Page 6: Power Supply
3. Power supply Mains supply or internal battery powered Battery: rechargeable, 12 V - 7 Ah. Mains: 100 - 240 V~ 3.1. Battery condition The charge condition of the battery can be verified before or during the resistance measurement. In order to achieve that, the operator has to press the battery ... - Page 7 If, during the battery charge, the equipment is turned ON, the charge will be momentarily interrupted, returning to the charge process once the equipment is turned OFF. The rechargeable battery does not show the “memory effect” and there are no restrictions to start charging it as many times as is needed. However the battery could be damaged if remains in deep discharge for a while.

Page 8: Measurement
4. Measurement It should be checked that the item to be measured is voltage free. 1. Before turning the equipment On, connect the test leads to the item to be measured and to the front panel terminals. The alligator clamps in the drawings are only for illustration. 2. - Page 9 6. Turning the test current control clockwise increases the current. Adjust this control until obtaining the desired value or until the current indicator (bargraph) indicates 100%. The bargraph will show the test current value as a percentage of the nominal value selected by using the test current selector .

5. Messages SOURCETRONIC MPK-2000e When turning the equipment On using the On/Off switch, this introductory message appears for a while. During that time, the equipment carries out some functional checking. WAIT... This message appears each time the equipment needs to adjust any parameter in order to optimize the readings. -
Page 11: Some Notes About Accuracy
MPK-2000e has an auto-compensation system that automatically eliminates the error produced by internal offset. Thus, it is not necessary to carry out measurements by reversing the polarity in order to compute the average value. -
Page 12: Rs232 Output
7. RS232 output The equipment has an RS232 data output in the control panel that can be used to register measurements in a serial printer or data collector. The outputs are the following ones: Pin 2: Rx ; Pin 3: Tx ; Pin 5: Gnd; Rate: 4800 bps 8 bits - no parity - 1 stop bit (8,n,1) Note: In order to assure the compatibility with most printers available in... -
