Start Auto-Cal
Initiates complete calibration cycle with or without auto-span adjustment. The message
"Engage Auto Span?" will appear momentarily and then the prompt "ENTER = Adjust
Span CANCEL = Span Check" will be displayed. If span adjustment is desired, press
and then enter the Level 1, 2, or 3 access code. If span verification only is desired,

adjustment will be disabled and the "Engage Auto Span?" prompt will not appear - span
will be verified only.
System equilibration will occur before and after calibration cycle; both equilibration peri-
ods last for the programmed number of complete cycles (Equil_Cycles). After equilibra-
tion, calibration cycle ∆ƒ measurements will begin and last for the programmed number
of complete cycles (Cal_Cycles). Span value will be verified or adjusted during the
calibration cycle. Display will return to normal operation screen when calibration cycle
is complete.
Start Auto-Zero
External valves used to switch sample or reference gas through external dryer must be
switched manually before using this function. Initiates zero cycle with or without auto-coeffi-
cient D (CD) adjustment. The message "Engage CD Change?" will appear momentarily and then
the prompt "ENTER = Adjust CD CANCEL = CD Check" will be displayed. If CD adjustment
is desired, press

(Zero_Cycles). Offset value will be verified or adjusted during the zero cycle. Display will re-
turn to normal operation screen when zero cycle is complete. External valves must be switched
back to normal operation position when zero cycle is complete.
Flow Moisture Gen
Initiates calibration cycle but does not invoke cycle timers. Operator must allow sufficient time
for readings to stabilize before and after the calibration cycle. When this menu item is selected,
the message "Moist Gen Starting" will be displayed, followed by the message "Wait for Instru-
ment to Stabilize, Then ENTER = Span CANCL = Quit". If
is fully equilibrated, the function will terminate and the message "Operation Aborted" will be
displayed.
When equilibration period has ended, wait for several more cycles before pressing
larly when enhanced noise smoothing is being used. This will allow calibration cycle
surement to stabilize. When

Flags1 list is enabled, the span adjustment will be disabled and the message "No Span Change
(F1)" will be displayed.
