Voltage Output

The LI‑610 provides a linear analog output, which allows data acquisition systems to record the dew point temperature. The 0 to 50 °C dew point range corresponds to a 0 to 5 V output range (100 mV / °C).

External Control

In addition to front panel controls, dew point temperature can be set by sending a linear 0 to 5 V signal to the Command Input connector on the front of the panel. By using an input signal to control the LI‑610, an automated calibration system can cycle through a range of dew points while calibrating humidity measurement instruments. The LI‑610 measures the input voltage and sets the dew point accordingly (100 mV / °C).
