Techniciancs can use multiple data loggers to monitor several parameters to make troubleshooting and commissioning easier. The updated functions of the Fieldpiece DL3 to include features commpnly requested when designing the Datalogger. Combined with Fieldpiece's accessory head instruments, the Fieldpiece DL3 is the most versatile data logger for HVAC/R field service.

The Fieldpiece DL3 measures any single parameter from any of Fieldpiece's accessory head instruments from once every second to once every 999 hours. For example, if ther user wanted to measure the temperature of a walk-in refrigeration unit, simply use any accessory head that measures temperature through a k-type thermocouple over night, for a few day, or, (although unlikely) once every month and 11.625 days.


A common customer complaint is "The system runs all the time". With multiple Fieldpiece DL3s, the user can determine if the system is indeed running all the time as well as troubleshoot the cause of the problem. Put one Fieldpiece DL3 HVAC/R Data Logger with an ACH4 on the condenser to log amperage to track the time when the system is running and how hard. At the same time, log indoor temperature by using the Fieldpiece DL3 with an ARH4 to see if the target temperature is being reached and if the system is performing as it should.

By downloading the data from two DL3s into a spreadsheet the user can analyze it, line up the times, format the data and perform mathematical operations, and format the graph into a excel spreadsheet.
