used. They must be observed during use.■ The circuit under test must be switched off, de-energisedand isolated before test
connections are made when carryingout insulation and continuity tests.■ Circuit connections and exposed metalwork of an
installationor equipment under test must not be touched.
Rememberremote conductors may be charged to the test voltage.■ The live circuit warning and automatic discharge areadditional
safety features which may fail and therefore safeworking procedures/practices must be observed.■ The voltage function will only
work if the instrument isfunctional and switched on.■ After insulation tests, capacitive circuits must be allowed todischarge before
disconnecting test leads.■ The instrument, test-leads, probes and crocodile clips mustbe in good order, clean and with no broken or
crackedinsulation.■ Ensure that hands remain behind guards of probes/clipswhen testing.■ National Safety Authorities may
recommend the use of fusedtest leads when measuring voltage on high-energy systems.■ Replacement fuses must be of the correct
type and rating.Failure to observe this will result in a safety hazard. ■ The rear cover must be in place whilst conducting
tests.NOTETHE INSTRUMENT MUST ONLY BE USED BY SUITABLYTRAINED AND COMPETENT PERSONS.MMIT200
SeriesInsulation and Continuity TestersUser guideUsers of this equipment and/or their employers are remindedthat National Health
and Safety Legislation requires them tocarry out valid risk assessments of all electrical work so as toidentify potential sources of
electrical danger and risk ofelectrical injury such as inadvertent short circuits. Where theassessments show that the risk is
significant then the use offused test leads may be appropriate.Symbols used on the instrument:GCaution: refer to accompanying
notestEquipment protected throughout by Double Insulation (Class II)cEquipment complies with relevant EU DirectivesEquipment
complies with 'C tick' requirementsDo not dispose of in the normal waste streamMaximum input voltage 600 V rmsApplicationBS EN
61010 defines measurement categories from I to IVrelating transient over voltages and the location within theelectrical installation.
This instrument is designed for use atCategory III (Building installation/distribution board level) up to600 V (maximum) rms to earth
and 600 V (maximum) rmsbetween terminals. It may also be used at Category IV (Primarysupply level) on 300 V rms phase to earth
systems.Display layoutOperationAll circuits must be isolated before an insulation or continuity test.Automatic Voltage detectionThe
instrument will automatically display voltage between 25 Vand 600 Vac or dc when connected to the circuit under test.Remove the
source of any voltage before continuing to test.Test lead check1. Before each use of the instrument, inspect the test leads,prods and
crocodile clips to confirm that their condition isgood, with no damaged or broken insulation.2. Check continuity of the test leads by
firmly shorting theleads together and read the test lead resistancemeasurement directly from the display.Backlight operation1. Turn
the instrument backlight on by selecting the position. Backlight stays on for 1 minute.2. When the backlight is activated, select the
desired testposition.3. Change range or press [TEST] to re-initialise backlight foranother minute.Test lead null To remove test lead
resistance before continuity tests:1. Switch the instrument to [Ω]2. Short test leads together, wait for a stable reading and pressthe
test button on the instrument. The display should read0.00 Ω 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 [Ω]1. Set range switch to [Ω].2.
Connect the red and black test leads to the circuit to betested. The instrument will automatically display continuityresistance when
connected (up to 99.9 Ω).NOTE: If ">100.0 Ω " is displayed the resistance of the circuit isover-range.Continuity Buzzer [ ]1. Set the
instrument to [ ] range.2. Connect the test leads to the circuit to be tested.3. The buzzer will sound automatically when a circuit is
made(<2Ω)4. If a circuit voltage >2 V is detected the test will be inhibited.Insulation testing [MΩ] all instruments1. Set range switch
to [250 V], [500 V] or [1 kV] as available.2. Press and hold down the TEST button to start test. Thedisplay will settle, and show the
insulation test resistance inMΩ.3. If a circuit voltage of >25 V is detected the instrument willgive a warning Beep but allow testing to
continue.If a circuit voltage >50 V is detected, further testing will beprevented.Warning: After testing ensure the display returns to
Zero (circuit isdischarged) before removing test leads.Error messages:>100.0 Ω Continuity over-range<0.01 M Ω Insulation test
result is under-range>1000 M Ω Insulation test result is over-rangeUNC Uncalibrated E17 Instrument not configured to a specific
type.Battery replacementLow battery voltage is indicated by the symbol in thedisplay. To maintain performance the batteries should
bereplaced at this point.Uses 6 x 1.5 V AA (LR6) alkaline dry cells or NiMH rechargeablebatteries.To replace batteries switch off
instrument and disconnect testleads from the circuit under test.Remove the rear battery cover and replace the batteries. Do notmix
old and new batteries.Warning: OBSERVE CORRECT POLARITY. Incorrect batterypolarity could cause batteries to leak and damage
theinstrument.Fuse replacementA blown fuse is indicated by the symbol in the display.To replace the fuse remove battery cover and
replace fuse withtype: 500 mA (F) HBC 50 kA 600 V.Cleaning: Wipe disconnected instrument with a clean clothdampened with soapy
