1. SAFETY PRECAUTIONS AND PROCEDURES
This instrument complies with safety Standards EN61557 and EN61010-1 related to
electronic measuring instruments.
CAUTION
For your own safety and to avoid damaging the instrument follow the
procedures described in this instruction manual and read carefully all notes
preceded by this symbol .
When taking measurements:
 avoid doing that in humid or wet places - make sure that humidity is within the limits
indicated in section “environmental conditions”.
 avoid doing that in rooms where explosive gas, combustible gas, steam or excessive
dust is present.
 keep you insulated from the object under test.
 do not touch exposed metal parts such as test lead ends, sockets, fixing objects,
circuits etc.
 avoid doing that if you notice anomalous conditions such as breakages, deformations,
fractures, leakages of battery liquid, blind display etc.
 be particularly careful when measuring voltages exceeding 25V in particular places
(building yards, swimming pools, etc.) and 50V in ordinary places to avoid risks of
electrical shocks.
The following symbols are used:
CAUTION - refer to the instruction manual - an improper use may damage the
instrument or its components

1.1. PRELIMINARY INSTRUCTIONS
 This instrument has been designed for use in environments of pollution degree 2.
 It can be used for tests on electrical installations of overvoltage category III 265V and
550V maximum rated interlinked voltage (and to earth).
 You are recommended to respect the usual safety regulations aimed at protecting you
against dangerous currents and protecting the instrument against improper use.
 Only the original test leads supplied along with the instrument guarantee compliance
with the safety Standards in force. They must be in a good conditions and, if
necessary, replaced with identical ones.
 Do not test nor connect to any circuit exceeding the specified overload protection.
 Do not take measurements under environmental conditions exceeding the limits
indicated in this manual.
 Make sure that batteries are correctly installed.
 Before connecting the test probes to the installation make sure that the right function is
chosen.
EN - 2
TIF900
1.2.
DURING USE
CAUTION
An improper use may damage the instrument and/or its components or injure
the operator.
 Before selecting any function, first disconnect the test leads from the circuit under test.
 When the instrument is connected to circuits never touch any unused terminal.
 Do not measure resistance in presence of external voltages; although the instrument is
protected, an excessive voltage may cause malfunctioning.
CAUTION
If the “low battery” symbol is displayed during use interrupt testing and replace
batteries following the procedure described in paragraph 5.2.
1.3. AFTER USE
 Disconnect the test leads from the circuit under test and switch off the instrument.
 If you expect not to use the instrument for a long period remove batteries.
1.4. OVERVOLTAGE CATEGORIES - DEFINITIONS
Standard EN61010-1 (Safety requirements for electrical equipment for measurement, control
and laboratory use, Part 1: General requirements) defines what a measurement category
(usually called “overvoltage category”) is. At paragraph 6.7.4: Measuring circuits it says:
(OMISSIS)
Circuits are divided into the following measurement categories:

Measurement category IV is for measurements performed at the source of the
low-voltage installation.
Examples are electricity meters and measurements on primary overcurrent
protection devices and ripple control units.

Measurement category III is for measurements performed in the building
installation.
Examples are measurements on distribution boards, circuit breakers, wiring,
including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed
installation, and equipment for industrial use and some other equipment, for
example, stationary motors with permanent connection to fixed installation.

Measurement category II is for measurements performed on circuits directly
connected to the low voltage installation.
Examples are measurements on household appliances, portable tools and similar
equipment.

Measurement category I is for measurements performed on circuits not directly
connected to MAINS.
Examples are measurements on circuits not derived from MAINS, and specially
protected (internal) MAINS-derived circuits. In the latter case, transient stresses are
variable; for that reason, the norm requires that the transient withstand capability of
the equipment is made known to the user.

The measurement is performed according to EN 61557-2 and VDE 0413 part 1.
CAUTION

before performing the insulation test make sure that the circuit under test is
not energized and all relative loads are disconnected
 the insulation measurement requires particolar care and attention to avoid
providing wrong test results and causing damages to third parties
 before the insulation test prepare the plant adequately by disconnecting
everything must not be tested. During the insulation test continuously make
sure that the applied voltage is not accessible to third parties

a measurement with a cable disconnected by mistake may provide a good
result also in presence of a faulty insulation. It’s necessary to take all
possibile cares to avoid that. Once prepared the plant and connected the
measuring cables, make sure that they are correctly connected. In case of
doubt, bifore performing an insulation test, perform a  0.2A measurement
by short-circuiting the cables under test at a point of the plant which is as
far as possibile from the measuring clips. Remove the short circuit before
performing the insulation test

5.1. GENERAL
This is a precision instrument. Strictly follow the instructions for use and storage reported
in this manual to avoid any possible damage or danger during use.
Do not use this tester under unfavorable conditions of high temperature or humidity. Do
not expose to direct sunlight.
Be sure to turn off the tester after use. If the instrument is not to be used for a long period
you are recommended to remove batteries to avoid leakages of battery liquid which may
damage its internal circuits.
5.2. BATTERY REPLACEMENT
When the low battery indication (refer to paragraph 6.1.3) is displayed the batteries are to
be replaced.
CAUTION
Only skilled technicians can open the instrument and replace batteries. Before
removing batteries disconnect the test leads from the input terminals to avoid
electrical shocks.

wires come out is positioned backwards
If the battery pack is re-allocated in a wrong way, the battery compartment can not be
closed. In this case do not force the plastic parts, but re-position the battery pack
correctly before closing
Replace the battery compartment cover making a pressure to close it
Use the appropriate battery disposal methods for your area
5.3. CLEANING
Use a soft dry cloth to clean the instrument. Never use wet cloths, solvents, water, etc.
