Table 11.14 shows the decimal point value based on the decimal no.:
Table 11.14. Decimal Point Values

0 0 None
1 0 FFFFFF.

EXAMPLE: You want BAT DP to be FFF.FFF. This corresponds to 4 Hex. To write this information to RAM of
meter #15, send the command *15P1104. The meter will respond with 15P11.
11.14 Batch Load (“B LOAD”), Batch Scale (“BAT SC”), Rate Offset (“RTE OF”), Rate Scale
(“RTE SC”), Total Offset (“TOT OF”), Total Scale (“TOT SC”)
These 4 items are 3 bytes each (6 characters). All use command prefixes G, P, R, and W. Suffixes are as
follows:
B LOAD and RTE OF =12
BAT SC and RTE SC =13
TOT OF
=15
TOT SC =16
Three bytes equal 24 bits. Bits 0 through 19 are assigned to the value in hexadecimal. Acceptable value from 0
to 999999 for positive numbers and 0 to 99999 for negative numbers.
Bits 20-22 are assigned to the decimal point location according to Table 11.15:

Bit 23 is the sign bit where 0 corresponds to a plus sign and 1 corresponds to a minus sign.
NOTES:
1. The decimal points of B LOAD, RTE OF, and TOT OF are automatically adjusted to be equal to their
corresponding decimal point. For example, if the TOT DP is 3 and the value of 221.42 is entered as the TOT
OF, 221.420 will be stored in memory. If the value is updated to the corresponding system decimal point and
the resultant value is larger than 999999 for positive offsets or 99999 for negative offsets, FFFFF will
automatically be stored in the corresponding memory.
2. Scales and offsets are applied to their corresponding values according to the following formulas:
