|Daetron MC300 Level Meter|
|Description||Digital Capacitance Meter|
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.
