Questions answered in Belling manuals
How should the BL0937 be calibrated?
Use a single‑point calibration: apply a rated voltage and current, measure the corresponding CF, CF1 and P pulse frequencies, then compute voltage, current and power conversion coefficients (Ku, Ki, Kp) for use in the system software.
From: Belling BL0937 Smart Socket Metering Chip Application Guide
What does the CF1 pin output?
CF1 provides an active‑power high‑frequency pulse with a fixed 38 µs width; its frequency is proportional to the measured power, and it also indicates over‑current with a 6.78 kHz pulse.
From: Belling BL0937 Smart Socket Metering Chip Application Guide
What supply voltage range does the BL0937 require?
The chip operates with VDD between 3.0 V and 3.6 V.
From: Belling BL0937 Single-Phase Socket Metering Chip Datasheet
How is over‑current indicated by the BL0937?
When an over‑current condition occurs, the CF pin outputs a 6.78 kHz pulse.
