Testing round cartridge type and older style glass automotive fuses will indicate low values of resistance if the fuse is lying on a metal surface when under test. New subway links to the stations are also being made for better access. Due to the fact that each ping represents a round-trip packet, and the situation where packets often use different pathways in either direction, it may indicate a problem in a completely different, possibly closer route. Change the range of the meter to R x 1. Should I join a city tour? The government approved construction of the Tsuen Wan line in , then known as the Tsuen Wan Extension, and works commenced in November Thus, really was 15, before.

One Of The Best Rapid Transit Systems In The World

Guide To Using The MTR In Hong Kong

The Octopus Card There is no "fixed" ticket prices for a single journey, instead, the fare is calculated based on the distance travelled. You can purchase individual single fare tickets at the station through the many vending machines or the service desks, the fare will be calculated based on your final destination.

The interactive machines are easy to use and have instructions in English, simply enter your end station and pay, the machines return change.

Buying single tickets every time you will be riding the MTR is tedious and totally avoidable, I highly recommend you pick up the handy Octopus Card , which will not only save you time and money but you will also be able to use it for all your public transport needs: The Octopus system has spread out to many other sectors beyond transportation.

You can use your Octopus card at McDonalds, 7Elevens, vending machines, etc. Here's more about the Octopus Card, where to get it and how it works. When you use the Octopus Card, you will get a discount on the regular MTR ticket fare, so that's another reason to get it! Once in the station you can purchase your ticket if you don't have one or an Octopus already, then proceed to the turnstiles or barriers.

You must save your ticket which you will need again when you get off the train! Some MTR stations serve multiple lines through several different train platforms. There will be signs posted throughout directing you to the correct platform. You need to keep an eye for a your line and b the direction the train is going by locating the name of the end station of that line.

All train platforms have signs showing which direction the train is running and the waiting time for the next train. Once on the train, the next station is always announced and every station is well-marked with the name both in English and Chinese so you know where to get off: One last thing, the MTR is a popular mode of transport in Hong Kong, once you ride it you will know why.

It transports Hongkoners 3. Rotate the selector knob to the lowest range offered that is greater than the voltage indicated or Reinsert the probes as previously.

The meter may indicate between and as much as volts this time. The range of the meter is important to obtain accurate measurements. If the pointer did not move, it is likely that DC was chosen instead of AC. The AC and DC modes are not compatible. The correct mode must be set. If not set correctly, the user would mistakenly believe there was no voltage present, which could be a dangerous mistake.

Be sure to try both modes if the pointer does not move. Set meter to AC volts mode, and try again. Try not to hold both. Whenever possible, try to connect at least one probe in such a way that it will not be required to hold both while making tests. Some meters have accessories that include alligator clips or other types of clamps that will assist doing this. Minimizing your contact with electrical circuits drastically reduces that chances of sustaining burns or injury. Make sure you've measured the voltage first.

You need to determine whether or not the circuit is AC or DC by measuring the voltage of the circuit as described in previous steps. If the circuit to be tested is AC but the meter will only measure DC amps or vice versa , stop.

The meter must be able to measure the same mode AC or DC amps as the voltage in the circuit, otherwise it will indicate 0. Be aware that most multimeters will only measure extremely small amounts of current, in the uA and mA ranges. These are values of current that flow only in the most delicate electronic circuits, and are literally thousands and even millions of times smaller than values seen in the home and automotive circuits that most homeowners would be interested testing.

This amount of current would likely damage the meter beyond repair. Consider using a "clamp-on" ammeter. Ideal for the homeowner, this meter were to be used to measure current through a ohm resistor across 9 Volts DC. To do this, insert the black probe into the "COM" or "-" jack and insert the red probe into the "A" jack.

Shut off power to the circuit. Open the portion of the circuit that is to be tested one lead or the other of the resistor. Insert the meter in series with the circuit such that it completes the circuit. An ammeter is placed in series with the circuit to measure current. It cannot be placed "across" the circuit the way a voltmeter is used otherwise the meter will probably be damaged.

Current flows from the positive side to the negative side. Set the range of current to the highest value. Apply power and adjust range of meter downward to allow accurate reading of pointer on the dial. Do not exceed the range of the meter, otherwise it may be damaged. Be wary of any filter capacitors or other elements that require an inrush surge current when switched on.

Even if the operating current is low and within the range of the meter fuse, the surge can be many times higher than the operating current, because the empty filter capacitors are almost like a short circuit. Blowing the meter fuse is almost certain if the DUT's device under test inrush current is many times higher than the fuses rating.

In any case, always use the higher range measurement protected by the higher fuse rating and be careful. As mentioned above, you can replace the fuse of the multimeter or just buy a new one.

Not Helpful 5 Helpful Plug them in to a socket to test. Old school incandescent bulbs will read bout ten ohms when cold and "open" when blown.

Screwing in fluorescent should read a slightly higher ohm cold and once again, "open" when blown. When you're done making the battery, you can measure the DC voltage using one of the the DC Volts ranges on the meter. Do not measure resistance ohms with it! Not Helpful 1 Helpful 5. Will this meter allow me to check if I have electrical leakage in the circuitry in my house?

You can check the voltage, current, etc. Not Helpful 4 Helpful 9. Some meters are more accurate than others in the milli-volt scale.

So basically, just move the decimal over. Not Helpful 6 Helpful Depending on what meter you have, but start high and work down to avoid damage. Start with 10 amps, then if the reading is less than 1 amp, move it down to 1 amp and try again, moving down to the next setting as you go. Not Helpful 3 Helpful 7. There are several types of light switch but the most common is the single pole single throw.

It has two wires attached to it. First, make sure the power is turned off. Using the Ohm function of the multimeter, touch one lead to each of the two screws. In the on position the meter should read 0 or close to it. When the switch is off the meter should read I which stands for Infinite, meaning you have an open circuit.

If the switch is part of a circuit that can turn a light on in multiple locations it is a single pole double throw, with three wires or double pole double throw with four wires. They are each tested differently. Not Helpful 8 Helpful 7. When I try to zero it out, the needle pegs to the right and using the adjustment doesn't change the reading. Is something wrong with my meter? Answer this question Flag as How is the multimeter adjusted to measure all the types of voltage current and continuity?

What would happen to the meter if I have the switch set to mA or uA and the red is inserted in the Volts jack? How do you confirm if the current is AC or DC with a multimeter?

Did this summary help you? Tips When you are going to check any part for continuity, you must remove the power. Ohm meters supply their own power from an internal battery. Leaving power on while testing resistance will damage the meter.

If the multimeter stops working, check the fuse. You can replace these at places like Radio Shack etc. Make sure that your multimeter is set to the right setting for the unit that you are measuring otherwise you will not get the correct results or any results. If you don't know something, ask questions and ask someone more experienced. Always check meters on known good voltage sources to verify operational status before using. A broken meter testing for volts will indicate 0 volts, regardless of the amount present.

Never connect the meter across a battery or voltage source if it is set to measure current amps. This is a common way to blow up a meter.

Things You'll Need Multimeter. Consider a digital meter instead of the older analog types. Digital meters usually offer automatic ranging and easy to read displays. Since they are electronic, the built-in software helps them withstand incorrect connection and ranges better than the mechanical meter movement in analog types. Add a photo Upload error.
