7. Observe "status indicator" light, when the "status indicator" light flashes,
indicate that the instrument is self-calibrating, when "status indicator" light from
flashing to normally on state, indicating the instrument self-calibration is
completed, can read value at this time.
The instrument can simultaneously display dew point value, volume ratio
and measuring curve during the measurement, the main interface on the top,
the first data is "dew point value", the unit is
℃
; the second data is "volume
ratio", the unit is uL / L , meaning the same as ppmV.
Note:
The first time boot, the time of the sensor self-calibration is slightly
longer, usually 8 ~ 10min, if continuous measurement, do not turn off midway.
After entering the measuring mode, the measuring time of dew point value is 3
~ 5min.
Description:
①
If "status indicator" light is normally on state, and the
dynamic measuring curve on the screen was completely become a straight line,
indicating that the data was stable, can read the data;
②
During the measurement, do not press any keys, to complete the
measurement as soon as possible, save gas, save the measuring time;
③
a sample measurement is completed, continue to measure next
sample, during this process do not have to turn off the power supply, directly
switch to the detected gas;
④
general gas can be directly discharged into the atmosphere, for the
toxic, flammable and explosive gas and precious gas should be properly
handled;
7. Dew point calibration
This machine with calibration function, if the user has standard gas, can
calibrate the sensors on their own
Click on "Calibration" button to enter the "dew point calibration" interface,
the "dew point calibration" screen as shown in Figure 8.
