Continuity Measurement
A continuity test is used to verify the integrity of connections with a
high-resolution resistance measurement. This is important when you check
Protective Earth connections. Measurements may be adversely affected by
impedances or parallel circuits or transient currents.
Note
If electrical circuits are laid out in a ring, Fluke recommends that you
make an end-to-end check of the ring at the electrical panel.
XW Warning
To prevent possible electrical shock, fire, or personal injury,
measurements should only be done on de-energized circuits.
To measure continuity:
1. Turn the rotary dial to the R
LO
position. See Table 13.
2. 1663/1664 FC: Choose the test lead pair to use with and use the
appropriate terminals for this test.
1662: Use the L and PE (red and green) terminals for this test.
This option is for tests at the ring installation or to verify the connection
between protective earth and neutral at a mains socket. To avoid tripping
the RCD, use the 10 mA test current.
3. Choose the test current polarity with .
The + is positive current. The – is negative current. The ± option makes a
measurement with both polarities. The average between the positive and
negative result shows in the primary display. If you choose the ± option for
polarity, the positive result shows in the secondary display. Press to
toggle between the positive and negative intermediate result.
4. Choose the maximum test current with . To not trip an RCD, use the
10 mA setting for a ring installation test that includes the neutral or phase
wire.
