例句與造句

1. Analog meter movements are inherently more fragile physically and electrically than digital meters.
2. Inexpensive analog meters may have only a single resistance scale, seriously restricting the range of precise measurements.
3. The secret is to go to a surplus store and to buy one of those old analog meters.
4. For an analog meter movement, DC voltage is measured with a series resistor connected between the meter movement and the circuit under test.
5. Analog meters are also useful where the trend of a measurement is more important than an exact value obtained at a particular moment.
6. It's difficult to find analog meter in a sentence. 用analog meter造句挺難的
7. Meters with electronic amplifiers ( all digital multimeters and some analog meters ) have a fixed input impedance that is high enough not to disturb most circuits.
8. Typically an analog meter will have a panel adjustment to set the zero-ohms calibration of the meter, to compensate for the varying voltage of the meter battery.
9. Resistance measurements on an analog meter, in particular, are of low precision due to the typical resistance measurement circuit which compresses the scale heavily at the higher resistance values.
10. During the first month, the new analog meter was read incorrectly by utility workers and recorded that Sawyer owed $ 7, 000, when he really owed less than $ 5.
11. Galvanometers also had widespread use as the visualising part in other kinds of analog meters, for example in light meters, VU meters, etc ., where they were used to measure and display the output of other sensors.
12. The old analog meters with spinning dials are a bit harder to use ( there you would need to note the position of the dials before and after a fixed period of time and do some math ).
13. For resistance measurements, usually a small constant current is passed through the device under test and the digital multimeter reads the resultant voltage drop; this eliminates the scale compression found in analog meters, but requires a source of precise current.
14. Aircraft deviation from the optimal path is indicated to the flight crew by means of a display dial ( a carryover from when an analog meter movement indicated deviation from the course line via voltages sent from the ILS receiver ).
15. For this reason, digital multimeters often approximate this with a bargraph ( typically with a more rapid reading response than the primary readout ); the most effective of these are arranged in an arc, to simulate the pointer of an analog meter.
16. Modern digital meters ( DVMs ) and some modern analog meters also use electronic input circuitry to achieve high input impedance their voltage ranges are functionally equivalent to VTVMs . The input impedance of some poorly-designed DVMs ( especially some early designs ) would vary over the course of a sample-and-hold internal measurement cycle, causing disturbances to some sensitive circuits under test.
