5. Once a correction factor has been selected and
stored for each of the four operating modes,
the unit will proceed into operation using the
programmed coefficients of the storage field
that was selected. Once again, use of
“
FLD A
”
or
“
FLD B
” will be indicated by the field letter
chosen being displayed at the upper right of the
LCD throughout the operating cycle. The
selected storage field will remain as the start-
up default setting unless changed by the user.
6. To return to the factory calibration setting,
“
FAC
”, press and hold the range selector
button while simultaneously switching the
instrument on. Select the “
FAC
” setting by
depressing the handle hold switch. The factory
calibration has just been restored as the default
operating setting. Stored coefficients in “
FLD
A
” and “
FLD B
” will remain for future use.
NOTES:
• Always use the factory calibration setting,
“
FAC
”, in determining the correction factors.
• Correction factors must be in the range of
0.250 to 1.999 (0250 to 1999 without the
decimal point).
• Use of correction factors greater than 1.000
may cause the display to indicate a flow value
at zero flow (typically 12-13 CFM at zero flow).
This is normal and will limit the use of
correction factors at the extreme low-end of the
operating range.
• Do not use measurements which are less than
10 CFM * correction factor. For example, if you
program a correction factor of 1.5, do not use
measurements less than 15 CFM (10 * 1.5 =
15).
