Counter
type readings may also be limited by a
rollover
value. With
rollover
set to 0, the counter
will increase until it reaches 4,294,967,296 (2^32). With
rollover
set to a non-zero value, the
counter will be reset to 0 when it exceeds the
rollover
value. For example, if
rollover
is set to
9999, the counter will be reset to 0 on the 10000 count.
Please note that counter and tipping bucket measurements will keep counting even when
recording is off.
Satlink will allow the setup of multiple measurements on the same digital input. For example, it is
possible to setup both a tipping bucket rate and a tipping bucket accumulation on the same
input.
That being said, some setups that share digital inputs will yield unpredictable results.
o
Setting up any number of tipping bucket and counters on DIn2 with debouncing
will work well.
o
Setting up a tipping bucket and counters without debouncing on DIn2 will not
work correctly as far as debouncing is concerned.
o
Setting up a level measurement will work in combination with any other
measurement.
o
Setting up multiple frequency and period measurements on the same input will
work as long as the measurements do not overlap.
o
For frequency and period readings on the same input, one measurement must
finish before a second one starts for the readings to be correct.
o
For frequency and period readings, SL3 will not hold up one measurement until
another completes.
o
Overlapped frequency and period measurements are not considered a
meaningful setup.
o
Setting up a frequency or period measurement on the same input as a tipping
bucket or counter will not work correctly.
If you want to measure both frequency and count from an input you will need to jumper
it to both digital inputs and setup one measurement for the counter (e.g. counter 1) and
the other for a frequency (e.g. frequency 2).
9.3.8.
Measure Type: Meta
Meta
measurements use the result of another measurement as their basis. Usually, a
Meta
measurement is used to average results of another measurement.
9.3.8.1.
Meta Index
This setting tells Satlink what other measurement this
Meta
measurement refers to.
Why use meta measurements? If you had set up an hourly averaged temperature measurement,
a
Meta
measurement could be set up to be the daily average of all those hourly readings.
Measurement M1
(used for Hourly Temperature)
Measurement Type: Analog
Analog Type: 0-5VA
