Item# Parameter Name Parameter Description
0 SIGNAL TYPE 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
1 Status Location Shows countdown for timed calibrations
2 SPARE LOCATION
3 SPARE LOCATION
4 TEMPERATURE
COMPENSATION
CHANNEL POINTER Base address of temp. comp. channel block
5
TACH/FLOWMETER
CHANNEL POINTER Base address of tach or flow channel block
6 RAW COUNTS Counts per second from counter
7 AMPLIFIED RAW COUNTS Location 6 multiplied by location 29
8 DECAY COMPENSATED
COUNTS Source decay comp. using decay factor at location 27
9 STANDARDIZE
COMPENSATED COUNTS Compensation per current standardize counts at location 25
10 NORMALIZED COUNTS Counts input converted to 0–10,000 count range
11 PRODUCT Linearized and converted to process units, e.g., SGU, lbs/ft, etc
12 FILTERED PRODUCT Filtered per time constant in product code table
13 TEMPERATURE
COMPENSATED
PRODUCT Compensated to reference temperature using process temperature and
temperature coefficient
14 FINAL PRODUCT Final customer process units for display
15 DRY SOLIDS For slurries only, 0 for all others
16 RATE Weight per unit time when tach/flow channel enabled
17 PRODUCT MULTIPLIER
18 PRODUCT DIVIDER (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
19 RATE MULTIPLIER Scaling for rate customer units
20 RATE DIVIDER Scaling for rate customer units
21 REFERENCE
TEMPERATUREX For temperature compensation
22 MEASUREMENT CUTOFF
SETPOINT Standardize compensated counts where measurement cuts off
23 CUTOFF TIME CONSTANT XXXXX seconds for cutoff filtering
24 CUTOFF FLAG 1 if measurement is cut off, 0 if not
25 STANDARDIZE AVERAGE
COUNTS From last standardize—standardize gain=location 26/location 25
26 CAL. LOW AVG. COUNTS Starting counts from original calibration
27 DECAY FACTOR Decay gain=65536/65536—decay factor
28 DECAY REFERENCE Source type code for decay rate
29 RAW GAIN Entry=gain factor for location 7

FUNCTION CODE Enter 0 to 9 for selected function code
31 START/[STOP] Enter 1 to Start a selected function. Enter second 1 to Stop function in
Start/Stop mode. Location zeroes automatically
