The
Analog In (Standard)
channel takes readings from a physical analog input, scales the
voltage (or current) to an engineering value, and then performs a simple arithmetic average of
all the values. The settings under the Misc. tab define the information required:
The Analog Input Number specifies the physical input that the analyzer wires are
connected to. The analog input number does not have to be the same as the
channel number.
For Model 8816 or 8832, The High and
Low In Voltage/mA are where the
Voltage or Milliamps are entered.
Typical values are -10 to +10 V for a
voltage card and 4 to 20 mA for a
current card. For the Model 8872, the
High and Low In are assumed to be the
full voltage/current range set on the
input module (e.g., 0-5V or 4-20mA) for
that input.
The High and Low Out Eng Units of the
instrument corresponding to the High or
Low Input are entered.
Channel Specific Settings
For example: If the high input to the data
logger from the instrument is 10V when the
output reading of the instrument is 50°C,
then a High Input of 10V indicates a
corresponding High Output of 50°C.
Or if the low input to the data logger from
the instrument is 0V when the low output
reading of the instrument is 0ºC, then a
Low Input of 0V indicates a corresponding
Low Output of 0ºC
