5. THINGS YOU NEED TO KNOW BEFORE PROGRAMMING
(4) Noise level measurement
Noise level measurement allows you to verify the noise damping effect with respect
to the noise source.
The test measures the noise level of the set surrounding environment.
(a) Executing noise level measurement using the mode switch
1) Set the TEST mode operation.
Set the mode switch to "A" and execute power ON or reset.
2) Start distance level measurement.
The measurement results are indicated by the amplifier side LED.
(b) Executing the communication test using a sequence program
1) Set the TEST mode operation.
Set the test operation mode specification area (RWwm+0H) to "00C0H".
2) Start noise level measurement.
When the TEST mode execution request (RYn5) is turned ON, the noise
level is measured, and the measurement results are stored in the processing
result monitor storage area (RWrm+3H).
The measurement result can be verified using the amplifier side LED as well.
