Huazheng Electric HZ-5100-I Hand-held High Precision 100A Contact
Resistance Tester I.OverviewThe hand-held Contact Resistance tester
is a high-precision, digital switch detection instrument carefully
developed by the company according to the IEC standard and the
latest electric power executive standard of the People's Republic
of China DL/T845.4-2004.The instrument uses high frequency high
power constant current switching power supply technology, can
measure the micro ohm level contact resistance. Widely used
in all kinds of switches and electrical appliances contact
resistance, circuit resistance and cable wire, welding line contact
resistance measurement, the instrument measurement data is
accurate, stable performance, meet the electric power, power supply
department on-site high voltage switch maintenance and high voltage
switch plant circuit resistance testing requirements. The
output current and measuring resistance are output on the
seven-inch high brightness touch color LCD at the same time. The
measurement results can be output voltage or stored in THE U disk.
The power off storage can satisfy the data query at any
time. II.Performance characteristics1.It has a variety of
protection functions such as back EMF impact, interruption of the
line during the test process, power failure, and overheating of the
power supply, which can reliably protect the impact of the back EMF
on the instrument, and synchronously sound an alarm.2.Intelligent
power management technology, the instrument total work in the
minimum power state, effective energy saving, reduce heat.3.The
instrument can be freely switched between Chinese and English, with
high output voltage and wide measurement range.4.The test current
comes from a high-precision high-current constant-current power
supply, without manual adjustment, and the test is fast and
accurate.5.The four-terminal wiring method is adopted, which
effectively eliminates the influence of the test lead resistance on
the test results.6.Seven-inch high-brightness touch color LCD,
clear display under strong light, full touch screen operation7.The
instrument can be connected to an external printer to print
measurement data, which is convenient for paperless office.
(optional)8.The instrument comes with a perpetual calendar clock
and power-down storage, which can store 1000 sets of test data for
reference at any time. III.Technical indicatorsTest current:
