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.
