Power Supply option of HTG3500 Series at 5VDC
Continuous Mode:
When powering HTG3500 series modules at 5VDC in continuous mode, an initial 3-minute stabilization time (ts) is
necessary to reach the temperature and the RH outputs with an optimum accuracy.

Pulsed Mode:
When powering HTG3500 series modules in pulsed mode, accurate temperature and RH measurement is reached
instantaneously. Time up (Tup) must be of 5% of the cycle time. Minimum time up (Tup) is 150 ms. Thus minimum
cycle time is 3s.

Power Supply option of HTG3500 Series at 3.3VDC
At 3.3VDC power supply, there is no measurable impact of type of powering on temperature and RH accuracy.
