Square Wave Question

Hall sensor function
A hall effect sensor is a sensor that produces a square wave output that can be directly read and modulated by the ECM (as opposed to an AC wave sensor which produces a sine wave that must be converted). They are used as cam position sensors and ABS wheel speed sensors.
Hall Effect Sensor and How Magnets Make It Works

Inside the transmission , pull the pan ! It's the out put speed sensor.
The A/T OSS sensor is a variable reluctance magnetic pickup located in the rear of the transmission case. The sensor is mounted in the case (24) opposite the rear internal gear (560). The rear internal gear is splined to the output shaft assembly (562). The sensor consists of a permanent magnet surrounded by a coil of wire. As the output shaft and rear internal gear rotate, an alternate current (AC) is induced in the coil by the 'teeth' on the rear internal gear as they pass by the magnetic pickup. Therefore, whenever the vehicle is moving, the A/T OSS sensor produces an AC voltage signal proportional to vehicle speed.
At the TCM, the AC signal is electronically converted to a 5 volt square wave pattern. The square wave pattern can then be interpreted as transmission output speed by the TCM through the frequency of square waves in a given time frame. The square waves can be thought of as a representation of the rear internal gear teeth. Therefore, the more teeth or waves that pass by the magnetic pickup in a given time frame, the faster the vehicle is moving. The square wave pattern is compared to a fixed clock signal internal to the TCM to determine transmission output speed. T

cannot measure ferquency or square wave

Inverters use square wave voltage, which tends to stifle digital circuits. Leaving something stuck, or not working. Sure, the inverter will work for awhile, but then the rigid square wave eventually causes problems.

Inverter is square wave. Square wave interferes with digital circuits sometimes.

take number off back, in little square 4 digit number , and go to casio website, look up tab manual archives. . put in number , download it.

If this problem exists when the load is first applied you are probably having an over-load condition as the sudden inrush of current is more than the ups is rated for. Square wave ups are bad about this.

buy a Cobra lead and torch head already equiped would be you best bet.

Your generator may be putting out a square wave instead of a true sinusoidal (sine) wave.

There is usually a circuit in the microwave which monitors the AC line for timing purposes, and a square wave may not be interpreted correctly.

I would consult the manual or contact the manufacturer or installer.
