Indication digit of the indication digit of avometer and precision and precision are avometer the basiccest the mainest also index. Will tell avometer to show digit jumps over high accuracy commonly taller also, conversely contrary. 2.
The measurement technique of avometer and the measurement technique that communicate frequency noisy avometer basically are measured to communicating signal and character, accompany the change that communicates signal frequency, appear all sorts of frequency are answered, affect the measurement of avometer. The avometer measurement to communicating signal, have: of 2 kinds of methods commonly? е of travel of Shan of camel of arrogant island is blocked put in order handsome? .
Function and the avometer that measure limits to differ, its produce manufacturer to will design different function to measure range. Common avometer can check meet volts d.c. , electric current, resistance, connect etc, but some avometer do not install voltaic function to reduce cost. 4.
The avometer ego protection with measure stability and protection good is very good, when inserting the alternate route that express a pen like some avometer, bee of can automatic generation cries call the police... the choose and buy of avometer, not blind covet is cheap, it is practical, good to want with. 5, the use method of avometer 1, avometer should be familiar with before using each function, according to the object that is measured, choose archives correctly, span and watch pen insert aperture. 2, it is when size of pair of the data that be measured are unidentified, should first span switch, park maximum, go place of grain Cheng archives by a large number of Cheng after that switch, make appearance finger indicates the 1/2 above in full scale to be in can. 3, when measuring resistance, after choosing proper fold archives, two watches pen photograph is touched make pressing with a finger points to in null, be like null of deviate of pressing with a finger, should adjust " zero " knob, make index clears, measure an outcome in order to assure accurate. Be like cannot zero or number show a watch to give out low voltage to call the police, answer to be checked in time. 4, when measuring some circuit resistance, must cut off the power source of the circuit that be measured, do not measure electrifiedly. 5, when use avometer undertakes metrical, want to notice the safety of person and appearance equipment, the metallic part that expresses a pen must not be felt with the hand in the test, do not allow electrified switch archives switch, measure in order to ensure accurate, avoid to happen get an electric shock and the accident such as burn down appearance. 6, avometer maintains with maintenance avometer maintains 1.
Do not receive volts d.c. of prep above 1000V or prep above 700V to communicate virtual value voltage. 2.
When wanting to be in Ω and position in functional switch, receive voltage source. 3.
Was not installed good in batteries or rear cover is done not have on when tightening, do not use this list please. Avometer is maintained 1.
If if break,visual examination discovers line, sealing off, make contact silk of short circuit, frit is in charge of, burned-out component, can feel the temperature rise case with a batteries, resistor, transistor, agglomerate collect, can consult circuit graph finds out the reason with unusual temperature rise. 2.
The working voltage that measures voltage law to measure each key to nod is normal, can locate trouble spot more quickly. If measure the working voltage of A/D converter, fiducial voltage,wait. 3.
Examination of short circuit law uses short circuit method commonly in A/D converter method, this kind of method is used morer when repairing instrument of weak report and small report. 4.
Open circuit law disconnects doubtful part from inside overall or unit circuit, if breakdown disappears, state breakdown is in disconnecting circuit. This law basically agrees with the circumstance of circuit existence short circuit. 5.
Measure component law to already narrowed when breakdown when somewhither or a few component, can undertake to its online or measure from the line. When necessary, undertake replacing with nice element, if breakdown disappears, explain component is bad already. CNC Milling CNC Machining
