Can the Craftsman 73755 amp meter take accurate ac amp readings without separating the hot and neutral wires as the older catalogs stated?

A clamped- or forked-type ammeter can only measure the amps in one conductor at a time. Using it as you suggest would get a reading of 0 amps. This is because the reading of one conductor's amps cancels the other conductor's amps.
Ammeters of this type actually measure the rise and fall of the magnetic field produced by the AC current. Since electrons in one conductor are moving the opposite direction of the other conductor, the magnetic fields cancel each other.
On DC circuits, since there is no rise and fall of the magnetic field, it is constant, these type ammeters always read 0 amps on DC current.

Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
How is a vrs sensor tested with a DVOM?
Back probe both wires of the sensor and use an AC voltage setting or your readings will be bad
Should there be voltage readings across a closed contact?
For all practical purposes NO. The only voltage measured will be the voltage drop of the contact itself. This should be very low if the contact is good.
What are the main difference while applying kirchoffs laws to dc circuits and ac circuits using meter readings?
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.
How might ambient temperature may affect the resistance values you would measure in a circuit?
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
Accurate astrological reading online?
I'm sorry, but "accurate astrological readings" do not exists.
Why constriction is made in clinical thermometer?
The constriction in a clinical thermometer allows for expansion and contraction of the liquid inside without separating the column of liquid. This ensures accurate temperature readings by preventing the liquid from breaking and forming air bubbles.
Why did the need for measurement develop?
For more accurate readings of measurement.
What is the purpose of calibrating an oscilloscope?
to obtain more accurate readings
How can one look for blood preassure readings?
The best place to look for blood pressure readings is at your local doctors office or at a public health office. Both will provide you with accurate readings.
What are normal pressure readings on a 1998 ford explorer air conditioning system?
Varies due to ambient temperature - need a chart for accurate readings
Why do pilots get more accurate readings when they adjust a barometer for the current temperature and and humidity?
the answer is yes
Can psychic readings really be conducted over a phone line?
Many psychics advertise that they do accurate readings over the phone. If you believe in that type of thing there is no reason a phone psychic should be any less accurate than an in-person psychic.
How does measuring equipment still give accurate readings after long term and heavy use?
It needs to be calibrated every year to be sure it is accurate
A thermometer used for measuring food temertures should be easy to read and?
accurate. It should have clear markings for temperature readings and a digital display for easy reading. Additionally, it should have a quick response time to provide accurate readings in a timely manner.
Where to place a hygrometer?
Place the hygrometer in the room or area that you want to monitor the humidity levels. It should be placed away from direct sunlight, drafts, vents, and sources of moisture to ensure accurate readings. Aim to position it at eye level for the most accurate readings.
Is a free horoscope as accurate as a paid one?
It's possible to get really good info from a free horoscope. Check out daily readings in your local newspaper. The should be considered just as valid as paid readings.
