Brief introduction HT-702 comes with a large LCD display and
flexible rotating mouse controller. If coupled with computer to run
the powerful operating functions. Small size, high accuracy. With
superior performance, advanced features, but also has a small
tester compact and flexible, easy operation and high reliability.
Products features1.The tester with standard 4-phase voltage
and 3 phase current output that can carry out combination of
various types of output protection testing easily. Each phase
voltage can output to 120V and 3 phases in parallel can up to 120A.
The fourth phase voltage Ux is multifunctional voltage that can be
set to four kinds of 3U0 or synchronous voltage or other certain
voltage output.2.Stand-alone operation, by rotating the mouse to
operate through the large-screen LCD. Can test a variety of relays
and microcomputer protectors and simulate complex transient,
permanent, conversion of failures to test. Boot to use, easy to
operate3.Dual operating mode, connect computer to run, through
Windows operating software can complete large and complex
calibration task with highly automatization, can easy to test and
scan various of protection values, real-time storage test data,
display vector graph, draw fault waveform, online print reports,
etc.4.Powerful software: can complete large and complex calibration
task with highly automatization.5.Many of switch contacts: relay
tester is 8 contacts inputted and four pairs of idle contacts
outputted. The input contact is idle contacts compatible with 0 ~
250V potential contacts, that can be intelligent automatic
identified. The contacts of input and output can be extended
according to user requirement.6.Large-screen LCD display: adopts
320 × 240 dot matrix large-screen high-resolution graphics LCD, all
the operation process are set on the display screen, display clear
and intuitive.7.Self-protection: adopts reasonable radiator
structure design, with a variety of reliable and comprehensive
protective measures and power soft start, and certain
self-diagnostic and interlock function.8.With separate dedicated DC
power output: dedicated adjustable 110V and 220V DC power
output9.Cost-effective: it's belonging to the cross-disciplinary
joint-design product, which integrated multi-disciplinary advanced
scientific and technological achievements. With high performance
