4-4 5000 Multi Point Moisture Analyzer
The variable Cal_Timer should not be confused with the variable Cal_Time described in Chap-
ter 3: Test/Config Key, Set Auto_Cal Time. If verification needs to be run once a day at the same
time, Cal_Time should be set to the time of day for these cycles to occur; Cal_Timer should be set
to 000000. If verification is required more frequently, set Cal_Time to 00:00 and Cal_Timer to the
interval in seconds between cycles.
Moist_Gen

This value should not be changed unless a special unit conversion, such as ppmv to lbs/mmcf, is re-
quired or if the moisture generator is replaced. Enter new moisture generator value when the "New
Value?" prompt is displayed. Press
ENTER to save change and return to the Configure Menu; press
CANCEL to quit.

Flags1 (Configuration Flags)
The following list of software configuration features can be selected or deselected by altering the
value of Flags_1. The Flags_1 value is essentially a set of positions for eight bits, or one byte, of com-
puter logic. Each bit position has a specific binary value when turned ON; all bits have a value of
zero when turned OFF. The value entered for Flags1 is the sum of bit values for all of the features
to be selected. Enter the new flag value when the "New Value?" prompt is displayed. Press
ENTER to
save change and return to the Configure Menu; press
