Transport Case for OptiCal and S904 OCAL-TC
Control sensor HT961T00
Labview logging software
1. S904 set point temperature (0-10 V = 0 to 100°C (32 to 212°F)
2. S904 set point RH (0-10 V = 0 to 100% RH)
3. Free to use (0-10 V)
4. Free to use (0-10 V)
5. Free to use (0-10 V)
6. Free to use (0-10 V)
7. Free to use (0-10 V)
8. Free to use (0-10 V)
The acquisition system only measures 0-10 V on every channel so the 4-20 mA
signals from the Optidew are converted to a 0-10 V signal. Channels 1 and 2 are
not available for logging signals. A 500  resistor must be used.
