This circuit is an improved version of the circuit in Fig. 8-41, with diode input-overvoltage protection and meter-scale adjustments. Meter zero is set by R2, and full-scale deflection is set by R1 (typically, about 4 kΩ). Figure 8-41B shows the values of Rf for nanoammeter and microammeter operation.
