Replacing the spark stand plate

Information

There are a separate tungsten electrode, brush, ceramic insert and spark stand plate for
every matrix.

Replace the spark stand plate whenever you change the matrix.

Switch the instrument off (chapter 9.1, page 39).

Opening the spark
stand

Loosen the 4 holding clamps (1, fig. 9-1) on the spark stand plate (2).

Lift the spark stand plate vertically to the top.

Fig. 9-2

Opening the spark stand plate

Cleaning the spark
stand

Brush the condensate off the surface below the spark stand plate and around the
electrode using the brush from the accessory case.

There is a crush hazard when closing the holding clamps on the spark stand
plate!

•

Close the holding clamps from above.

Place the

spark stand plate of the new matrix

on the spark stand and close the

holding clamps.
