METRAHit.27I Features
All-in-one: milliohm
resistance meter, mega-ohm, multimeter, insulation tester * and data
logger
Compact and rugged for service under harsh conditions and
laboratory use, a single device for many applications
Kelvin connection
(4-wire measurement)
Suppresses influence from conductor and contact resistances on
measuring results
Measuring current can
be selected according to the measuring task:
Adaptation to various resistance measuring requirements and
optimized battery service life
DATA Hold
For quick, reliable measurement and storage of individual
measured values, e.g. voltages at discrete cells in batteries and
emergency power supplies
Overload protection
Protects the instrument in the event of inadvertent connection
to mains power
Insulation resistance
tester *
Testing with 50 to 500 V for components, cables and conductors,
for example in aircraft and in on-board electrical systems
LCD panel with
background illumination *
High contrast, even under adverse ambient light conditions
Compact and
multifunctional
Can be used advantageously in aircraft cockpits as well as in
other constricted spaces, which would otherwise require the use of
several individual instruments.
Mains power or
battery operation *
Furnished with 3 rechargeable NiMH batteries and a charger as
standard equipment for optimized instrument availability and low
operating costs
Calibration
certificate as standard feature
Reduced operating costs for use within ISO 9000 quality systems,
documented traceability
Applications
The METRAHit.27
is a compact, rugged and reliable instrument, which is equally
suitable for precision measuring and recording tasks in the factory,
for on-site service and in the laboratory:
-
Adjustment of shunts
in instrumentation
-
Testing of
electrical connections at conductor bars for openpit mining, in
potential bonding systems, and for industrial and household
applications
-
Testing of cable
resistance, wiring, shunt resistors in PCBs and thick-film
circuits
-
Measurement of
contact resistance in relays, contactors and power interrupters
-
Testing of
resistance in fuses, as well as conductor resistance in heavy
current circuits
-
Testing of winding
resistance in transformers, coils, small motors etc.
-
Testing of discharge
resistance on aircraft, and at aircraft outer skin components
-
Contact resistance
testing in uninterruptible power supplies
-
Measurement of cell
voltages, for example in on-board batteries and emergency power
supplies
-
Contact resistance
testing at welding seams
