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.

Power-On Options

To select a power-on option, press and the function push button simultaneously and then release . See Table 10 for a description of the options. Power-on options are retained when the Tester is turned off.

			Table 10. Power-On Options
	Push	Power-On	Description
	Button	Option
		Firmware	Turn on the Tester and press for >3 s. The firmware
		Version	version shows when you release .
		IT mode	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
		toggle	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 bicon appears on the
			display to indicate that the system L and N conductors
			are swapped and the test is inhibited. Investigate and
		Line and	rectify the cause of this system fault before you
			continue. L-n mode also changes the RCD x1/2 trip
		Neutral	time duration to 2000 ms. for UK requirement.
		Swap mode	• In L-n n-L mode, the unit allows the L and N phase
		toggle	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.
