WARRANTY
The 'SHANTI' Insulation Tester series is a universal portable
self powered multipurpose instrument with its own brushless AC
voltage generator for checking insulation resistance in the
electrical and electronic fields. This rugged, precision instrument
can locate intermittent shorts, defective electrical connections,
insulation breakdowns or conductor failure due to wear, moisture,
abrasion, deterioration, corrosion or other hostile environmental .
factors.
ITS series insulation tester can be used for locating and trouble
shooting insulation related problems. The insulation tester is also
useful for preventive maintenance. Testing before break down occurs
can greatly reduce further damages and break down time. It will
also reduce periodic overhaul expenses by revealing the electrical
condition of wiring and components which might otherwise be
replaced unnecessarily.
The ITS series insulation tester is the culmination of many years
of 'SHANTI' experience in manufacturing Insulation Testers. The
accuracy is as per clause 9.1of IS 2992. The case is PC molded.
A pair of ‘-’ (Earth) and ‘+’ (Line) terminal socket is provided for
standard probe sets. The generator is driven by a collapsible
permanently tted crank (which folds parallel to the body while
not in use). Self lubricating moulded gears and oil impregnated
bushes are used to eliminate mechanical maintenance of the
generator. It incorporates the 'SHANTI' moving coil movement. The
generator and movement are of heavy duty construction to
provide long periods of trouble free operation.
apparatus or lines to be tested. NEVER MAKE ANY CONNECTION
TO LIVE ELECTRICAL CIRCUITS OR EQUIPMENT. When carrying out
an insulation test between a circuit and the ground, connect the
‘+’ terminal of the tester to the circuit and ‘-’terminal to the
ground.

value directly.
that pointer is pointing to ‘ ’ mark on scale. If not adjust the green
colored zero knob so that pointer points to ‘ ’ mark on the scale.
Now rotate the handle at 160 RPM and boserve the pointer. It should
not deviate from ‘ ’ by more than 0.7mm.
If below mentioned care is taken, the instrument can provide
many years of trouble free service. Like any precision test instrument
the “SHANTI” Tester should not be stored in a place with excessive
dampness, humidity, vibration or heat. Avoid locations where
corrosive gases, oil vapors, moisture, dust, temperature extremes
exist.
A hand driven generator provides the necessary voltage for
the measuring operation. All the components are integrally
enclosed within the same casing. The tester is designed so that
the operator is only required to connect the articles under test
to the terminals and turn the handle of generator. The insulation
resistance value is measured and read out directly on calibrated
meter. To facilitate accurate readout, select the place free from
vibration for the measuring operation.
PRECAUTIONS
Before connecting the test leads of tester, always make certain
that all electrical power is disconnected from the
