Do not attempt to charge alkaline batteries.
Using the AC Adapter
The AC adapter can be used to power the instrument or to charge
the NiMH batteries when the DIP switch in the battery
compartment is set to NiMH. If the DIP switch is set to Alkaline,
and the AC power adapter is connected, then the batteries will be
bypassed and the monitor will be powered by the AC adapter. Be
sure to provide the correct voltage and frequency, which is marked
on the back of the AC adapter.
Connecting IAQ or Ventilation Probes
The ventilation and IAQ probes have a “D” shape overmolding on the mini-
DIN connector which must align with the connector at the base of the 7575
monitor. This will ensure the probe is properly connected and remains so
during use. Once connected and turned on, refer to the DISPLAY SETUP for
displaying the desired measurements.
