                                    The Daetron model MC300 is a compact hand held 4 digit LCD
Digital Capacitance Meter capable of measuring over the full
ranoe of 0.1 pF to 1 FARAD <999.9 mF), in completely
autoranging or manual modes. This instument incorporates so
many features that the user is well advised to read and
understand this manual throughly so as to avoid any
misunderstandings about how the unit works. Complex
procedures involving certain features could lead an unwary
user to think the unit is not working properly.

The MC300 is propably the most powerful hand held Digital
Capacitance Meter on the market today, incorporating new
ideas never before implemented in a unit of such quality and
reasonable cost.

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.

INSTALLING THE BATTERY

To install a battery make sure the power switch is in the
off position. Slide off the back cover and clip the 9 volt
battery to the battery clip and insert it beside the spare
fuse holder. Slide the cover back on. Always use an alkaline
battery as this will last a lot longer than regular zinc
carbon or heavy duty batteries. If using a NI—CAD battery,
the ability to read zener diodes will be impaired as it has
a slightly lower voltage.

IT IS IMPORTANT THAT A GOOD QUALITY BATTERY BE INSTALLED AS
THE WARRANTY IS VOID IF THE UNIT IS DAMAGED BY ft LEAKY BATTERY.

USING THE QPTIONAL AC BATTERY ADAPTOR DAETRON MODEL PS100).

Read the following procedure very carefully. Insert the plug
of the adaptor into the MC300 jack on the top of the unit.
Next insert the adaptor into the AC outlet. Failure to use
this procedure may result in damage to the AC adaptor. Also
using an AC adaptor will allow a higher voltage Zener diodes
to be read. (Max. of 24 VDC). The MC300*s one year warranty
is voided on any units operating on any other than the
DAETRON PS100 or a unit that has been approved by DAETRDN.

GETTING STARTED

Despite it's complicated looking appearance the MC300 is
very easy to use when initially checking capacitors. The
unit is ready to test capacitors when the power switch is
turned on. Before placing the capacitor in the terminal
slots make sure to discharge the capacitor. The terminal
slots have a large wattage resistor connected to them when
the power switch is in the off" position. So if your not
"sure whether your capacitor is discharged make sure to
short the leads or insert the unit into
STEP 4.

Remove the 0.1 µF to 0.2 µF capacitor. Insert the 10 µF' to
20 µF capacitor. Take a reading of this capacitor. If the
value varies from the known value of this capacitor then
adjust P3 until it is the same.

STEP 5.

Remove the 10 µF to 20 µF capacitor. Insert the 1000 µF to
2000 µF capacitor. Take a reaping of this capacitor. If the
value varies from the known value of this capacitor then
adjust PA until it is the same.

MAINTENANCE

INPUT PROTECTION

The MC3G0 incorporates diode clamping and a 1/4 ampere fuse
to protect against charged capacitors. This protection
however is no guarantee that the instrument will not be
damaged if the user forgets to discharge the capacitor
before inserting into the binding posts. So remember to
ALWAYS DISCHARGE YOUR CAPACITORS.

IF YOUR INSTRUMENT STOPS WORKING WORK

FUSE REPLACEMENT

The 1/4 ampere fuse is located under the lid of the battery
compartment. If the fuse is suspected to be open circuited
remove it carefully from its holder. To check the fuse don’t
trust your eyes, check it out with an ohmeter. If it's
defective remove a good fuse from the spare fuse holder and
insert it in the fuse holder. Replace the fuse only with a
1/4 ampere, 250 V, AGC regular blow fuse. Using a fuse with
higher current rating may result in damage to the instrument.
