Because on high power the magnification is so high you cannot tell where you are on the surface of the object, and so cannot adjust the position to the place you really want.

When using a compound light microscope and focusing should the lowest power lens should be used?

Yes, when using a compound light microscope, it is recommended to start with the lowest power lens (usually 4x or 10x) to locate and center the specimen before switching to higher magnifications. This helps in getting a broader view and making it easier to focus accurately at higher magnifications.


What power lens should you start with on a microscope?

You should typically start with the lowest power lens (usually 4x or 10x) on a microscope to locate and focus on your specimen. This allows you to have a wider field of view and better control over the focusing before switching to higher power lenses for more magnification.


Which lens should you use to first look at a slide on a microscope?

You should start with the lowest magnification lens, typically the scanning lens (4x or 5x), to locate and center the specimen on the slide. This allows you to get a general overview of the slide before increasing the magnification with higher-power objectives.


How long does it take for a power station to start up?

The start-up time for a power station can vary depending on the type of power plant. In general, it can take anywhere from several hours to a few days for a power station to start up, as it involves bringing the system online, warming up equipment, and ensuring everything is operating safely and efficiently. Advanced technologies and automation systems can help to reduce the start-up time for some power stations.


What is the function of the power switch in the microscope?

The power switch in a microscope is used to turn the microscope on and off by controlling the flow of electricity to the light source and other components. This enables users to easily start and stop the operation of the microscope as needed.

What are automatic headlights on a 2008 dodge avenger?

Automatic headlights are those that will automatically come on when you start the car and should sense the ambient outdoor light and decide whether or not to go to full power mode. (If relative darkness is sensed, full power is used. If relative light is detected, a lower power or 'daytime mode' is used.)

How do you check for power to starter on polaris 400?

Remove the skid plate off the bottom of machine . Take a standard test light , hook the clip to a good ground and touch the probe to the post on the starter . Push the start button and the light should light . If the light works and lights but the starter doesnt work take a small hammer and tap the starter while holding the start button . If the starter workes then the brushes are shot on the starter and need replaced .If the light does not light on tester go to the battery and follow the leads to the starter solonoid . One side of the solonoid should light up without pushing start button , the other side will light up when the button is pushed.


Where is the starter relay on a Ford Excursion and how do I test it?

Not sure of the location.. not particularly familiar with that vehicle. You should always be getting power at the 30 pole with the test light. With the key in the start position, you should see power at the 86 pole. Take a jumper wire and jump power from the 30 pole to the 87 pole. If the starter engages but didn't with the relay installed, there's your problem. If it doesn't, run the test light ground to the 87 pole and the probe to the 30 pole... if you don't get a light at that point, your problem is in the 87 circuit to the starter.
