Frequently asked questions
How do I set the communication address of the meter?
Use the BUS communication settings; the address can be set between 1 and 247.
What do the three LED indicators on the panel mean?
The LEDs indicate Alarm, Phase sequence, and Loss voltage conditions.
Does the DTSF1352 provide a reactive (un‑power) pulse output?
No, the DTSF1352 only has an active pulse output; it does not provide a reactive pulse.
