7. Functional check
Warning:
−
In an explosion-hazardous zone only measuring instruments suited for this zone may
be used.
The neon lamp you fitted (outside the hazardous area) gives an indication of the high voltage.
An electrostatic fieldmeter must be used to measure the efficiency of the anti-static bar.
Measure the charge on the material before and after it has passed the anti-static bar.
The charge measured should have been neutralised after the material has passed the anti-static
bar.
8. Maintenance
Warning:
When carrying out work on the equipment: De-energise the equipment.
Attention:
−
Do not damage the emitter points.
−
Keep the anti-static bar clean.
−
If fouled: clean the anti-static bar with a hard non-metal brush.
−
If heavily fouled: clean anti-static bar with isopropyl alcohol or with Veconova 10 industrial
cleaner (www.eco-nova.nl).
−
Allow the anti-static bar to dry entirely, before energising again.
9. Faults
