LCD Display

The LCD screen basically represents the data you need. If an ESR meter has a display screen, then while buying, you must check the quality of the display. Sometimes it is not very clear, and the quality it presents is also poor.

The display of the LCD screen must be clear and visible. The large and clear screen shows the data clearly so that you can know the results accurately. Because the readings are not clear, then you might interpret the wrong data.

Auto or Manual Ranging

While buying an ESR meter, you must check either it is auto-ranging or manual ranging. Because the auto-ranging automatically detects and sets the value itself, which is easy and provides comfortable usage. It selects the measurement readings itself and prevents a selection of wrong values.

While the manual ranging sometimes may panic the person because the user has to change the value. So instead of panicking while using, you should buy a meter that has automatic ranging rather than manual ranging.

Automatic Shutting of Screen

The automatic shutting off the screen provides the battery a long and safe life. It prevents the battery from damaging and consuming. Before buying an ESR meter, you must keep in mind the auto-shut of the screen.
