W-20-TRMS Digital Voltmeter |
|||
|
The W-20-TRMS digital voltmeter has an indicator with diverse symbols for indicating different functions, as well as two warning symbols: one to show when the fuse is damaged and another one to let you know that the condenser is downloaded. In the digital voltmeter, cracks are indicated according to the selected measurement range. An alarm for errors and an acoustic signal are additional options. This voltmeter will also determine capacitance, frequency and temperature. Software and data cable are included in the delivery. There is another model of voltmeter with multiple functions, graphics, interface and software (multimeter, oscilloscope, logic analyser, etc.) which can be found here. Another similar voltmeter which is easier to use is PCE-DM 22 Voltmeter. At this link you will find an overview of all the different voltmeters available at PCE Instruments. |

| Usage of the W-20-TRMS digital voltmeter | |||
|
With this instrument printed circuit assembly can be checked by testing the different components and verifying conduction. The voltmeter can be also used in the electrical sector due to the fact that it is possible to select a higher voltage range. |
