NOTE: If you define a gas whose LEL is above 50,000 ppm, the
%LEL reading in Measuring Mode will reflect the
defined ppm ratio, but the ppm reading in Measuring
Mode will not indicate above 50,000 ppm. For example,
if you set the ratio to be 150,000 ppm and set the
catalytic combustible channel to display the reading in
ppm, the gas reading will not indicate higher than
50,000 ppm, the equivalent of 33 %LEL and 5% volume
for this ratio, but will continue to indicate %LEL readings
up to 100 %LEL and %volume readings up to 15
%volume, the equivalent of 150,000 ppm, if the display
units are changed to %LEL or %volume. In addition, all
adjustable ppm parameters cannot be set higher than
50,000 ppm.
• Volt
This value determines the sensor voltage for the catalytic
combustible sensor. It can be set to 1.3 or 2.4. When set to
1.3, the sensor is in methane elimination mode. When set to
2.4, the sensor is reading at full response. Even if not all of
the user-defined catalytic combustible channels are being
defined, the Volt column must have a valid number entered. A
valid number for the Volt column is either 1.3 or 2.4.
