laser pointer should be kept in the place

When the customer uses laser pointer .
Values are P-type probe needle of the 4-20mA current measurement or the embedded temperature sensor used by the instrument itself (for O2 analyzer only in the gas pressure is equal to the ambient air pressure) measured. These <Measurement configuration> (measurement configuration) menu configuration. Max Direct: in the AD converter [0-4096] level of the direct signal maximum. This value and the Dark Direct work together to determine the value of light transmission. Dark Direct: When the laser is turned off a short period of time, measured to the direct signal for the light zero. Max Direct This is the same. Laser temp. (V): voltage across the diode laser is located near the thermistor. It is not allowed to use laser pointer irradiant to the people’s and animals’ eyes.When necessary, the document of  laser pointer  can be referred
The high voltage that the low temperature of the laser. Change the laser temperature will change the laser wavelength. Laser temp. Error: measured laser temperature and the reference value of the voltage between expanding. Should be near 0.000. It shows that the quality of the quality and wavelength stability of the laser temperature regulation. Peltier pump (A): the current caused by the Peltier effect element. Modulation ampl. (V): the high frequency of the laser modulation voltage amplitude. TU / the RU the temp: temperature in the transmitter unit and receiver unit inside the embedded thermal resistance measurement. Extra current input: the current measured in the current input (4-20 mA current input).  laser pointer should be kept in the place.
Air pressure (Bar): in the emission unit inside the embedded pressure sensor measured ambient pressure. Read diagramming the average gas concentration and the instantaneous concentration, transfer and spectra of temperature (if measured). Two different charts can be displayed simultaneously. Click on the axis identifies change the graph scale. The second harmonic signal display equipment for the signal to calculate the gas concentration records. The signal for the examination and analysis of absorption spectra to verify the laser effect validation, fault diagnosis is very useful. Shows a total of three curves: to detect the normal second-harmonic signal (pink curve) and the same signal through two different filters (yellow and blue curves). For some instruments, only a filter to the signal of the device application. The currently active errors and warnings will be to identify a is a cross (x), the error will be identified dash (-). <Save the error log> error directory to save to a text file. <Clear the error log> to clear all errors and warnings from the instrument memory. Instrument can also store the internal state of the log (system log) and the self-test information. The customer should wear the corresponding laser protection goggle of laser pointer .
