TABLE 8-3. Diagnostic Flags and Suggested Actions
Flag
Number
Flag Name
Comments
6
Source
Temperature
Set when the internal temperature is
outside the specified safe operation
limits (
−
35 to 55 °C). If this flag is set
the sensor head will be turned off until
the internal temperature is within the
range
−
30 to 50 °C. If the flag is set and
ambient temperature is within the
specified range, consult with Campbell
Scientific.
7
Source Current
Set when the infrared source current is
outside the prescribed limits. It may
occasionally be set for short periods of
time, but if it persists the user should
consult with Campbell Scientific.
8
Off
Set when the analyzer head is powered
off by the user, the datalogger program,
or the EC100 operating system when the
LIGHT_TEMP
flag is set.
9
Synchronization
Set when sampling errors are detected.
Sampling errors are most often caused
by strong electromagnetic interference.
If the flag persists, consult with
Campbell Scientific.
10
Ambient
Temperature
Set when the ambient temperature is
below
−
30 °C or above 55 °C or when
the air temperature sensor is not
connected. If the user enters a fixed
temperature, this temperature must be
within the range
−
30 to 55 °C.
11
Ambient Pressure
Set when the ambient pressure is outside
the specified limits (55 to 120 kPa) or
the external pressure sensor is
configured but not connected.
12
CO
2
I
Set if CO
2
measurement signal is outside
prescribed limits. It can be turned on
when the measurement path is
obstructed by insects, dust, precipitation,
condensation etc. If it persists, consult
with Campbell Scientific.
13
CO
2
I
o
Set if CO
2
reference signal is outside
prescribed limits. It can be turned on
when the measurement path is
obstructed by insects, dust, precipitation,
condensation etc. If it persists, consult
with Campbell Scientific.
