Understanding SWR Tuning your antenna is mandatory if you want acceptable CB performance. Not tuning your antenna will result in poor transmission and reception performance, and can also result in permanent damage to your radio. You’ll need an SWR meter (available for around $25) in order to tune your antenna.

- Return loss is the difference in power (expressed in dB) between the incident power and the power reflected back by the load due to a mismatch. It can be measured directly in dB with a Spectrum Analyzer or Network Analyzer along with a few key components.SWR is defined as the ratio of the maximum voltage to the minimum voltage in the standing wave. The larger the impedance mismatch, the larger the amplitude of the standing wave. A perfect impedance match would cause no voltage standing wave, so the ratio of the maximum voltage to the minimum would be 1 (1:1).

- Get an electronic pulse meter. Use an electronic pulse meter if you have trouble measuring your pulse by hand, you want to check during exercise without stopping, or if you want a very accurate reading. Purchase or rent one at a local medical supply store or another large retailer.

Industrial Wastewater Flow Measurement Requirements The recorder's chart speed must not be lower than 0.5 inch per hour for strip charts and 7 days per cycle for circular charts. The flow meter's totalizer must be non-resettable and should advance frequently enough to allow accuracy checks in the field (i.e., using a stopwatch).

- SWM stands for single-wire multiswitch and the SWM8 is a single-wire multiswitch that can control up to 8 DIRECTV satellite tuners. That means a single SWM8 can control up to 4 DVRs total (2 tuners per DVR), up to 8 single-tuner receivers total, or a combination (eg. 2 DVRs and 4 single-tuner receivers). The SWM8 should not be confused with the SWM5, which is a SWM that has a smaller capacity than the SWM8.

Standing wave ratio The power standing wave ratio (PSWR) is defined as the square of the VSWR, however this terminology has no physical relation to actual powers involved in transmission. SWR is usually measured using a dedicated instrument called an SWR meter.

Water meters - Can a water meter save you money? So, if you live on your own or in a property with a high rateable value (which cannot be appealed), you may also be paying too much for your water. How does a water meter work and should I get one? A water meter is a device that records the amount of water being used in your home for billing purposes, similar to a gas and electricity meter. Your water company checks your water meter to calculate how much to charge you. A water meter allows your charges to be based on the amount of water you use. Therefore, consider the following factors to determine if you could save with a water meter:

LCD projector The basic design of an LCD projector is frequently used by hobbyists who build their own DIY (do-it-yourself) projection systems. The basic technique is to combine a high color-rendering index (CRI) high-intensity discharge lamp (HID lamp) and ballast with a condenser and collector Fresnel lens, an LCD removed from a common computer display and a triplet lens.

Understanding SWR Adjusting the SWR is just matching the electrical length of your antenna to the desired frequency. This ensures that the impedances of the feedline and the antenna match perfectly, so that all available power is being radiated. To tune your antenna, you will need to use a SWR meter. This device is attached between your antenna and radio. This device measures the amount of signal being reflected into your transmitter to help you measure the quality of your outgoing broad cast as well as any potential threat to your radio.

- When you key your transmitter, MFJ`s InstantRecall checks to see if that frequency has been used before. If so, tuning is instantaneous. If not, MFJ`s IntelliTune algorithm (based on MFJ`s efficient SWR Analyzer technology) measures the impedance, snaps the necessary components in place, and then fine-tunes the SWR.

- The meter wires will be connected in the same manner to measure the. resistance of a circuit component. When functioning as a voltmeter or ohmmeter, the meter has a high internal resistance, and is. connected in parallel to the circuit component, touching both sides to record the measurement.

Ohmmeter Usage Connect the meter’s test probes across the resistor as such, and note its indication on the resistance scale: If the needle points very close to zero, you need to select a lower resistance range on the meter, just as you needed to select an appropriate voltage range when reading the voltage of a battery.
