7. Troubleshooting
Before troubleshooting any specific issues, Ecotech recommends ensuring the instrument has
successfully completed its warm-up routine and all issues listed in the instrument status menu are
resolved (refer to Section 3.4.4).
Table 9 – Troubleshoot List
Error Message/Problem
Cause
Solution
Flow fault
Multiple possibilities
Refer to Section 7.1.
Pump failed
Replace the internal or external
pump.
Blocked filter or orifice - only
installed in external pump
optioned instrument.
Replace sintered filter and orifice
(refer to Section 6.4.6).
Pressurised measurement
cell
Ensure sample and zero inlets are
maintained at ambient pressure
(vented to atmosphere).
Pressure sensors
Perform a pressure calibration (refer
to Section 5.2).
Or replace sensor if required.
Noisy/unstable readings
Multiple possibilities
Refer to Section 7.2.
Calibration system error
Ensure calibration system is
functioning correctly and is leak free.
Ensure sufficient gas is available for
instrument and an adequate vent is
available for excess gas.
Leaks
A leak in the instrument or
calibration system dilutes the sample
stream and causes low span readings
and noise.
Temperature unstable
A failed temperature control allows
the instrument to drift with ambient
temperature. Verify that both the
cell and mirror temperatures are 50
C  3 C.
Chassis lid not in place causing
instrument to drift with ambient
temperature.
Chassis temperature drifting with
ambient temperature fluctuations.
Stabilise ambient temperature and
remove instrument from direct
ambient heating or cooling.
Hardware fault
Measurement cell internal hardware
loose.
Mirrors have detached or degraded.
