3.5.8 Voltages
Conc Voltage (RAW)
Voltage from the PMT proportional to the detected signal from the
reaction cell. This voltage represents the actual measurement of
gas.
High Voltage
The voltage applied to the PMT (normally set to 700 volts ±15 V
for ambient applications).
Analog Supply
+12 V (primary) power supply.
Digital Supply
+5 V microprocessor power supply.
-10V Supply
-10 V reading from the main controller board.
3.5.9 General Settings
Decimal Places
Select the number of decimal places (0-5) used for the
concentration displayed on the front screen.
Concentration Units
Sets the concentration units (ppm, ppb, ppt, mg/m
3
, μg/m
3
,
ng/m
3
).
Conversion Factor
This option only appears if concentration units are set to
gravimetric (mg/m
3
, μg/m
3
, ng/m
3
). You can select either 0°C,
20°C or 25°C. This sets the standard temperature used for
conversion from the 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, 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 how long the instrument backlight will stay on for either
seconds (30), minutes (1, 2, 5, 10, 30), hours (1), or always
on/always off.
Front Screen
This field allows the user to display concentrations on the front
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 front screen. The average is measured over the time period
set in Measurement Settings (refer to Section 3.5.10).
Char 0 has Slash
When enabled, the instrument will display the zero character with
a slash (ø) to differentiate it from a capital ‘O’.
