0=off, 1=type 1 input, 2=type 2 input, 3=type 1 test mode, 4=type 2 test
mode
Type 1, counts are inversely proportional to process variable
Type 2, counts directly proportional to process variable
Shows countdown for timed calibrations
Base address of temp. comp. channel block
Base address of tach or flow channel block
Counts per second from counter
Location 6 multiplied by location 29
Source decay comp. using decay factor at location 27
Compensation per current standardize counts at location 25
Counts input converted to 0–10,000 count range
Linearized and converted to process units, e.g., SGU, lbs/ft, etc
Filtered per time constant in product code table
Compensated to reference temperature using process temperature and
temperature coefficient
Final customer process units for display
For slurries only, 0 for all others
Weight per unit time when tach/flow channel enabled
(Product Multiplier/Divider)—On slurries (type 2 density measurements)
used as a scale factor for DRY SOLIDS. Used as scale factor to get
FINAL PRODUCT on all other applications
Scaling for rate customer units
Scaling for rate customer units
For temperature compensation
Standardize compensated counts where measurement cuts off
XXXXX seconds for cutoff filtering
1 if measurement is cut off, 0 if not
From last standardize—standardize gain=location 26/location 25
Starting counts from original calibration
Decay gain=65536/65536—decay factor
Source type code for decay rate
Entry=gain factor for location 7
Enter 0 to 9 for selected function code
Enter 1 to Start a selected function. Enter second 1 to Stop function in
Start/Stop mode. Location zeroes automatically
