Professional FAQ
How long does setup take for first use?
Most users finish mapping all channels in under 20 minutes.
Can it run near high-power inverters?
Yes, but keep sensor cables away from motor lines to cut noise.
What issue appears most in the field?
Wrong wiring mode (2/3/4 wire) is the most common cause of drift.
How can I reduce signal jump?
Use tight shield grounding and slow the filter time.
Will it work in long-run cable jobs?
Yes, shielded cable up to 200 m is supported if grounded well.
