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).
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 0.01°C (0.02°F) steps for
the entire range.
Sampling Type (dCF05 & dCF06)
Three types of data sampling are available: average, snapshot and USDA. When configured to average, the
average of readings taken every minute over the recording period is recorded. When configured to snapshot, the
sensor reading at the log interval time is recorded. When USDA is configured, supply and return temperature
readings are averaged and the three USDA probe readings are snapshot.
Alarm Configuration (dCF07 - dCF10)
USDA and cargo probe alarms may be configured to OFF, ON or AUTO.
If a probe alarm is configured to OFF, the alarm for this probe is always disabled.
If a probe alarm is configured to ON, the associated alarm is always enabled.
If the probes are configured to AUTO, they act as a group. This function is designed to assist users who keep the
DataCORDER configured for USDA recording, but do not install the probes for every trip. If all the probes are
disconnected, no alarms are activated. As soon as one of the probes is installed, all of the alarms are enabled and
the remaining probes that are not installed will give active alarm indications.

DataCORDER Operational Software

The DataCORDER operational software reads and interprets inputs for use by the configuration software. The
inputs are labeled function codes. Controller functions (see
the current input data or stored data.
To access DataCORDER function codes, do the following:
1. Press the ALT. MODE and CODE SELECT keys.
2. Press an Arrow key until the left window displays the desired code number. The right window will display the
value of this item for five seconds before returning to the normal display mode.
3. If a longer display time is desired, press the ENTER key to extend the display time to 30 seconds.
4. If a function is not applicable for the unit, dashes "-----" are shown on the display for that code.
