Manual Calibration
Whether you are calibrating a single range or multiple ranges, each range requires its own
complete zero and span calibration.
If you are calibrating multiple ranges during one session,
the zero calibrations can all be performed before any of the span calibrations, as long as they are
within the same relatively short time period. If multiple ranges are used, the calibrations are
typically done in ascending order of range. Anytime a zero calibration is performed, a span
calibration or check should be done afterward.
The analyzer has two separate manual calibration menus, one for THC or CH
4
mode and a
second menu for THC/CH
4
/NMHC mode. The analyzer automatically chooses the menu
depending on the mode it is in at the time it enters the Manual Calibration menu.
In THC or CH
4
mode, the analyzer has basic zero and span calibration capability in either THC
or CH
4
mode. In THC/CH
4
/NMHC mode the analyzer has basic zero and span capability in THC
mode and also includes the added CH
4
Correction Factor feature. See
details.
