Connect the annular electrode and the upper
socket of the ΩMegaSafe ISO 1Ex with the
measuring line
Place the test object on a good insulating
underground.
Weight the annular electrode with about 2,5 kg
e. g. standard weight / electrode 73012
Test the surface resitance with the ΩMegaSafe
ISO 1Ex
5. Measuring arrangements
For some measurements the following optional
equipment is needed:
- One/two tripod electrodes, art.-no. 73013
(EN 1081)
- An annular electrode, art.-no. 73011
(EN 61340-5-1/61340-2-3)
- An electrode for surface resistance and volume
resistivity in accordance with at once standard
weight of 2,5 kg, art.-no. 73012
(EN 61340-4-1/61340-2-3 )
- Measuring lines 4 mm unisulated socket,
art. no. 73009
5.1
Surface resistance with annular electrode and
standard weight of 2,5 kg (art.-no. 73012):
e. g. for antistatic surfaces like antstatic packaging
Connect the tripod electrode and the upper
socket of the ΩMegaSafe ISO 1Ex with the
measuring line
Place the test object on a good insulating
underground.
Connect the second tripod electrode and the
lower socket of the ΩMegaSafe ISO 1Ex with the
measuring line
Place the tripod electrodes at a distance of
100 mm on the test object and weight both with
approx. 30 kg each.
Test the surface resistance with the
ΩMegaSafe ISO 1Ex.
