• Auto calibration or
single calibration
fails.
• The auto calibration values
may not match the cylinder
gas concentrations (auto
calibration only).
• The charcoal filter is
saturated causing an
elevated CO reading.
• The sample gas is not
reaching the sensors
because of a bad
connection.
• The calibration cylinder may
be out of gas or is outdated.
• For PID sensors, the lamp
may need to be cleaned.
• For PID sensors, the
electrode stack may need to
be replaced.
• The sensor for the affected
channel(s) may need
replacement.
1. Check all calibration tubing for leaks
or for any bad connections.
2. Make sure the GX-6000 has been
properly set up for calibration.
3. Change the charcoal filter.
4. Verify that the calibration cylinder
contains an adequate supply of fresh
test sample.
5. Clean the PID sensor’s lamp.
6. Replace the PID sensor’s electrode
stack.
7. If the fail condition continues,
replace the sensor(s).
8. If the difficulties continue, contact
RKI Instruments, Inc. for further
instruction.
• Heart symbol at the
top of the screen
becomes steadily on
or disappears
• A microprocessor error has
occurred.
• Contact RKI Instruments, Inc. for
further instruction.
• Instrument does not
go into low flow
alarm when inlet is
plugged.
• Sensor gasket is not seated
properly.
• Turn the instrument off and remove
the flow chamber. Ensure that the
sensor gasket’s flow fitting
connections are facing up and that
the gasket is secured under the
