Instrument event of a fault and during the warranty period, returned to the company or authority, the company will be repaired free of charge, on condition that by the test clearly indicates that the product has indeed corrupted and the user does not disassemble the instrument, manufacturers have the option to repair or replace products. If the instrument is out of warranty or damage was caused by misuse, lack of management, demolition, accident, does not work as a bad environment, and natural disasters, repair costs borne by the user, before starting to repair the company will submit written estimate, Description repair costs. This warranty is limited only to the original purchaser. This warranty does not apply to equipment wear and appearance of the battery. Only for the above guarantee, without any other express or implied warranties, including warranties of merchantability, fitness for rationality and the like for a particular purpose and application of implied warranties. Regardless of any contract, on tort or otherwise, the Company liable for any special, incidental or consequential damages in charge. I. Overview 1.MCH-87E meter manual range is 3 1/2 digit digital multimeter. 2. With a large screen, full-range overload protection and unique design, making it more superior performance of electrical instruments. This series of instruments used to measure: AC and DC voltage, DC current, resistance, diodes, circuit continuity, transistors, capacitors, temperature, LED light-emitting diode and frequency measurements. 3. "misinsertion pen" operation with automatic recognition, sound and light warning, its correspondence with preventing wrong insertion of "mechanical shutter" same. 4. LCD backlit display, and comes with "NCV" (non-contact AC voltage detection) function. Symbol full range of full-scale unit having a display, more convenient to use. The Owner's Manual includes information about safety information and warnings, please read carefully and strictly adhere to all the relevant contents of warnings and precautions. Second, check the box to open the box take out the instrument, carefully check the following accessories are missing or damaged, if any one found missing or damaged, please immediately contact your supplier. * * Instructions a pen an adapter socket * * K-type temperature probe an (equipped with temperature function) III guidelines for the safe operation of the instrument strictly follow GB4793 safety requirements for electronic measuring instruments and IEC61010-1 safety standards for design and production. Full character double insulation overvoltage standard CATII1000V, CATIII600V and pollution grade II safety standards. Failure to indicate the use of the instrument in accordance with the operation might weaken or lose protection devices provided for you. 1. Before use to check the meter and pen, to guard against any damage or abnormal phenomenon, you notice any unusual circumstances: as pen cracked cases, LCD no display, please do not use. Do not use no cover and the rear cover of the instrument does not cover, or a shock hazard. 2. The damaged lead must be replaced, and shall put on the same model or the same electrical specification test leads. 3. When the instrument is measuring, do not touch exposed wires, connectors, input is not used or the circuit being measured. 4. When measuring above 60V DC or AC voltage above 30V, must be careful, Keep fingers pointing the probe barriers to prevent electric shock. 5. In determining the scope can not be measured values, shall rotary switch to maximum range position. 6. Do not apply more than marked on the instrument rated voltage or current between the terminal and the terminal or any terminal and grounding. 7. When measuring function switch must be placed in the correct range of stalls. Before the function range switching, you must disconnect leads the circuit under test is strictly prohibited conversion measurement in gear to prevent damage to the instrument. 8. Before online resistors, diodes or circuit continuity measurement, it must first cut off all power circuits and capacitors exhausted all residual charge. 9. Before measuring current, check the meter's fuse is intact, before the meter is connected to the circuit, it should first turn off the power supply circuit. 1 10. Do not store or use the meter in high temperature, high humidity, flammable, explosive and strong electromagnetic field environment. 11. Please do not change the instrument internal wiring, so as not to damage the instrument and endanger safety. 12. When the LCD display shows the "" symbol, the battery should be replaced to ensure accuracy. 13. The measure should be promptly shut off the power. When a long time, should remove the battery. Between the signal input terminal and COM 1.
