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).
