SECTION 8. PROCESSING AND PROGRAM CONTROL EXAMPLES
8-12
Table 8.10-3 lists the input channel
configuration and Input Storage allocation for
the measured values. After reading the new
input samples, the Level 2 measurements are
relocated using the Block Move Instruction 54,
then Ta1 is relocated through a separate move
and e1 is positioned by specifying the
destination location in the Wet/Dry-Bulb
Instruction. The COV/CORR Instruction must
be entered twice, once for each level.
In addition to ordering Level 1 and Level 2 in
locations 1-5 and 11-15 respectively, 2 more
locations are required. Converting the wet-/dry-
bulb measurements to vapor pressure using
Instruction 57 requires atmospheric pressure.
We'll use the standard atmosphere for the site
elevation and key the value into Location 17
using the C command in the
∗6 Mode.
This example requires that 54 locations be
allotted to Input Storage and 79 to Intermediate
Storage (35 for the 1st COV/CORR Instruction,
43 for the second, and 1 for Instruction 92).
