where T(°F) and T(°C) are the temperature readings in degrees
Fahrenheit and Celsius, respectively.
V
varies from 1.91 V (at 0° C) to 0.58 V (at 55° C). For best
TEMPOUT
resolution, use the maximum gain for this signal range on the analog
input channel.
The VXI-SC-1102 has a 2 Hz filter on the V
The circuit diagram in Figure 7 provides optional details about the
