Figure 20. Response Factor and Memory Slots
Response factors built into the 2020ComboPRO are used to correct for the response
of the PID to a specific compound. These correction factors are often called
response factors (RF).
The 2020ComboPRO has 15 memory slots. Each memory slot can store one preset
RF. Library/RF selections simplify Memory Slot programming and provide
standard response factors for approximately 100 compounds. CHOOSE FROM
PRESETS allows you to select an entry from a pre-programmed Library. The name,
response factor and three alarm levels are all set from the library.
To select a preset to program the selected Memory Slot:
Press MENU, and then use the DOWN ARROW soft key to highlight
“Memory Slots”, then press the SELECT soft key.
To select a memory slot:
Press the DOWN ARROW key until the memory slot you wish to use is
highlighted. Press the SELECT key.
The memory slot compound, RF, TWA, STEL, and Peak alarm value are
displayed. Press the DONE key to return to the main menu.
To edit a memory slot:
1. Press MENU, then the DOWN ARROW key to highlight “Memory Slot”,
then press SELECT.
2. Press the SELECT key to view the “Memory Slot” content and then press
