NOTES:

Analog Output 1 is indicated as AO-1 in the Output column.

0 to 10 VDC output is used for the following three examples:
EXAMPLES:
1. When the analog Output Assignment is set for Detector Temperature and the
lower setting is set to 0.00 and the upper setting is set to 100.00, 50
°
C will = 5.0
VDC.
2. When the analog Output Assignments are set for concentrations and the default
upper and lower settings are 0.00 and 0.00, the default settings allow the output
voltage to follow the range limits.
Example: If Range 1 is set to 10 ppm and Range 2 is 100 ppm, in Range 1 10 ppm
will = 10 VDC and in Range 2 100 ppm will = 10 VDC.
3. When the analog Output Assignment is set for concentrations and the lower
setting is set to 0.00 and the upper setting is set to 10.00, the output will no longer
follow the range limit and will be locked to 10 ppm or 10% depending on units
displayed on Measurement screen.
Example: If Range 1 is set to 10 ppm and Range 2 is 100 ppm, in Range 1 10
ppm will = 10 VDC and in Range 2 10 ppm will = 10 VDC.
