Displays & Metering 

Current and voltage monitoring is by digital displays and bargraphs. Voltages 
proportional to output current and voltage are fed to the meter circuits via analogue 
switches IC18, IC20 and IC25 and buffer amplifiers IC19-B and IC24-C. The analogue 
switches switch the voltage derived from the output voltage and current (when the enable 
switch is on), or the output voltage and current settings (when the enable switch is off). 

The voltmeter circuit consists of IC1 and display driver IC2 (front panel circuit diagram). 
The ammeter circuit uses IC5 and driver IC6 (front panel circuit diagram). The input to 
the common bargraph comparator array, IC8 and IC9 (front panel circuit diagram), is 
switched between the current and voltage inputs at 100Hz, as are the voltage and current 
bargraph displays. This is accomplished by the oscillator of IC7-3 (front panel circuit 
diagram) and the analogue switches of IC4.
