Conrad Business
Supplies to introduce twelve
user-friendly handheld test
and measurement devices
from Testo
Ficosa, a top-tier global provider
Conrad Business Supplies has
introduced five families of handheld
test and measurements devices
from leading manufacturer Testo.
The twelve new products of the
770, 760, 755, 750 and 745 families
provide intuitive and user-friendly
means to measure electrical current
and voltage in different settings and
environments. They join over 700
products from Testo already stocked
by Conrad.
The three devices that make up
the Testo 770 range are clamp
meters, ideally suited for current
measurement in switching cabinets.
A unique mechanism which retracts
one of the two pincer arms ensures
that cables, even in constrained
cabinets, can still be easily grabbed.
Similarly innovative are the three
Testo 760 automatic multimeters
that boast function keys in the place
of dials, to provide easier operation.
They also feature automatically
detected measurement parameters
that make it impossible for the user
to enter incorrect settings.
Of the remaining three new families,
there are the two Testo 755 voltage
testers, which are first of their kind
to be capable of measuring both
voltage and current. Next are the
three models of the 750 range that
incorporate novel all-round LED
displays, permitting the results to
be seen from any angle. Finally the
Testo 745 is a non-contact voltage
tester with a range of up to 1,000 V,
with both sound and visual voltage
warnings, plus a filter for high-
frequency interference signals.

at Conrad commented: “With
the available range of test and
measurement products from Testo
now at Conrad, we are determined
to meet our customer’s requirements
for any task, in any location and at
a price that works for them. The
new and carefully selected products
for
measurement
parameters
complements
the
available
environment measurement product
portfolio perfectly.”

minimise current consumption
At the upcoming FashionTech
Ricoh Europe (Netherlands) B.V.
Semiconductor Support Centre
has launched the R5112, a voltage
regulator plus voltage detector
designed to minimise current
consumption. The device offers a
wide operating temperature range
and accommodates a variety of
high demanding applications for
consumer, automotive and industrial
use.
The R5112 features 42V maximum
input voltage and 200mA output
current with an absolute maximum
rating of 50V and is able to tolerate
load-dump peak voltages of 60V
(<200ms) and has a consumption
of only 3.8µA a long stand-by time
of the battery is guaranteed. The
operating temperature range varies
from −40°C to 105°C for consumer
applications and up to 125°C for
automotive and industrial use.
Meanwhile, the output voltage and
threshold voltage has an excellent
accuracy of ±0.6%, as well as a
low temperature drift coefficient of
±60ppm/°C, which make the device
suitable as a high reliable power
source.
As for protection circuits, the R5112
comprises an output short-circuit, an
overcurrent and a thermal shutdown
protection circuit in addition to the
basic voltage regulator circuits. The
fold-back type output short circuit
