  • Page 9: Chapter 2 Setting-Up

    Installing the Batteries Insert four AA batteries as indicated by the diagram located on the inside of the battery compartment. The Model TA465 is designed to operate with either alkaline or NiMH rechargeable batteries. Battery life will be shorter if NiMH batteries are used. If NiMH batteries are used the DIP switch will need to be changed.

  • Page 10: Using The Ac Adapter

    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 meter will be powered by the AC adapter.

  • Page 11: Connecting Ventilation Or Iaq 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 TA465 series meter. 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.

  • Page 12: Using The Pressure Ports (Ta465-P)

    Do not use the instrument or probes near hazardous voltage sources since serious injury could result. Using the Pressure Ports (TA465-P) The TA465-P includes pressure ports that can be used to measure static and differential pressures in ductwork. For more information, Application Note AF-107.
