Troubleshooting
Instrument does not stabilise during calibration or reading:
Check the instrument is sited in a draught free location.
Ensure the ambient air is clean and free of airborne particles.
Allow the recommended warm up time.
Ensure all solutions are properly prepared.
Check the gas supply is not fluctuating and all hoses and connections are
not leaking. Repair/replace as needed.
Check the nebuliser performance. If unsatisfactory, clean nebuliser as
instructed or replace.
Check that liquid is freely overflowing from the U-tube in the drain cup
and out of the drain tube. If not, check for pinching and leakage and
replace as required.
Check the Aspiration tube is not blocked with particulates. Clean or
replace as needed.
Clean Mixing Chamber.
Clean Burner Tube and Flame Spreader.
Flame goes out during use:
Check the fuel gas supply is providing gas. Correct as needed.
Check the fuel gas hoses and connections for leakage and repair/replace
as needed.
Check the Internal Air Switch on the rear panel is turned to ON.
Check the air supply if connected to an external supply.
Flame does not auto- extinguish on shut down:
Turn off power and gas supplies.
Contact your local agent or BWB for advice.
No chart recorder output:
Check connections on the rear panel and the chart recorder.
Review the Chart Recorder set up. Check the chart recorder
output is set properly.
Using a voltmeter, measure voltages at the terminals on the
back panel. When aspirating deionised water, the voltage will
be very close to zero. When aspirating the ion in question,
there should be a voltage present (up to 2.5V). If these results
are not achieved contact your local agent or BWB for advice.
No computer communication:
Check the USB connection on the rear panel.
Refer to the Software Manual.
A “Serial BallPoint” issue may be encountered whereby the
Microsoft serial port enumerator fails to identify incoming
data correctly. Recent versions of the Microsoft Operating
System no longer support an earlier registry fix. To disable the
“Serial BallPoint” and enable the instrument to connect to the
FP-PC software, navigate to the “Device Manager” and expand
the subfolder labelled “Mice and other pointing devices”. Right
click on “Microsoft Serial BallPoint” and select “Disable”. A
warning message will be displayed, select “Yes”. Re-selecting
the USB port in the FP-PC software should enable connection
to the instrument. Contact your IT support desk or BWB if you
require further assistance.
Printer does not print when readings are taken:
Check the printer operation mode light is illuminated.
Check the printer module is turned ON in the instrument menu.
Check the printer has paper and is aligned correctly.
Check you are working with the instrument in AutoRead mode.
Printer lights do not illuminate:
Check the instrument is turned on.
Check the printer module is turned ON in the instrument.
If you continue to experience printer problems please contact
your local agent or BWB.
