  • Page 23: Getting Started

    Supplying Power The SDA601 is DC powered. You may power it with the standard AC adapter, the optional 9.6 V NiCad battery pack, eight standard AA batteries, or a “BP” type external battery pack with the correct voltage and polarity. The external DC power connector is on the left side of the instrument.

  • Page 24: Figure 2- 1: Opening The Battery Compartment

    To install AA batteries or the battery pack, open the battery compartment of the SDA601 by pressing down on the cover and sliding it in the direction of the inscribed arrow, as shown in Figure 2- -1. When the cover tabs line up with the slots in the case, lift the cover away from the instrument.
