●

Otherwise, the use of the instrument may cause sparkling, which leads
to an explosion.

Always keep your fingers behind the barrier on test probe during

●

measurement.
Never use the instrument if its surface or your hand is wet.

●

Never open the battery compartment cover while making measurement.

●

WARNING

Do not attempt to take any measurements, if any abnormal conditions

●

are noted, such as broken test probe and cracked enclosure of the
instrument.
Never change ranges with test probe connected to the equipment under

●

test.
Do not install substitute parts or perform any unauthorized modification

●

of the instrument. Return the instrument to Kyoritsu or your distributor
for service and repair to ensure the safety features are maintained.
Do not replace batteries when the surface of the instrument is wet.

●

●

opening the battery compartment cover for battery replacement.

―2―

CAUTION

Always make sure to set the range switch to the appropriate position

●

before making measurements.

Do not expose the instrument to the direct sun, dew fall or extreme

●

temperature and humidity.

When the instrument will not be in use for a long period of time, place it

●

in storage after removing batteries.
Use a damp cloth soaked in water or neutral detergent for cleaning the

●

2.Features

MODEL-3132A is an analogue tester with five ranges for insulation resistance
measurement and continuity testing (resistance tests) of low voltage
installations.

● Designed to safety standards:
IEC 61557-1 (General requirements for measuring equipment for low

voltage distribution systems)

IEC 61557-2 (Equipment for insulation resistance measurement for low

voltage distribution systems)

IEC 61557-4 (Equipment for resistance tests for low voltage distribution

systems)

● Dust and drip proof construction to IP54.

● Three insulation test ranges : 250V/100MΩ,500V/200MΩ,1000V/400MΩ.

● Two continuity test ranges : 3Ω,500Ω

● AC voltage warning measurement can be made on all ranges without

depressing the test button.

● Easy for battery check.

● When the test button is released any charge stored in the circuit under test

is automatically discharged.

● Remaining electric charges can be observed on AC voltage warning range.

● LIVE circuit audible and visual indication.

● Fuse protected.

● Color coded scales and range switch position for easy reading.

● Uses only 6 x 1.5V battery type R6P,1.5V AA or equivalent.
