Users Manual
Operation
The Product is easy to use. The rotary dial clearly indicates the selected
function. Push buttons help you to quickly modify the test settings. The
large display with backlight shows the test results in clear symbols on a
one-level menu.
Safety Features
Safety and performance are two of the most critical requirements for any
electrical system. Good quality insulation, a properly working grounding
system, and active protection assure the safety of people, electrical
systems and buildings. These factors protect them against electrocution,
fire, and other equipment damage.
Touch Pad
The button is surrounded by a touch pad (see Table 6). The touch pad
measures the potential between the operator and the PE terminal on the
Tester. If the touch pad potential exceeds 100 V, the W symbol above the
touch pad is lit, the PE annunciator in the display is lit, and the beeper
sounds.
Live Circuit Detection
For continuity and insulation resistance measurements, the Product inhibits
the test if the terminal voltage detected is >30 volts ac/dc before the test
starts. The beeper sounds continuously if this voltage is present.
Earth Resistance Measurement
The Product inhibits the test if >10 volts is detected between the test rods.
More information about Earth Resistance measurements is on page 55.
Safety Pretest
The 1664 FC model includes a Safety Pretest feature that detects any
appliances connected to the circuit under test. The Safety Pretest gives
you a warning before you start a test and prevents damage to appliances
from the test voltage. More information about Safety Pretest is on page 26.

Input Terminals
Table 8 shows the input terminals.
XW Warning
To prevent possible electrical shock, fire, or personal injury,
do not use test leads in CAT III or CAT IV environments
without the protective cap installed. The protective cap
decreases the exposed probe metal to <4 mm. This
decreases the possibility of arc flash from short circuits.

Description
Turn on the Tester and press for >3 s. The firmware
version shows when you release .
In IT mode, a loop test or an RCD test is allowed even if
the voltage N-PE is higher than 25 V / 50 V. The default
setting is IT OFF.
Configure the Tester to operate in L-n mode or L-n n-L
mode, see Figure 1.
• In L-n mode, the L and N phase conductors must
NEVER be reversed. This is a requirement in the UK
and other regions. The b icon appears on the
display to indicate that the system L and N conductors
are swapped and the test is inhibited. Investigate and
rectify the cause of this system fault before you
continue. L-n mode also changes the RCD x1/2 trip
time duration to 2000 ms. for UK requirement.
• In L-n n-L mode, the unit allows the L and N phase
conductors to be swapped and tests will continue.
Note
In locations where polarized plugs and outlets are
used, a swapped lead icon (b) may indicate
that the outlet was wired incorrectly. Correct this
problem before you continue with any tests.
The default setting in the UK is L-n. Elsewhere, the default
setting is L-n n-L.

How to Zero the Test Leads
XW Warning
To prevent possible electrical shock, fire, or personal injury,
do not use in CAT III or CAT IV environments without the
protective cap installed. The protective cap decreases the
exposed probe metal to <4 mm. This decreases the
possibility of arc flash from short circuits.
Test leads have a small amount of inherent resistance that can affect a
measurement. Before you do continuity or loop impedance tests, use the
zero adapter to compensate for, or zero, the test leads or the mains cord.
See Figure 2 and Figure 3 for more information about the zero adapter.
