<Gas Name and Full Scale Display>
Display a gas name, full scale value, etc. that have been set in advance. The following is display example of
GP-6001.
NOTE
NC-6001W offers two reading ranges (low and high ranges).
If the displayed combustible gas concentration rises above the full scale of the low range, the display is
automatically switched to the high range.
On the other hand, if the gas concentration drops below the full scale of the low range, the display is
automatically switched back to the low range.
The low range is indicated by lighting of the WL display, and the high range by lighting of the WH display,
informing the present reading range (low or high range).
Example

Reading range : 0 - 2000 ppm / 0 - 100%LEL

CAUTION
A reading under zero is suppressed with the 10% FS suppression.
A reading that is 10% FS or more under zero is displayed as "-0.0", which prevents an accurate gas
detection and needs the zero adjustment. For information on the suppression function, see "6-4.
