4.4.3 Select Cal Memory
This function allows the user to select one of eight
different memories for gas calibration and measurement.
For Memories #1-7, the calibration and measurement gas is
the same and no correction factor is applied. For Memory
#0, the calibration gas is always isobutylene and the
measurement gas may be different, in which case the
correction factor for that gas is automatically applied. The
default gas selections are listed in Section 4.4
1. “Select Cal Memory?” is the third sub-menu item in the
Calibration sub-menu. Pressing the [Y/+] key, the
display will show “Gas =” gas name followed by “Mem
# x?”
2. Press [N/-] to scroll through all the memory numbers
and the gas selections respectively. Press [Y/+] to
accept the displayed Cal Memory number.
3. After the [Y/+] key is pressed, the display shows
“Save?” Press [Y/+] key to save and proceed. Press
[N/-] to discard the entry and advance to the next sub-
menu.

not calibrated, the display shows “CF= x.xx”. A
correction factor with the value “x.xx” will be applied.
5. If the gas of a newly selected cal memory number has
been calibrated previously, the display shows “Last
calibrated xx/xx/xx”.
