Freq InputType
Specifies the input type to use when measuring the frequency input.
TempC InputType
Specifies the input type to use when measuring the temperature input. The input is
expected to be in Celsius. The processing on the input may be used to convert to
Celsius, if needed. Note: this InputType property, and the associated properties used to
configure the input, are only available when TempCompensation is Yes.
BP InputType
Specifies the input type to use when measuring the barometric pressue input. The input
is expected to be in the same units as S0. The processing on the input may be used to
convert, if needed. Note: this InputType property, and the associated properties used to
configure the input, are only available when BPCompensation is Yes.
InputType
Description: Each Measurement generally requires one or more inputs for the measurement.
Each input is identified by the measurement number and input number (such as M1.I1).
The 8310 has a powerful set of built-in input types that allow measurement of most common
hydrologic and meteorological sensors. You can also define your own custom input function by
writing a basic program whose name starts with “INPUT_”. See Chapter10 for more information
about inputs defined by a basic program.
The different built-in input types are described below:
Voltage
Voltage inputs connect to the analog inputs of the 8310 (Terminal Strip B). The Voltage input
type can make both single ended and differential measurements.
Figure 2 Single Ended Voltage Measurement
The full scale voltage for the measurement is selectable as 0-5 (+/-2.5 for differential) or 78mv.
The following user settings are available:
Switched Power
Specify desired switched power for the input. Note
that this is separate from VREF that is turned on for
all voltage measurements.
Module
I/O module number (the built-in analog module is
module 1)
