If pin 2 on the DIP switch is turned ON, values are stored to two decimal
places. In this case, temperature data is stored as 6-digit signed hexadecimal
(binary) data with 4 digits in the integer portion and 2 digits after the decimal
point. The actual data stored in memory is 100 times the actual value, i.e., the
decimal point is not indicated. Methods for handling this data are described in
this section.
Note When set to store values to two decimal places, temperature data as far as
two digits after the decimal point is converted to 6-digit binary data, but the
actual resolution is not 0.01°C (°F). For this reason, there may be skipping
and inaccuracies in the first digit after the decimal point (0.1). Treat any reso-
lution above that specified for the normal data format as reference data.
