RayTek MI Miniature Infrared Sensor Advanced Valley Hold, Advanced Peak Hold with Averaging

Operation

6.4.5 Advanced Valley Hold

This function works similar to the advanced peak hold function, except it will search the signal for a local minimum.

6.4.6 Advanced Peak Hold with Averaging

The output signal delivered by the advanced peak hold functions tends to jump up and down. This is due to the fact, that only maximum points of the otherwise homogenous trace will be shown. The user may combine the functionality of the peak hold function with the averaging function by choosing an average time, thus, smoothing the output signal for convenient tracing.

The advanced peak hold function with averaging is only adjustable by means of the DataTemp MultiDrop Software.

6.4.7 Advanced Valley Hold with Averaging

This function works similar to the advanced peak hold function with averaging, except it will search the signal for a local minimum.
