4-18: Part I
Interpretation of the analog output signal depends on the voltage (or
current) AND the currently activated analysis range. To relate the signal
output to the actual concentration, it is necessary to know what range the
instrument is currently on, especially when the analyzer is in the autoranging
mode.
To provide an indication of the range, a second pair of analog output
terminals are used. They generate a steady preset voltage (or current when
using the current outputs) to represent a particular range. The following table
gives the range ID output for each analysis range:
Range Voltage (V) Current (mA)
LO 0.25 8
MED 0.50 12
HI 0.75 16
CAL (0-25%) 1.00 20
