4.4.4.5. Independent Range Mode (IND)
Selecting independent range mode allows the A1 and A2 outputs to be configured with
different measurement ranges. The analyzer software calls these two ranges LOW and
HIGH. The LOW range setting corresponds with the analog output labeled A1 on the
rear panel of the instrument. The HIGH range setting corresponds with the A2 output.
While the software names these two ranges LOW and HIGH, they do not have to be
configured that way.
Also, in this mode the RANGE Test function displayed on the front panel during
SAMPLE mode will be replaced by two separate functions, RANGE1 & RANGE2.
LOW range = RANGE1 = Range value for output A1 = 0-1500 ppb
H
2
S.
HIGH range = RANGE2 = Range value for output A2 = 0-500 ppb

For T101’s configured to measure both SO
2
and H
2
S in multigas measurement mode:
LOW range = RANGE1 = Range value for output A1= 0-1500 ppm
SO

.
HIGH range = RANGE2 = Range value for output A2 =0-1000 ppm

To select the independent reporting range mode and set the upper measurement limits for
the two outputs, press:

NOTE
In INDEPENDENT range mode the two reporting ranges have separate slopes and offsets
for computing concentration and MUST be independently calibrated.
