1Introduction
The HZO50 current probe has been designed for use with
multimeters and oscilloscopes respectively for accurate,
non-intrusive measurement of AC, DC and complex wave-
form currents.
Using advanced Hall Effect technology the HZO50 can mea-
sure currents accurately with a resolution of 1mA from 5mA
to 30 Amps over the frequency range of DC to 100 kHz.
These features make it a powerful tool for use in inverters,
switch mode power supplies, industrial controllers and other
applications requiring current measurement and/or wave-
form analysis.

Warning
The HZO50 may only be used and handled by qua-
lied personnel. To avoid personal injury, follow
these precautions:
– To avoid electric shock, use caution during installation
and use of this product; high voltages and currents may
be present in circuit under test.

Warning
Thecurrentprobemayonlybeusedandhandledbyqualied
personnel. To avoid personal injury, follow these precautions:
– To avoid electric shock, use caution during installation and use of this
product; high voltages and currents may be present in circuit under
test.
– Do not use the product if damaged. Always connect probe to display
device before it is installed around the conductor.
– Always ensure the probe is removed from any live electric circuit, and
leads are disconnected before removing the battery cover.
– UsetheCurrentProbeonlyasspeciedintheoperatinginstructions;
otherwise the current probe’s safety features may not protect you.
– Adhere to local and national safety codes. Individual protective equip-
ment must be used to prevent the shock and arc blast injury where
hazardous live conductors are exposed.
– Do not hold the Current Probe anywhere beyond the tactile indicator.
– Before each use, inspect the Current Probe. Look for cracks or missing
portions of the Current Probe housing or output cable insulation. Also
look for loose or weakened components. Pay particular attention to
the insulation surrounding the jaws.
– Use caution when working with voltages above 60 VDC,
30 VAC rms or 42 VAC peak. Such voltages pose a shock hazard.
– Useofthisequipmentinamannernotspeciedhereinmayimpair
the protection provided by the equipment.
– CAT III equipment is designed to protect against the transients in the
equipmentinxedequipmentinstallations,suchasdistributionpa-
nels, feeders and short branch circuits, and the lighting systems in
large buildings.
Always inspect the probe and lead for damage before use.
To avoid electric shock, keep the probe clean and free of
surface contamination.
Safety in its use is the responsibility of the operator who
mustbeasuitablyqualiedandauthorisedperson.Ensu-
rethatyourngersarebehindtheprotectivebarrierwhen
usingtheprobe.

Warning
Toavoidinjury,whenusingtheprobeensurethatyourn-
gers are behind the protective barrier. Do not use the probe
if any part of the probe, including the lead and connector(s),
appear to be damaged or if a malfunction of the instrument is
suspected.

4.1 Switch On
Whentheprobeisswitchedon,thegreenLEDwillillumi-
nate.TheLEDstartsashingwhenthebatteryvoltageistoo
lowfornormaloperationandwarnstheuserthatitrequires
changing.ThisprocedureisdescribedinSection4.5.
4.2 Zero Adjustment
The output zero offset voltage of the probe may change
duetothermalshiftsandotherenvironmentalconditions.
To null the output voltage depress the Auto Zero button.
Ensure that the probe is away from the current carrying
conductorwhilsttheprobeisbeingnulled.
4.3 Current Measurement
– SwitchontheprobeandcheckthattheLEDislit.
– Connecttheoutputleadtoanoscilloscope,multimeter
orothermeasuringequipment.
– ZerotheprobeusingtheAutoZerobutton.
– Clamp the jaws of the probe round the conductor en-
suringagoodcontactbetweentheclosingfacesofthe
jaws.
– Observe and take measurements as required. Positive
outputindicatesthatthecurrentowisinthedirection
shownbythearrowontheprobe.
4.4 Auto Power OFF
In order to save battery life, the probe will automatically
switch itself off after approximately 10 minutes. To disa-
bletheAutopowerofffunction,SwitchOfftheprobeand
Switch On whilst pressing the auto zero button. The red
LEDwillilluminateandtheprobewillstayOnuntilswitched
off again.
4.5 Battery Replacement
Warning
To avoid personal injury, always ensure the probe is removed
from any live electric circuit, and leads are disconnected
before removing the battery cover. Never operate the probe
withoutthebatterycovertted.
ThegreenorredLEDwillashwhentheminimumopera-
tingvoltageisapproached.Usethefollowingprocedure.
– Unclamptheprobefromtheconductor,turnitoffusing
the On - Off switch and disconnect the output leads,
fromexternalequipment.

13
Subject to change without notice
– Loosenthecaptivescrewwhichsecuresthebatteryco-
ver.Liftthecoverthrough30°andpullitclearofthepro-
bebody.Replacethebatteryandre-tthebatterycover
andfastenthescrew.
Note:
Replacementwithotherthanthespeciedtypeofbatterywill
invalidate the warranty.
Fit only the type 9 V PP3 Alkaline (MN 1604).
4.6 Maintenance
Cleanthecaseperiodicallybywipingitwithadampcloth
anddetergent.Useisopropylalcoholtocleantheelectro-
nics unit and the probe. Do not use abrasive cleaners or
solvents.Donotimmersetheprobeinliquids.
5 Warranty and Repair
Ourinstrumentsaresubjecttostrictqualitycontrols.Prior
toleavingthemanufacturingsite,eachinstrumentunder-
goesa10-hourburn-in test. This isfollowedbyextensive
functional quality testing to examine all operating modes
andto guarantee compliancewith thespecied technical
data.Thetestingisperformedwithtestingequipmentthat
iscalibrated to nationalstandards. Thestatutory warranty
provisionsshallbegovernedbythelawsofthecountryin
which the product was purchased. In case of any com-
plaints,pleasecontactyoursupplier.
Anyadjustments,replacementsofparts,maintenanceand
repairmaybecarriedoutonlybyauthorizedtechnicalper-
sonnel.Onlyoriginalpartsmaybeusedforreplacingparts
relevant to safety (e.g. power switches, power transfor-
mers,fuses).Asafetytestmustalwaysbeperformedafter
partsrelevanttosafetyhavebeenreplaced(visualinspec-
tion,PEconductortest,insulationresistancemeasurement,
leakage current measurement, functional test). This helps
ensurethecontinuedsafetyoftheproduct.
The productmayonlybeopenedbyauthorizedandqualied
personnel. Prior to working on the product or before the pro-
duct is opened, it must be disconnected from the AC supply
network. Otherwise, personnel will be exposed to the risk of
an electric shock.
