High Voltage
The voltage applied to the PMT (normally set to 650 volts ±15V for
ambient applications).
Conc Voltage (RAW)
Voltage from the sensor proportional to the detected signal from the
reaction cell. This voltage represents the actual measurement of gas.
Conc Voltage
Displays the detector voltage after PGA scaling.
+5V Supply
+5V power supply.
+12V Supply
+12V power supply.
+Analog Supply
+12V (primary) power supply. The value should be within ±2V.
-Analog Supply
-12V (primary) power supply. The value should be within ±2V.

Decimal Places
Select the number of decimal places (0-5) used for the concentration
displayed on the home screen.
Conc. Units
Sets the concentration units (
ppm
,
ppb
,
ppt
,
mg/m3
,
μg/m3
or
ng/m3
).
Conversion Factor
[gravimetric units]
This option only appears if concentration units are set to gravimetric
(
mg/m3
,
μg/m3
or
ng/m3
). Select either
0°C
,
20°C
or
25°C
. This sets the
standard temperature used from conversion for measured volumetric
values.
Temperature Units
Select the units that temperature will be displayed in (
Celsius
,
Fahrenheit
or
Kelvin
).
Pressure Units
Select the units that the pressure will be displayed in (
torr
,
PSI
,
mBar
,
ATM
or
kPa
).
Date
Displays the current date and allows users to edit if required.
Time
Displays the current time and allows users to edit if required.
Backlight
Select the length of time the screen and keypad backlight remain on
after a button press. The setting
Always Off
means the backlight never
turns on; the setting
Always On
means the backlight never turns off.
Home Screen
This field allows the user to display concentrations on the
Home Screen
in two formats. The first is
Inst. only
which displays only the
instantaneous concentration reading, the second is
Inst & Avg
which
displays both instantaneous and average concentration on the
Home
Screen
. The average is measured over the time period set in
Measurement Settings Menu
(refer to Section 3.4.9).
Char 0 has Slash
When enabled, the instrument will display the zero character with a
slash (
0
) to differentiate it from a capital ‘O’.
