Tomaintainthesafeandproperconditionoftheinstr mentandtoensure
its safe operation, it is absolutely necessary to carefully and completely
read these operating instructions before using the instrument. These
instructionsmustbefollowedinallrespects.
Observethefollowingsafetyprecautions:
* The instrument must be operated only by persons who
understand the danger of shock hazards and know how to
apply safety precautions. Shock hazards exist anywhere,
where voltages of more than 30 V may occur.
* Do not work alone in shock hazardous environment while carrying
out measurement.
* The maximum allowable voltage between any terminal sockets and
earth is equal to 600 V for voltage and 1000V for Insulation
resistancemeasurement.
* Verify that the test leads are in good condition, e.g. no cracked
insulation,noopencircuitsintheleadsorconnectors.
* Measurementsundermoistambientconditionsarenotpermitted.
* Do not exceed the permissible overload limits of the measuring
ranges.Limitvaluescanbefoundinthetablein“12.Specification”.
SafetyPrecautionsforInsulationResistance
Measurement
* The circuit under test must be switched off, de-energized,
isolated before Insulation or Continuity tests are made.
* The TEST button must not be pressed while connecting the
test leads or while changing ranges.
* The Voltage warning does not function while in STOP WATCH
mode or in MENU structure.
* During an Insulation test, connections must not be touched.
* After insulation tests, capacitive circuits must be allowed
to discharge before disconnecting test leads.
* Test leads and crocodile clips must be in good condition,
clean and with no broken or cracked insulation.

bychangingthe"FunctionSelectorSwitch".
·Connectthetestprobesfirmlytothecircuitundertest.
Note!
Insulation resistance can only be measured at voltage free
object. Hence the circuit under test must be switched off,
de-energized and isolated before carrying out any insulation
resistancemeasurement.
When measuring high-ohmic insulation resistance do not
touchthemeasurementcables.
If an interference voltage > 25V is present within the
system, insulation resistance measurement is disabled.
The instrument defaults to the default voltmeter and
displays the value of the interference voltage on the LCD.
Also the instrument indicates this additionally by an
acousticsignal.
HIGH-VOLTAGE
Do not touch the conductive ends of the test probes
after insulation resistance measurement has been
activatedattheinstrument.
A current with a value of 2 mA (limited by the instrument)
may flow over your body, and although this is not life
endangering,theelectricshockisdistinctlyperceptible.
Ifyouaretaking ameasurement atacapacitive deviceunder test,for
example a cable, it may be charged with as much as
1000V, depending upon the selected nominal voltage. Touching the
device under test after measurement may be life endangering in
suchcases!
5.2 Insulationresistancemeasurement
The instrument provides flexibility for both manual and
continuous (for a pre-selectable time) insulation - resistance
measurement.
5.2.1 ManualInsulationresistancemeasurement:
In manual Insulation resistance measurement, Press and hold "TEST"
keyuntilthedisplayhasstabilized.Insulationresistancemeasurementis
endedwhen the yellowTESTkey is released.Instrumentwillcontinue to
show the last reading for few seconds even after releasing the "TEST
key".
Note!
The instrument's batteries are depleted during insulation
resistance measurement. Only press and hold the TEST key
as long as it is necessary to take the reading in the manual
measurement mode. Continuous measurement as described
belowshouldbeperformed,ifabsolutelynecessary.

mechanism. This is especially advantageous for the observation of
measurementvaluefluctuationsandforcalibrationprocedures.
4.3 BackLit
The instrument is provided with user selectable Back-lit for taking
measurements in poor lighting conditions / dark areas. Refer section 11
on page 14 for switching ON / OFF the backlit from the menu.
By pressing " " and "ON/OFF" key simultaneously
during power ON, the back-lit can be switched ON.

5.2.2 Continuous measurement for a pre-selectable time :
In normal course, the insulation test terminates when the test key
is released and the measured insulation resistance value remains
on display for few seconds after the test key is released.
With the Pre-selectable measurement time feature, the
insulationtestcontinuesforthepre-determinedtime.
Pre-selectabletime:10sec-5min
Refer to the “11. Menu structure” section for how to set the value for
pre-selectable time. Once the time is set it is applicable to all the 5
ranges of Insulation measurement.
nSelect the required value of the time for which the test is
carriedout.
nBrieflyPresstheTESTkey.Theinsulationresistancetestcarries

nThe test terminates automatically after the selected time has
elapsed.
nThe display then flashes the value of measurement at
theenduntilthe Keyispressed.
5.3 Conclusionofmeasurementanddischarging
After the measurement has been completed, any residual voltage is
displayed which may be caused by capacitive circuits. Contact with the
device under test must be maintained. The reduction in voltage can be
directlyobservedattheLCD.
Do not disconnect the device under test until voltage has dropped
below25volts!!
Note:Automaticdischarge!
The capacitive circuits are automatically discharged when
TEST button is released following an insulation resistance test.
This auto discharge facility eliminates the need for the user to
dischargethecircuitundertestmanually.

Refer to the “11. Menu structure” section for how to set the value
forthenoGovalue.
6.2 Storingthemeasuredresistancevalue
lTostorethevalueofresistancepress“STORE”keywhenthe
resistance measurement is in progress. This will store
the resistance measured at the instant the key is pressed.
lThis way maximum 10 readings per range can be stored.
lAfter 10 values are stored for the selected range the
th
11 value when stored will over-write the first value i.e. at any
given point of time only ten readings per range can be
stored.
lThe readings are stored in a volatile memory. Therefore
when the instrument is switched off, the readings are lost.
Recallingthestoredvalues
The stored values can be recalled and viewed in the menu
structure.
Refer to the “11. Menu Structure” section for how to view the
storedvalue.
6.3 Minimum value and Maximum value “MIN/MAX” storage
facility (for all measuring ranges)
With the MIN/MAX function, you can hold the minimum and the
maximum measured value which was applied to the input of the
instrument after activating MIN/MAX. The most important application is
determination of minimum and the maximum value for long term
monitoringofmeasuredquantities.
The function MIN/MAX can be activated in all measuring ranges.
MIN/MAX does not influence analog indication, you can still read the
actualmeasuredvalue.
Apply the measured quantity to instrument prior to activating MIN/MAX
function.

13.3 Fuses
Application of high energy pulse during Insulation resistance
measurement or application of voltage during Continuity and Ohm
measurementwill blow the fuse. If the fuse blows, eliminate the causeof
theoverloadbeforeplacingtheinstrumentbackintooperation!

Specification:
CurrentRating:500mA/500V-6.3mmx32mmwithabreakingcapacity
of10kA.
Recommendedfusemanufacturer:Siba
PartNo.:70-065-63/0.5A
Beabsolutely surethat only thespecified fusesareused !
The use of a fuse with different triggering characteristics,
adifferentnominalcurrentoradifferentbreakingcapacity
exposes the operator, the system and the measuring
instrument to danger. The use of repaired fuses or short-
circuitingofthefuseholderisprohibited.
13.4 Housing
No special maintenance is required for the housing. Excessive
contamination has an adverse effect on isolation and reduces input
resistance.Thesurfacemust be keptcleanfor this reason. Useaslightly
dampened cloth for cleaning. Oil free petrol is recommended for
cleaning.Avoid theusecleansers,abrasivesorsolvents.
