CHAPTER 3 CONTROLS AND FACILITIES
The method of displaying each channels
information can be selected from one of the
following:
a. Automatic sequencing.
b. Highest reading.
c. Combination of automatic sequencing and
highest reading.
d. Manually selected.
The display can be divided into four parts:
Analogue Display.
Message Display
Digital Display.
Icon Display.
2.2.2 Analogue Display
This consists of 25 segments providing an
indication of the sensor gas reading in the form
of an analogue bargraph which covers the sensor
range between -10% and +110% fsd.
There are two possible modes of operation:
a. Solid in which the segments ll the area
betweenzeroandtheactualgasreading.
b. Single Line in which a single segment
indicates the actual gas reading.
Each of these modes can be operated as either
a rising or falling display.
A peak reading facility is available which maintains
a segment at the highest, or lowest, gas value
obtained by the sensor since the previous peak
reading reset. This is a useful recording tool for
the behaviour of the connected sensor.
