5.2.2. SENSOR MENU
The Sensor menu allows the operator to view various measurement parameters in
real-time. This can be useful for diagnosing various instrument or system problems.
Note that these values are updated in real-time as they are repeatedly scrolled on the
display.

NALOG
S
TEP
This menu exercises the analog output of the system through a five-point step test
that corresponds to the ozone concentration range. With this function, the
instrument will automatically step the analog output (see Section 3.4.1 for details on
the analog output connection) through 5 points from 0 to 100 %, representing the
output configuration of either Voltage or Current (see Table 5-3 for values). The
operator can manually control the stepping by pressing either one of the
UP
/
DOWN arrow buttons.

Point 0-5V Output 4-20 mA Output
0% 0.00 V 4 mA
25% 1.25 V 8 mA
50% 2.50 V 12 mA
75% 3.75 V 16 mA
100% 5.00 V 20 mA
