FID: 44750
Span Pt1 (Up/Dn)
Enter=New calib
If more than one reference span gas concentration has been configured,
pressing the Up/Dn keys will allow you to scroll through all defined
reference gas concentration points.
2. To perform the actual SPAN calibration (for example at 100 ppm
isobutylene):
FID-only: Press ENTER
●
PID/FID: Press 1, 2, or 3
●

3. Apply the appropriate span gas to the probe at ambient pressure (using
a clean and labeled gas sampling bag) and then press ENTER.

The instrument analyzes the span sample.
When only one reference span gas concentration is used, the ACCEPTED
message appears for a short time and is then replaced by the normal
CALIBRATION menu.
