Teledyne 6200E - Sulfides Analyzer - Manual (Page 75)

Model 6200E Instruction Manual Operating Instructions
M6200E Rev: A1 75
NOTE
On analyzers with the multigas option activated (see section 5.5 and Section 6.8.1) the
titles displayed on the instruments front panel during the previous operation appear as:
LOW range appears as SO2 RANGE
high range appears as H2S RANGE
As the instrument switches from H
2
S mode to SO
2
mode and back, only the reporting
range and analog output associated with the gas currently being measured will be active.
The reporting range and analog output for the gas no being measured will continue to
report the last valid reading.
6.7.6. Auto Range Mode (AUTO)
In AUTO range mode, the analyzer automatically switches the reporting range between two user-
defined ranges (low and high). The unit will switch from low range to high range when the H
2
S
concentration exceeds 98% of the low range span. The unit will return from high range back to low
range once both the H
2
S concentration falls below 75% of the low range span.
When set up to measure a single gas (H
2
S or SO
2
), in AUTO Range mode the instrument reports
the same data in the same range on both the A1 and A2 outputs and automatically switches both
outputs between ranges as described above.
To select auto range mode and set the upper span limits for the high and low ranges, press the
following keystroke sequence.
