NTG-3000 Operating Instructions Version 2.11

Page 11 of 18

11.2

Scan Rate of the analog inputs

The measured values are read at different rates in the different modes:

Scan Rate

Mode 1

100 µs

2 ms

Mode 2

500 µs

2 ms

Channel

DC1

DC2

DC3

Note:

If the analog input filter is enabled, the advanced phase failure detection (see 12.2) and

the rate-of-change filter (see 12.3) are disabled!
