Function Descriptions

Two-decimal-place Mode
If pin 2 on the DIP switch is turned ON, values are stored to two decimal places. In this case, tempera-
ture 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.
Additional Information
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°C
(°F). Treat any resolution above that specified for the normal data format as reference data.
