4.5 Measurement Data Recording (METRAHIT⏐X-TRA⏐OUTDOOR only)
The METRAHIT⏐X-
TRA⏐OUTDOOR is capable of recording measure-
ment data using an adjustable sampling rate for long periods of
time in the form of measurement series. Data are stored to a bat-
tery backed memory module, and are retained even after the mul-
timeter is switched off. The system acquires measured values rel-
ative to real-time.
Stored measured values can subsequently be read out with the
help of METRAwin 10 software. The only prerequisite is a PC which
is connected by means of an interface cable to the
USB X-TRA bi-directional interface adapter, which is in turn
plugged onto the METRAHIT⏐X-
TRA⏐OUTDOOR. See also chapter 7.
