1、G Safety Warnings and Precautions These must be read and understood before the instrument is used. They must be observed during use. IThe circuit under test must be switched off, de-energised and isolated before test connections are made when carrying out insulation and continuity tests. ICircuit co

2、nnections and exposed metalwork of an installation or equipment under test must not be touched. Remember remote conductors may be charged to the test voltage. IThe live circuit warning and automatic discharge are additional safety features which may fail and therefore safe working procedures/practic

3、es must be observed. IThe voltage function will only work if the instrument is functional and switched on. IAfter insulation tests, capacitive circuits must be allowed to discharge before disconnecting test leads. IThe instrument, test-leads, probes and crocodile clips must be in good order, clean a

4、nd with no broken or cracked insulation. IEnsure that hands remain behind guards of probes/clips when testing. INational Safety Authorities may recommend the use of fused test leads when measuring voltage on high-energy systems. IReplacement fuses must be of the correct type and rating. Failure to o

5、bserve this will result in a safety hazard. IThe rear cover must be in place whilst conducting tests. NOTE THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.

6、ded that National Health and Safety Legislation requires them to carry out valid risk assessments of all electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as inadvertent short circuits. Where the assessments show that the risk is significant

7、then the use of fused test leads may be appropriate. Symbols used on the instrument: G Caution: refer to accompanying notes t Equipment protected throughout by Double Insulation (Class II) c Equipment complies with relevant EU Directives Equipment complies with C tick requirements Do not dispose of

8、in the normal waste stream Maximum input voltage 600 V rms Application BS EN 61010 defines measurement categories from I to IV relating transient over voltages and the location within the electrical installation. This instrument is designed for use at Category III (Building installation/distribution

9、 board level) up to 600 V (maximum) rms to earth and 600 V (maximum) rms between terminals. It may also be used at Category IV (Primary supply level) on 300 V rms phase to earth systems. Display layout Operation All circuits must be isolated before an insulation or continuity test. Automatic Voltage

10、 detection The instrument will automatically display voltage between 25 V and 600 Vac or dc when connected to the circuit under test. Remove the source of any voltage before continuing to test. Test lead check 1.Before each use of the instrument, inspect the test leads, prods and crocodile clips to

11、confirm that their condition is good, with no damaged or broken insulation. 2.Check continuity of the test leads by firmly shorting the leads together and read the test lead resistance measurement directly from the display. Backlight operation 1.Turn the instrument backlight on by selecting the posi

12、tion. Backlight stays on for 1 minute. 2.When the backlight is activated, select the desired test position. 3.Change range or press TEST to re-initialise backlight for another minute. Test lead null To remove test lead resistance before continuity tests: 1.Switch the instrument to 2.Short test leads

13、 together, wait for a stable reading and press the test button on the instrument. The display should read 0.00 and display the z symbol. Lead null value is automatically stored until reset. To remove, press the TEST button again with leads open circuit. Continuity Measurement 1.Set range switch to .

14、 2.Connect the red and black test leads to the circuit to be tested. The instrument will automatically display continuity resistance when connected (up to 99.9 ). NOTE: If “100.0 “ is displayed the resistance of the circuit is over-range. Continuity Buzzer 1.Set the instrument to range. 2.Connect th

Battery replacement Low battery voltage is indicated by the symbol in the display.

18、 To maintain performance the batteries should be replaced at this point. Uses 6 x 1.5 V AA (LR6) alkaline dry cells or NiMH rechargeable batteries. To replace batteries switch off instrument and disconnect test leads from the circuit under test. Remove the rear battery cover and replace the batterie
