* This refers to the internal voltage level of the function NOT the output
signal level of the Test channel itself.
Once a function is selected, the instrument not only begins to output a signal on the
A3 Analog Output, but a TEST parameter is added to the list of Test Functions
viewable via the Front Panel Display. To activate the TEST channel and select a Test
Function press:
6.4.8.
Using the Dilution Option
The Dilution Ration Option is a software option that allows the user to compensate
for any dilution of the Sample Gas before it arrives at the Sample Inlet on the Rear
Panel of the instrument. Use of this feature requires that the degree of dilution be
known.
Using the Dilution Ration Option is a 4-Step process:
STEP 1: SELECT UNITS OF MEASURE – Follow the procedure defined in
Section 6.4.6.
STEP 2: SELECT THE RANGE – Use the same procedures as described in Sections
6.4.1 through 6.4.5. Make sure that the SPAN Value entered is the
maximum expected concentration of the UN-DILUTED calibration gas
and that the gas is input through the dilution probe.
