Only for resistance furnace operation:
Check the pump voltage in the device status window. Normal value is around 7 VDC. The
maximum possible value is 24 VDC. The pump voltage should be in any case much lower than
24V in order to have margin to compensate growing restriction of the flow due to growing
saturation of the chemicals. Values over 10V or even up to 15V are not critical. In case of higher
voltages it is advisable to replace the magnesium perchlorate. And if
this doesn’t help, check for
restrictions due to contamination.
A typical example for this fault could be a combined partial blockage of the glass tube (22) and
of the combustion tube outlet (36).
Make sure that the chemicals are not saturated and that the combustion tube is not blocked.
Usually, these faults caused by contamination occur due to frequent analyzing of samples that
produce a lot of dust, and after a prolonged use of the combustion tube
