    Theory of Operation Introduction Introduction 2-1. This chapter describes the functional blocks shown in Figure 2-1. Overall descriptions are broken down into Power Supply, Analog Circuitry, and Digital Circuitry. For all measurements, inputs (e.g., Ë and â) are applied through overvoltage (and overcurrent) protection circuits, switched to an appropriate range, and branched into two signal paths.

    NiCd Charging Requirements 2-9. Models 867B use an internal two-state charger. The initial charge state is at approximately 170 mA (±30 mA) to allow for full overnight charging (16 hours minimum). The second charge state is at approximately 40 mA (±15 mA) to allow for battery charge maintenance without full charging from a discharged condition.
