The Daetron model MC400 is a compact hand held 4 digit LCD Component Analyser/Capacitance Meter capable of measuring over the full range of 0.1 pF to 1 FARAD (999.9 mF), In completely autoranging or manual modes, this instrument incorporates so many features that the user is well advised to read and understand this manual thoroughly so as to avoid any misunderstandings about how the unit works. Complex procedures Involving certain features could lead an unwary user to thin* the unit is not working properly. The basic method of measuring capacitance involves the use of charging and discharging the capacitor while counting the time of this cycle, the cycle time is converted to display a value which Is equivalent to the value of the capacitor under test, the microprocessor controlling the circuitry senses when the value of any capacitor is over ranged for that value and switches to the next higher range resistor. Component analysing Is carried out by scanning any component mounted In the top 3 receptacles of the transistor socket and monitoring the behavior of the voltage outputs that these components produce. For operating the component analyser at its optimum level see the section on the AC adaptor.
