3.6.4 Logging Interval (dCF03)
The user may select four different time intervals
between data recordings. Data is logged at exact
intervals in accordance with the real time clock. The
clock is factory set at Greenwich Mean Time (GMT).
3.6.5 Thermistor Format (dCF04)
The user may configure the format in which the
thermistor readings are recorded. The short resolution
is a 1 byte format and the long resolution is a 2 byte
format. The short requires less memory and records
temperature with variable resolutions depending on
temperature range. The long records temperature in
0.01C (0.02F) steps for the entire range.
