Please note that the PC should be placed in explosion safety zone. For long-distance communication we recommend using an Ethernet connection. Can also choose to revoke the region. PC connectivity, choose to start with instantaneous concentration <habit of recording> and 2 seconds of sampling time (see section 4.3.3). Or, you can hand down menu by observing the instantaneous concentration. Fast Close purge stream 30-60s, and then open. In the purge gas is turned off after a few seconds, the flange will be full of dust gas. Repeat Step 2 several times approach, to ensure that changes to the measurement of gas concentrations have a good copy, which is the volatility of the real process of the opposite. The data from the log files and the flange is not calculated under the conditions of the purge gas rate measurement of gas concentrations. And bring it to the receiver unit and transmitter unit from the window flange end to flange end compared to the ratio of the distance. Users will completely free from staying at the side of the computers by using remote control 100mW green laser pointer ...

From here, you can estimate the flange in the purge gas of the "filling fraction." If two ratios are equal, then the flange is completely filled with purge gas. If the ratio of the gas ratio is less than the length of the flange, the flange is only partially filled with a purge gas. Adjust the amount of purge gas, repeat the test until the flange is full of purge gas. Set the length of the measurement instrument (the optical path through the gas, see section 4.3.5) equal to the receiving unit window to launch from the window unit. Long enough to close the purge stream, fill the gas in the flange, and measure the concentration. Measuring length equal to the reset terminal flange-to-flange distance. Purge flow to increase until its measurement and the measurement as in step 2. Owing to the adoption of photoelectric technology, remote control green laser pointer will be more convenient for users. The torch-like green laser pointer is easier to dissipate heat

For the measurement of gas concentration is zero normal software is: at least once every three months with some of the gas check instrument response. The switch is open at least 70 minutes, filled with enough gas to get high concentrations of at least ten minutes of strong gas response. During the test should not have warning or error occurs. For some instruments, the procedures and unnecessary, because the laser is tracking another absorption line instead of this "zero gas" line (for example, HF instrument H2O line). If you have questions about the instrument, please contact with NEMO. The user doesn’t need to point at the place the speaker is talking about by their hands with the help of remote control 200mW green Laser Pointer.

Check the calibration every 3-12 months (depending on the required accuracy). If necessary, re-calibrated (see below). In each calibration check, save gas record instrument settings and measurement data (setting files and delete files). This is to further the service to track. Optical window on the dust or other contaminants will reduce the signal level. The design makes the instrument does not affect the measurement quality conditions, the instrument allows a considerable reduction in signal quality (down to 10% to 30%). However, if the signal level measurement can not be reduced to the level below the LCD display <low transmission>, then the window should be cleaned. To reduce dust accumulation on the optical window, under normal circumstances, each instrument is configured with a purge unit. If the purge is faulty, the optical window should do some checking. The remote control green laser pointer should be added with warning labels.

Optical window can be worn by non-detergent or solvent cleaning. If there are cracks or damage, the window should be replaced. Since the window is wedge-shaped, the positioning of the new window must be the same with the original window, so that is done to protect the system calibration. Due to external injury, receiver and transmitter calibration may change. Thus, the signal level and less over time. LCD will alternately show ?laser lineup error? and ?Low transmission?. To re-calibrate the receiver and transmitter, follow section 3.3 and 3.5 part of the installation process. Largely out of the application is recommended for the specified number of purge gas is very difficult because it depends on the speed of the gas in the dust, the length of the flange and flange diameter. Flange of the purge flow rate equal to the dust in the gas flow rate of 1 / 10. If you have a few minutes later, the concentration of gas to be measured is completely constant (not zero), you can try the following steps to measure the required purge flow: Remote control 50mW green laser pointer is professional in design.
