Thermal Conductivity Analyzer
For nonlinear application, signal that produces from the termal conduc-
tivity, will not correspond to the actual gas concentration. The amplifica-
tion of each range will not agree, therefore, the gain must be preset in order
for the signal to read linearly. To set the gain, the following must be per-
formed in sequence.
NOTE: Before setting up this feature, you must have a span gas
containing 90%-100% of the lowest range of the analyzer.
1. Set unit range to lowest range.
NOTE: For output reversal, the lowest range should be range 3, else
the lowest range is range 1.
2. Connect span gas to span inlet.
3. Use UP/DOWN key to scroll to the CAL-INDEPD function.
4. Hold Escape/Enter control to ENTER position for approximately 10
seconds until the upper right connect display "ok" message.
5. Use UP/DOWN scroll to select SPAN function, then setup the
setting to span level. Press ENTER key to span.
NOTE: You must do step #5 before the analyzer return to analyze
mode. If the analyzer returns to analyze function, you must
repeat step 3-5 again.
6. Set range to nex range'
7. Repeat steps 3-5 until you reach the last range of the row.
