Logging Functions (models with datalogger option only)

NOTICE
This chapter only applies to GF U3000 V2 (HM) models with datalogger option.
This is procedure shows you how to set up a basic logging session under manual start/stop control. Logged data is saved to the
instrument's memory and can be copied to a USB flash drive as a CSV (Comma Separated Values) file at a later time. Date, Time,
Flow Rate, Forward (+) and Reverse (-) totals, Velocity, Signal Q(quality), SNR and general signal status are logged automatically. If
the unit has a Heat meter fitted, the Hot, Cold and the Temperature difference values are logged in addition to instantaneous pow-
er, and a total energy figure. Logging writes to internal memory, which may then be copied to a USB flash drive at a later date.
5.4.1 Manual logging
