2.2.1 Calibrating the Moisture Samples
To generate calibrated moisture samples, proceed as follows:
Note: Be sure to start with the driest calibration value and proceed to the wetter values, because you cannot readily
go from a wetter valve to a drier value. Wetter to drier changes always require a longer equilibration period.
For example, if you are calibrating a moisture probe over the range of -60°C dew/frost point temperature to
+10°C dew/frost point temperature, start with the -60°C dew/frost point temperature.
1. Check the saturator bottle temperature on the temperature gauge.
2. For each moisture calibration point you wish to generate, look at
Data Tables 2 and 3
(supplied with the MG-101).
Above the line which reads “Generated Dew Points (Deg C),” is a row of values headed “Ambient Temperature
(Deg C).” Find the column corresponding as closely as possible to the temperature measured in Step 1 above, and
read down the column of dew/frost points (dew points) in the table below this temperature heading.
Note:
The moisture value you wish to generate may be in either
Data Table 2
or
Data Table 3
. You will find that
“drier” calibration points are in Data Table 3 while “wetter” values are in Data Table 2.
At this point, the MG-101 operating procedure depends on which table contains your calibration point:
•
If your calibration point is in
Data Table 3
, go to “Using Data Table 3” on page 11 .
•
If your calibration point is in
Data Table 2
, go to “Using Data Table 2” on page 12 .
