4.8.4 Change Dilution Ratio
The user can insert an optional dilution fitting on the AreaRAE-
Gamma gas inlet port to dilute the gas sample. The user can
enter a dilution ratio (from 1 to 10) from the programming menu
so that the reading can be compensated to show the actual
concentration of the gas sample with the dilution fitting.
1. “Change Dilution Ratio?” is the third submenu item. Press
[Y/+], the display shows the current dilution ratio: “Dilution
Ratio = xx” with the left most digit flashing.
2. Press the [Y/+] or [N/-] to increase or decrease the value of
the digit. Press [MODE] momentarily to advance to the
next digit. The flashing digit will move to the next digit to
the right. Repeat this process until both digits of the new
dilution ratio are entered.
3. Press and hold [MODE] for 1 second to exit the data entry
mode and move to the next submenu.
4. If there is any change to the existing dilution ratio, the
display shows “Save?” Press [Y/+] to accept the new ratio
and exit the submenu. Press the [N/-] to discard the
changes and move to the next submenu.
