Note 1: The output values may vary depending on the

accuracy of engagement at the clamp connection.

Note 2: The sensor is detachable up to 100 times (approx.).

Note 3: The sensor’s mechanical construction may cause it

to generate resonance sound. However, it does not affect

the performance of the sensor.
