Power Supply option of HTG3400 Series at 5V
DC
Continuous Mode:
When powering HTG3400 series modules at 5V
DC
in continuous mode, an initial 3-minute stabilization time (t
s
) is
necessary to reach the temperature and the RH outputs with an optimum accuracy.
Pulsed Mode:
When powering HTG3400 series modules in pulsed mode, accurate temperature and RH measurement is reached
instantaneously. Time up (T
up
) must be of 5% of the cycle time. Minimum time up (T
up
) is 150 ms. Thus minimium
cycle time is 3s.
