pressing the zero button (F2). If the zero function has been activated then the zero
icon overwrites the single probe icon in the top left of the display. By preventing the
zero button (F2) again this function is cancelled.
Do not exceed the maximum permitted voltage of 30 V AC/DC
with respect to earth potential! Electric Shock danger!
This test will check that the connection between the earth pin in the mains plug of the
appliance and the metal casing of the appliance is satisfactory and of sufficiently low
resistance.
A DC test current of ±200mA is applied between the earth pin of the mains supply plug
and the earth bond test lead clip/probe. The worst-case result is shown on the display.
Press
button (F3) to set the Test Duration and Pass/Fail limit. Use the up,
down, left and right keys to highlight, set, test duration and pass/fail limit. The pass/fail
limit can be calculated whilst in this mode by pressing (Calc) (F3). Enter the cross
sectional area and length of cable and a new limit will be calculated. This can be
overridden by selecting the continuity limit from the list. Press
button (F4) when
complete.

This test can also be used to test the earth bond resistance within an IEC power lead.
Connect the IEC power lead between the EUT power socket and IEC socket on the rear
panel of the Rigel 62353 Plus and commence the test.
The Rigel 62353 Plus display will show real time measurements
during an Earth Continuity test however, the highest reading is
recorded during the test.
This can be used to detect momentary break
in the earth path e.g. damaged power cords or loose mains plug
connections. A Pass or Fail is determined by comparing the peak
value measured during the test with the pre-set continuity limit.
