5.3 Resistance to earth with tripod electrode:
e. g. for antistatic floors
tripod
elekctrode
test object
 Connect the tripod electrode and the upper
socket of the ΩMegaSafe ISO 1Ex with the
measuring line.
 Connect earth (PE) with the lower socket of the
ΩMegaSafe ISO 1Ex.
Accessories: 50m-measuring line on wire reel
art.-no. 73006, Earth clamp art.-no. 73001
Note: In Ex areas long measuring lines has to be
unwounded because of the possible high
inductance.
 Place the tripod electrode on the test object and
weight the electrode with approx. 30 kg
 Test the resistance to earth with the
ΩMegaSafe ISO 1Ex.
5.4 Resistance to earth with electrode for surface
resistance and volume resistivity art.-no. 73012:
e. g. for antstatic table mat
electrode at once
standard weight 2,5 kg

 Connect the electrode for surface resistance and
volume resistivity and the upper
socket of the ΩMegaSafe ISO 1Ex with the
measuring line
 Connect earth (PE) with the lower socket of the
