4.6.4 Logging Interval (dCF03)
The user may configure four time intervals between data recordings. Data is logged at exact intervals in accor-
dance with the real-time clock. The clock is factory set at Greenwich Mean Time.
4.6.5 Thermistor Format (dCF04)
The user may configure the format in which the thermistor readings are recorded. The low resolution is a 1 byte for-
mat and the normal resolution is a 2 byte format. The low resolution requires less memory and records temperature
in 0.25

C (0.45

F) increments when in perishable mode or 0.5

C (0.9

F) increments when in the frozen mode. The
normal resolution records temperature in 0.01

C (0.02

F) increments for the entire range.
