How do you calibrate an ecg machine?

Most ECG machines calibrate themselves when they are turned on. Older or cheaper models they may need prompting, each is different but the user manual should explain it. Calibration is usually set to 1mV = 10 small squares. This can be manually adjusted if the patient has an unusually large QRS complex. Hope this helps

Is electronic music produced on a semi-acoustic instrument?

NO

Electronic music is produced through the use of a computer

What is the study of electronics called?

Electronics is not a small field the area of electronics is very vast and it can named several ways according to it's area.every field is called engineering.

Electronics and communication is used for communicating and electronics devices

Electronics and instrumentation is used for measurement and measuring tools development.

But all are called engineering.

Why is copper used extensively in electrical systems?

Copper offers good electric and thermal conductivity at reasonable price, and is easily worked into different shapes and sized: Once shaped into thin threads or sheets, copper is not brittle and can easily and repeatedly be bent, allowing for the manufacture of wires, coils from wires and flexible wires.

What is the principle of candle make electricity?

Electricity can be generated directly from a candle in two ways:

  • A candle can generate enough light for an up close photovoltaic cell to generate a small amount of electricity. Several of them in series or parallel around the same candle will generate more electricity (volts or amperes). Many photovoltaic cells are combined together as solar cells to generate electricity from sunlight.
  • A candle can generate enough heat for a thermocouple to generate a small amount of electricity. Several of them in series or parallel around the same candle will generate more electricity (volts or amperes).

The flame could heat up water, which could turn into steam, the steam could turn a generator.

you cannot actually do it unless you use a flame which is a lot bigger and a far more powerful generator.

Difference between electron flow and conventional current?

Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).

What are some emoticons you can make on the computer?

In the 1970s, "Smiley" was fairly bland: a smile or frown. Most were printed large, such as 8 and 1/2" by 11" sheets as a cheap printing to plaster on telephone poles. Of course, all were bright yellow faces with black features. Later, hair was added but never replaced the original Smiley.

What is an electronic signature?

This term can mean different things in different places. Some states recognize that facsimile and email transmissions can be used as "proof" of signature, and have adopted the "electronic signature" definition to refer to these sorts of transmissions and allow them (or restrict them) as evidence of (for example) intent to contract or authentication of official orders.

Other definitions mean an "electronic signature" is the electronic capturing of a physical, handwritten signature, as where you use a scribe at a point-of-sale terminal to "sign" a credit card transaction. Again, the regulations authorize this sort of paperless record as evidence of an intent to be bound by some agreement.

Without such statutes or regulations, the standards would still require a physical piece of paper (or other physical substrate) with a hand-written "signature" before a document would be admissible as proof of an original signature.

In other places, where the concern is for a more robust authentication and non-deniability, the "electronic signature" may be distinguished from a "digital signature", which uses sophisticated encryption techniques for security. There are many interesting uses for digital signatures, including anti-virus protection in critical software.

One effect of using electronic signatures (or digital signatures) is to shift the burden of proof. "You deny you signed, yet I have this electronic record showing you signed, now you have to prove this record is false."

How do you make a led light work?

First, you need know what's relevant parameters you want test such as Lumen, CCT, CRI, distribution intensity curve, IES file, EMC/EMI test and so on

Second, you should find suitable instruments to match your LED light, that can test these parameters

Third, you should know some relevant internation standards, such as CIE, IEC, IESNA, LM-79 Clause and LM-80 Clause.

How does an electric switch help in an electric circuit?

A switch is a means of making (on) or breaking (off) an electrical circuit.

What is the importance of email as an electronic tool in an office?

One advantage to using email is that it is delivered extremely fast. You can send email 24 hours a day and send communication to many people at the same time.

What is the best camcorder for youtube?

Every camera that records is compatible with youtube. If it is a webcam, just upload the file. If it is a camorder, use a video software to upload your video from the camorder to the computer.

How do you program your garrison ea23 electronic safe?

There are several brands and models. Knowing the model is essential. First you have to enter the programming mode for the lock your working with. This is why we need to know. Entering the programming mode and following this with the old 6 digit code. They by entering the new 6 digit code twice, your new code is entered. It really is that easy. Most models use the pound key to enter the star key to exit the programming mode. Searching on line by the products name and model is a way to find the instructions. They are available and are easy to find. Since you have to know the old code to program, the instructions are available.

What electronic device can hold an electrical charge for a period of time and can smooth the uneven flow of electricity through a circut?

That would be a capacitor, which stores charge on it's plates when exposed to a voltage and discharges it when exposed to an input resistance. It can smooth ripples in current by it's tendancy to maintain voltage, so it can simulate the average violtage over time by discharging when the circuit voltage is low.
