e. Click a smart sensor from the menu.
f. Type a label for the smart sensor (optional) and click to
enable or disable the graph (enabled by default).
g. To set up scaling for the smart sensor, click the Enable
Scaling checkbox and fill in the Scaled Units, Multiplier,
Offset, and Scaled Measurement Type fields.
h. Click Save. You can also click Next to move from one
smart sensor to the next.
i. Repeat steps e–h for any additional smart sensors you
need to configure.
Analog Module and Sensor Configuration
You can configure both the global settings for the analog
module that affect all connected analog sensors (logging
interval, statistics, and excitation) and the settings for each
individual analog sensor (enabled logging and graphs,
labels, sensor type, and scaling).
a. Click Module <#>: Analog Sensors Logging from the
menu on the left.
b. Select the logging interval to be used for all analog
sensors, which can be different than the one used for
smart sensors (if applicable).
c. Click the Enable checkbox under Sampling Interval if you
want to log statistics. Enter the sampling interval to be
used for calculating the statistics (must be a factor of
the logging interval). Select the statistics to be logged:
minimum, maximum, average, and standard deviation.
The selected statistics will be calculated between each
logging interval at the sampling interval rate you select.
Each statistical value will then be logged at each logging
interval.
d. Enable “Use excitation power” if you want sensors to
use the 12 V DC excitation voltage provided by the
station. Select warmup and enter the seconds or
milliseconds (5 milliseconds to 120 seconds), or select
continuous. Note that the excitation power selected will
be used for all of the module’s configured sensors.
•With warmup, the station supplies excitation power,
12 V DC, for a brief period prior to each
measurement. This allows you to select the minimum
warm-up time needed to allow for sensor
stabilization while conserving battery power. For
example, if you specify a warm-up of one second and
set the logging interval for the module to one minute,
the station will power the external sensor for one
second, log a measurement, and then turn off the
excitation power for the next 59 seconds. Note that
the excitation mode is automatically set to
Continuous if the warmup time selected is within one
second of or greater than the logging or sampling
intervals.
•With continuous, the station supplies constant
excitation power to the sensor for the entire duration
of the deployment. Continuous mode is required if the
sensor needs more than two minutes of warm-up time.
Important: Continuous mode operation will greatly affect
battery operating life and is not recommended.
Note that excitation power will not be enabled until
logging begins (if “Logging” is blinking on the LCD, then
excitation is not being used).
e. Click Save. You can also click Next to move from one
analog channel to the next.
f. Click one of the four analog sensor channels from the
menu, such as Channel 1 shown in this example.
g. Select “Enable Graph” if you want the sensor data to be
graphed in HOBOlink.
h. Select “Enable this channel” if you want the station to
record data for this channel. If the channel is not
enabled, then it will not be part of the channel count
shown on the LCD.
i. Type a label for the sensor (optional).
j. Select the sensor/input type, which is needed to set the
voltage or current range for the analog input.
k. Click the Enable Scaling checkbox and then enter the raw
and scaled unit values as defined in the sensor manual.
Type the scaled measurement type.
l. Click Save. You can also click Next to move from one
channel to the next.
m. Repeat steps f–l for any additional analog sensors you
need to configure for the module.
