Sampling Type (dCF05 & dCF06)

Three types of data sampling are available: average, snapshot and USDA. When configured to average, the aver-

age of readings taken every minute over the recording period is recorded. When configured to snapshot, the sen-

sor reading at the log interval time is recorded. When USDA is configured, the supply and return temperature

readings are averaged and the three USDA probe readings are snapshot.

4.7.7

The 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 their

DataCORDER configured for USDA recording, but do not install the probes for every trip. If all the probes are dis-

connected, 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.

4.7.8

The DataCORDER may be powered up in any one of four ways:

1. Normal AC power: The DataCORDER is powered up when the unit is turned on via the stop-start switch.

2. Controller DC battery pack power: If a battery pack is installed, the DataCORDER will power up for commu-

nication when an interrogation cable is plugged into an interrogation receptacle.

3. External DC battery pack power: A 12 volt battery pack may also be plugged into the back of the interrogation

cable, which is then plugged into an interrogation port. No controller battery pack is required with this method.

4. Real Time Clock demand: If the DataCORDER is equipped with a charged battery pack and AC power is not

present, the DataCORDER will power up when the real time clock indicates that a data recording should

take place. When the DataCORDER is finished recording, it will power down.
