Adım Satırları
| [* black] Let's take a quick break from disassembly to investigate the circuit board. | |
| [* black] The yellow box is the power supply circuitry. It provides the three regulated and one unregulated rail used by the device. | |
| [* black] The red box shows the high speed high voltage relays. These switch between ranges. They make a nice soft ping when they activate. | |
| [* black] The orange section is the multiplexer, most function switching occurs here. The large white square is a high voltage precision matched resistor divider from Craddock | |
| - | [* black] The blue and green boxes hold the -4.2V and -6.4V references respectively. The 6.4V zener (shown in image 2) is small, orange and VERY expensive |
| + | [* black] The blue and green boxes hold the -4.2V and -6.4V references respectively. The 6.4V zener (1N4579, shown in image 2) is small, orange and VERY expensive |
| [* black] The purple box shows the multi-slope integrator circuit. The white box is the integrating capacitor | |
| [* black] Lastly, the black cylinder with four wires going to it is a special four-wire resistor used in precision current measurements. |
