Fluke 2042 Safety Measures Prior to usage, inspect instrument for external damage. Prior to any operation, ensure that connecting leads used and electronic load are in perfect condition. If the operator’s safety is no longer ensured, the instrument is to be put out of service and protected against use.
Fluke 2042 Users manual Appropriate Usage The instrument may only be used under those conditions and for those purposes for which it was conceived. For this reason, in particular the safety references , the technical data including environmental conditions and the usage in dry environments must be followed. When modifying or changing the instrument, the operational safety is no longer ensured.

Automatic Mode (Standard setting after switch-on) If the automatic mode is selected the message "SIGNAL" is displayed. (9 d) and (9 j) indicate the signal intensity. Manual Mode Selection is made by means of downward selection ". If the manual mode is selected the messages "MAN " and "SENSE" are displayed.

Fluke 2042 Users manual Cable Locator Mode a) Automatic mode b) Manual mode c) Selective Mode Mains Voltage Detection Carrying out measurement The transmitter should be connected between phase and neutral. First verify that the ground wire is in compliance with the VDE 100 for, when connectiong the transmitter from phase to ground, all parts being connected to ground could be live during failures (in cases where the earth resistance does not comply with the regulations).
Fluke 2042 Users manual Theoretical functional principle 1 The FLUKE Cable Locator consists of a transmitter and a receiver. The signal generated by the transmitter consists of a modulated current. Generating a magnetic field arround a conductor, see figure 1. This electro-magnetic field surrounding the conductor induces a voltage within the receiver coils. For both modes, automatic mode and manual mode, the receiver works with three coils and does, not depend on a position.
Fluke 2042 Users manual Connect terminal (2) of the transmitter to a suitable ground. All other cable leads must also be connected to the transmitter and the same ground. Switch in the transmitter via push button (5). Set the transmitter to "LEVEL I" via button (4). The transmitter function is indicated via the flashing of the signal lamp (3). During the manufacture process, the transmitter has been programmed to display the letter "F". Change the Code via Jumper (7).
Fluke 2042 Users manual To perform the test, it is good to mark the location of the artificial interruption on the opposite side of the wall. Select the sensitivity using button (15) to make sure that the signal "F” is only just receivable. Trace the signal in the wall with the receiver until it is no longer indicated. Localize the artificial interruption by systematically adjusting the sensitivity.
Fluke 2042 Users manual The tracing depth amounts to 0...0,5 meters..The tracing depth depends of medium and application 4 When connecting in live circuits, safety regulations must be followed. The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increased up to factor 5. Locating and tracing of lines, sockets, switches and junctions in house installations circuits (one-pole application) Requirements: • The circuit must be dead.
Fluke 2042 Users manual Locating of line interruptions (one-pole application) Requirements: • The circuit must be dead. • All lines which are not required must be connected to the auxiliary ground in accordance with figure 8. • Connect transmitter to one lead and to an neutral according to figure 8. • Carry out this example as described in the application example. Line interruption in the plastic-sheathed cable.
Fluke 2042 Users manual If the transmitters are connected in accordance with the figure 13, the receiver indicates "C" at the left side of the line interruption. If you continue further than the interruption, towards the right, the receiver displays "F". If you are directly above the interruption, no line code is displayed, due to the overlapping of both transmitter signals.
Fluke 2042 Users manual Error detection for a electrical floor heating (one-pole application) Please also note the connection conditions. If a shield mat or shield wiring is located above the heating wires, no ground connection may exist. If required, separate the shield from the ground connection. The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increased up to a factor of 5. 8 C F F C A second transmitter is required for this application.
Fluke 2042 Users manual Locating Fuses (dual-pole application) When connecting in live circuits, the safety directions must absolutely be respected. 10 Insert into the current circuit of a multifamily residential structure within a socket between L1 and N and switch the transmitter to "LEVEL I". You may assign the signal in the secondary distribution and main distribution by transmitter pre-setting "LEVEL I". Thus, fuses and automatic devices can definitely be assigned to a certain current circuit.
Fluke 2042 Users manual Should the short-circuit resistance amount to more than 20 Ohm, you can try the experiment to detect the error location by means of the line interruption mehtode. You can try with sufficient energy to determine the error location (low ohmic connection) or to burn it in a way ensuring a line interruption.
Fluke 2042 Users manual Detedting the direction of water and heating pipes already installed (one-pole application) Requirements: 13 • The respective water and heating pipes must be suitably grounded. • Connect the transmitter according figure 13. • Carry out this example as described in the application example. The earth of a properly earthed socket is a suitable ground. The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increased up to a factor of 5.
Fluke 2042 Users manual Following lines with higher location depth (dual-pole application) If the dual-pole application is carried out on multi-wire cables (e.g. NYM 3x1.5mm2), the location depth is widely limited. The reason is that the go-and-return lines are installed very closely. Thus, a strong distortion of the magnetic field occurs. The electro-magnetic field may not develop at the bottleneck. This limitation can easily be eliminated when using a separate conductor to simulate the return line.
Fluke 2042 Users manual 16 • Set the receiver to automatic mode. • Now, search or trace the conductor by means of the signal intensity (9e + 9j) displayed. When circling the receiver slowly across the conductor to be searched, the display values change considerably. The display of the maximum signal intensity is performed directly via the conductor. 2m The signal intensity level decreases with increasing distance of the fed-in signal (transmitter).
Fluke 2042 Users manual Sorting or determination of conductors already installed (double-pole application) Requirements: 19 • Any exisiting circuits within the cable must be voltagefree. • The lead terminals must be twisted and electrically connected between each other • You need several transmitters, with different transmitter signals (A to F or 0 to 9). • Connect the transmitter according to figure 19. • Carry out this example as described in the application example.
Fluke 2042 Users manual Setting the Codes 6a Make sure that the instrument is switched off before setting the codes. • Remove the batteries from the transmitter in compliance with section 8.2. • Remove the jumper within the battery case (6 a). • Place the batteries respecting correct polarity. • Switch on the transmitter pressing button 5. • Select the required code using button 4 Code selection can be made as follows (A, F, E, H, O, O, C).
Fluke 2042 Users manual Reverse polarity of batteries may destroy the instrument. Furthermore, they may explode or ignite Only use batteries as described in the technical data section! (6 x 1,5 V type IEC LR6, Mignon). Never try to disassemble battery cells ! The battery contains very strong base chemicals. Danger of causticization ! If the battery contents come in contact with skin or clothing, rinse immediately with water.
Fluke 2042 Users manual If an instrument is not used over an extended time period, the batteries must be removed. Should the instrument be contaminated by leaking battery cells, the instrument has to be returned for cleaning and inspection to the factory. If an instrument is not used over an extended time period, the accumulators or batteries must be removed. Should the instrument be contaminated by leaking battery cells, the instrument has to be returned for cleaning and inspection to the factory.
