Caution:Do not place your finger over the vent(it pressurizes the sensor) to test the flow indicator when gas is flowing to the sensor.removing your finger (the restriction) generates a vacuum on the sensor and maydamage the sensor(voiding the sensor warraty). Positive pressure applications: If the sample pressure is greater than 30 psign an external pressure regulator(optional) is required upsteram of the analyzer to control of sample flow.a pressure regulator with a metallic diaphragm is recommended to prevent high oxygen reading that cuold result from the use of diaphragms constructed of more gas permeable materisls. If other optionoal sample system components such as coiled metal tubing(samples must be colled to at least 35-40℃ for continuous use)，coalescing filters ，scrubbers，etc.are required install the pressure rugulator after the coiled tubing and bofore the other components and the analyzer.a scrubber requires a flow valve upstream for optimum efficiency and response time and that the analyzer flow valve is opened completely. Atmospheric or slightly negative pressure applications: For accurate high ppb and/or low ppm range measurements，an optional simple pump is required downstream of the analyzer to draw the sample through the analyzer.The cacuum drawn on the analyzer and sensor should not exceed 4”of water. Caution:Use ofpump downstream of the sensor requires the floe control valve upstream of the sensor be completely opened to avoid drawing ercessive vacuum in the sensor，which can damage the sensor. If pump over-loading(due to the limitation of low flow rate of the sample gas)is a comsideration，a second throttle valve on the pump’s inlet side may be necessary to provide a bypass path，as illustrated below，to prevent the pump from over-loading and over-heating while miantaining the required sample flow rate within the above-mentioned parameters 展开

These detectors may alter the view of a signals appearance， depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said， the more sampling that is put into the spectrum analyzer the slower it will seem to update， but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken， then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide， with a 32 sampling rate set， this in turn means the 860 will dwell or sit on a portion of the spectrum defined above， take 32 snap shots， and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken， then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice， where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion， then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum， it takes into account how much sampling is selected， then takes it’s digital snapshots on the entire 7.5 MHz， averages those pictures together， then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum， take it’s 32 digital snap shots， average those together， and show the average of the 32 snapshots. 展开
