Operation via power unit
Only use the original power unit for operating the instrument.
Integrity
Before each measurement the complete measuring system
(probe, condensate trap, hoses and plug connections) must be
checked for integrity, e.g. by attaching a compressed rubber
bladder to the tip of the probe. If secondary air is drawn in,
measuring errors may result.
Gas output
During measurement, ensure that the gas output of the
analyser is open, so that the gas can escape unimpeded. If
this is not the case, falsification of the measuring results may
occur.
Condensate trap
Empty the condensate trap when the maximum mark is
reached, at the latest. The pump must be switched off
(otherwise the measuring cells are at risk)!
Measuring cells
The measuring cells contain a small quantity of concentrated
acid or lye, and should be disposed of as special waste.
Measuring instrument
Keeping the measuring instruments in rooms in which solvents
are stored will result in damage to the measuring cells.
Measuring instrument conform with EN 61 326-1 Class B: 1997, EN 61 326-1: 1997
