Frequently asked questions
How do I power on the controller?
Connect the unit to the correct AC supply (115 VAC or 230 VAC, 50/60 Hz); it will perform a self‑check and start automatically.
How can I calibrate the dissolved‑oxygen probe?
Enter calibration mode via the [CAL/VIEW] key; you can perform single‑point or two‑point calibration, and the values are stored in EEPROM.
What is the maximum load for the relay outputs?
The relays can drive up to 5 A at 115 VAC or 2.5 A at 230 VAC.
