7 used to adjust the internal crystal frequency.
VOL FACTOR Multiplier Volume flow rate by this factor (for special applications)
MASS FACTOR Multiplier Mass flow rate by this factor (for changing to pounds 8.32778)
ALPHA Alpha factor used for Stro and Ros calculation.
CAL_TEMP Calibration temperature of sensor used for Stro and Ros.
Sort Curve
Through out the system each curve can be sorted or left as entered. Each curve works from lowest entry to
highest entry, if entered this way then the sort routine does not need to be used. If you add a point that is not
the highest then use the sort curve function.
Reset Totals
This option allows the user to clear totals, please note that there maybe more than one total, i.e. Volume and
Mass totals, each needs to be cleared! Use the ALTER key when on a RESET VOL 0=Y option to scan for the
next total.
