Measurement Data Recording - Gossen MetraWatt METRAHIT EXTRA Operating Instructions Manual

4.5 Measurement Data Recording (METRAHIT E
The METRAHIT E is capable of recording measurement data
XTRA
using an adjustable sampling rate for long periods of time in the
form of measurement series. Data are stored to a battery backed
memory module, and are retained even after the multimeter is
switched off. The system acquires measured values relative 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 E
Operation".
