Product Description
1. Instrument working principle
RS2671 digital megohm meter consists of mid and large-scaled
integrated circuits. The instrument has large output power, high
short circuit current value and multiple output voltage levels
(four voltage levels). Working principle: the built-in battery, as
the power supply, generate DC high voltage through DC/DC
conversion, which reaches Pole L from Pole E through test object,
thus generating current from E to L; the current passes through I/V
conversion and measured insulation resistance value is directly
displayed on LCD after divider completes calculation.
2. Instrument application range
The instrument is a frequently-used and essential instrument for
electric power, post and telecommunication, communication,
mechanical and electrical installation, maintenance and industrial
enterprises and departments using power as industrial power or
energy. It is applicable to measure the resistance of various
insulating material, and insulation resistance of power
transformer, motor, cable, electric equipment, etc.
Feature/Function
This machine set possesses the following characteristics:
Large output power, strong load capacity and strong interference
resistance.
The enclosure of the instrument is made of high-strength aluminium
alloy, and the instrument is equipped with equipotential protection
ring and four-order active low-pass filter which can effectively
shield outside power frequency and strong electromagnetic field.
For measurement of capacitive test object, since output short
circuit current is larger than 1.6mA, it is quite easy to rapidly
increase measuring voltage to rated value of output voltage. For
low-resistance measurement, since it is designed by proportional
method, voltage drop does not influence measurement accuracy.
The instrument does not need manual operation, power is supplied by
batteries, and measurement range can be automatically converted.
Clear panel operation and LCD display make measurement quite
convenient and fast.
Output short circuit current of the instrument can be directly
measured, and it does not need loaded measurement for estimation.
