3.9.2. Input
The content of this tab is device specific but is similar in set up. This example is for a temperature humidity logger.
This tab allows the user to configure the inputs of
the device. Some devices have fixed inputs which
cannot be changed, others, like this one have the
ability to record internal (fixed) sensors, like the
Temperature and Humidity OR external analog
signals using plug in adapter modules (milliamps
and Volts).
3.9.2.1. Enabled
If checked this input is active if unchecked it
is disabled.
3.9.2.2. Channel Tag
Up to 9 characters may be entered to
describe the channel input. This information
is saved in the device and is displayed on the
Graphs if set up in
Preferences .
3.9.2.3. Channel Type
Select Internal to use the device built in sensor. There is nothing else to set up.
Select External to program the analog input. Select the analog module you will be using
from the drop down menu box
– for example 4 – 20 mA. The default scaling can be
changed. For example the Full Scale value can be set to 100 and the zero scale value
can be set to 0 (as opposed to 4) in this case. You can also set the number of decimal
points
– note that the device can only display 4 characters – assuming it has a display.
You can also enter 5 characters for engineering units. This is used by the local PC
software and is not displayed on the device
– use the ICONS button to enable the
available icons on the display as shown below.
3.9.2.4. Sample Mode
The standard mode is Instantaneous
– in this mode the device takes a single sample at
the sample rate and stores it in the memory. By checking one of the other modes the
device will sample at the maximum sample rate
– 2 seconds, and will save the result –
Average, High Peak or Low Peak at the user set sample rate - thus if the sample rate is
10 minutes, the device will take a sample every two seconds then every ten minutes it
will save the average of the last 10 minutes, or the peak during the last ten minutes
depending on the sample mode selection. NOTE: While this may cut down on memory
use it maximizes the battery load.
If a second channel exists it will have a tab and is set up in a similar way.
