2.2.3 Using Data Table 2
For calibration points found in Data Table 2 , refer to Figure 6 on page 9 and proceed as follows:
1. Fully close the vent valve by turning it clockwise.
CAUTION! Make the following adjustments slowly, being careful not to overshoot the target value. NEVER
ALLOW THE SYSTEM TO GO TO A VALUE WETTER THAN THE TARGET VALUE. If you overshoot a
value in the wetter direction, you will have to allow the system to equilibrate (dry down) again
before you can proceed.
2. Fully close the
DRY GAS FIRST DILUTION VALVE
by turning it clockwise.
3. Consult
Data Table 2
for the desired dew/frost point temperature and find the corresponding value in the column
headed DRY GAS (SECOND DILUTION) . Adjust the valve on the DRY GAS SECOND DILUTION rotameter to obtain the
value shown in the table.
IMPORTANT:
Be sure to read the steel ball or glass ball (
S
or
G
), as indicated in the table.
4. By referring to the desired dew/frost point temperature in
Data Table 2
, find the corresponding value in either the
column headed WET GAS or the column headed WET GAS DILUTED (a given value appears in one column or the
other, but not both). Adjust the valve on the
WET GAS
rotameter (but not on the Wet Gas Diluted rotameter, which
must remain fully open) to obtain the reading indicated on either the
WET GAS
or the
WET GAS DILUTED
rotameter
scales (whichever is indicated in the table).
IMPORTANT:
Be sure to read the steel ball or glass ball ( S or G ), as indicated in the table.
After equilibrium has been established, the MG-101 will be delivering a calibration gas with the selected dew/frost
point temperature.
After you have completed the calibration or other calibrated moisture operation at this dew/frost point temperature,
either shut down the system (see
“System Shutdown” below), or repeat the steps in this section for the next calibration
point.
2.2.4 System Shutdown
If you are not planning another calibration run, you must shut the system down as follows:
1. Fully open the vent valve by turning it counter-clockwise.
2. Fully close the
WET GAS VALVE
by turning it clockwise.
3. Fully close the DRY GAS FIRST DILUTION VALVE by turning it clockwise.
4. Fully close the
DRY GAS SECOND DILUTION VALVE
by turning it clockwise.
5. Set the
WET/DRY VALVE
to
DRY
.
