Monitor Errors
Explanation
File system full. Delete files to
continue
Files will need to be deleted before proceeding with logged
measurements. (See File System menu for more information.)
File system error. Logging failed
Message will appear when there is not enough memory to store
new files. You will want to delete files in order to proceed. (See
File System menu for more details.)
PID sensor error
This indicates one of the following: (1) Clean the sensor, (2) The
lamp needs replacing, (3) replace the electrode pellet, (4) or
replace the sensor
Pump unable to regulate
The pump tries to maintain 1.67 L/min flow rate. When the flow
rate is not maintained, this message will appear.
Reason
: The gravimetric cassette may need to be replaced or
detach any external devices (such as a cyclone). Or it will need
to be serviced.
Set time and date – clock has
been reset
This will appear if the battery was depleted. You will want to
reset the time and date.
NOTE
: The time and date field are used for calibration and
logged files.
Digital-out channel sensor invalid
If digital-out is enabled and a sensor is selected (such as PM)
and you remove that sensor, this monitor warning will appear.
(Re-insert the sensor if desired.)
NOTE
: The Digital-out field will automatically disable and select
the next available detectable sensor.
Sensor not found xxx (i.e., CO)
A warning message will appear when a sensor (gas, toxic, PID,
RH/Temp, or dust) is removed.
NOTE
: The instrument needs to be turned off when sensors are
removed. This is to notify you that a sensor has been removed
or changed.
Sensor found xxx (i.e, CO)
Likewise, a monitor warning message will appear when a
sensor is removed and replaced back in. This is helpful if you
are changing different toxic sensors.
PM disabled
If the user disabled particulates via the particulates setup
screen. Then the pump key will not function.
