How long can I record values in the MAVOWATT 30,40,70?
Memory capacity requirements depend on device settings & system events. 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.
Here are some measurements taken with the Mavowatt 70. Various events were simulated while recording was in progress, for example voltage dips and rises.
With continuous recording at 10 second intervals (without events) including harmonics: Approx. 2 MB per hour: 256 MB = 128 hours = 5 days, 8 hours
With continuous recording at 1 second intervals (without events or harmonics):
Approx. 5 MB per hour: 256 MB = 50 hours = 2 days
With continuous recording at 10 minute intervals (without events) including harmonics:
Approx. 320 days. Approx. 50 kB per event with default settings (2 x 5 periods, waveform and 2 x 12 rms)
Download via NodeLink: 9600 baud = 45 kB per min., 115,200 baud = 180 kB per 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.
