Preparing the multi EA 4000 for Cl measurements
WARNING
Risk of electric short circuit! In the combustion furnace HTS1500 very high electrical
currents occur in spite of a low voltage (max. 14 V). The combustion tube is part of the
cover of live components.
Only switch on the analyzer with the combustion tube inserted! Always switch off the
analyzer from the mains switch at the rear of the device for conversions and mainte-
nance to the combustion tube or combustion furnace.
CAUTION
There is a risk of burns at the hot the combustion furnace! Allow the basic device to
cool down sufficiently before conversion!
NOTICE
Alkaline salts (hand perspiration) cause crystallizations in the quartz glass when heat-
ing the combustion furnace which reduce the service life of the tube.
Where possible do not touch the combustion tube with your hands. Wear protective
gloves to install the lock on the combustion tube. If necessary, clean the combustion
tube externally with Ethanol before installing it in the combustion furnace.
For Cl measurements a quartz tube is used to which the gas sluice is attached. No dust
trap is attached to the quartz tube.

The quartz tube can be attached to the multi EA 4000 via a coupling element.
