For which maximum recording time is the memory module (4 GB) in my Mavowatt laid out, or for how long can I record values with my Mavowatt?
There’s no single answer to this question, because memory capacity requirements depend on device settings and events which occur within the system.
The more quantities are recorded, the smaller the recording intervals are, and the more events are detected in the system, the more memory capacity is required.
In order to nevertheless be able to make a statement regarding memory capacity, we performed numerous measurements with the Mavowatt 70. Various events were simulated while recording was in progress, for example voltage dips and rises.
The results of this measurement series are included below along with the utilized settings, as well as required memory capacity:
Mavowatt 30/40/70 recording time and download speed:
Download via NodeLink: @9600Bd = 45kB/Min, @115200Bd = 180kB/Min
The instruments stop recording after max. 256 MB (default setting: 128 MB), and create a new directory on the CF card. Measured values and characteristic waveforms are first written to RAM, and subsequently to the directory created on the CF card. In this way, uninterrupted recording is assured.
