JYR 10S is a highly engineered DC resistance tester and a fully automated, digital portable measuring instrument developed using a number of patented technologies.

This instrument is not only suitable for power distribution transformers, transformers, electrodetaciators, electromagnetic operating mechanisms and other inductive test products, but also for wire, switch contacts, relay contacts and other impedance test products measurement.

For dry transformers, amorphous alloy transformers, because the low-voltage coil is made of copper foil, the resistance value is very low, for which the instrument increases the current to 10A, to solve the problem of low-value resistance measurement. At the same time, for high-resistance test products such as transformers, the instrument also extended the range to 100KΩ.

The instrument is powered by a rechargeable lithium-ion battery, using advanced power management technology to measure hundreds of transformers on a single charge.

Function Introduction.

A tooled product for transformer DC resistance testing.With insulated shell, sealed, Anti-leakage, wind and sand; four-corner with soft rubber for shock absorption protection.
l Suitable for transformers, transformers, motors and other inductive test products resistance measurement, but also suitable for copper row, wires, switch contacts and other resistance test product resistance measurement.
l The windings of Yn, Y, D and other connections can be automatically tested with three-phase simultaneously, automatic phase change, automatically determine data stability, and calculating the three-phase imbalance rate.
l 7-gear current output, optional 10A, 3A, 1A, 300mA, 100mA, 20mA and automatic. Automatic currents cover full-scale testing and maximum output currents up to 10A.
l Test the resistance range 0Ω-100KΩ.
l With temperature conversion function. Select the test material (copper/aluminum) and input the temperature (optional special wireless temperature probe to collect the test temperature directly),then automatically convert to the resistance at the set standard temperature for easy comparison with historical data.
l 1 00 sets of test data can be stored;With USB interface to import data into the USB drive;With the built-in Bluetooth communication module to interact with PC and other computer data or connect to a micro-Bluetooth printer to print data reports.
l The "Test/Stop" mechanical button with shortcuts and automatic shutdown function if no operating in 5 minutes.
l Built-in rechargeable lithium battery, a single charge can complete a hundred of transformer tests.Fully balanced battery charging technology effectively extends battery life.
l With high-brightness color touch LCD display, touch menu operation is fast and clear.
l With discharge sound alarm, overheat alarm and other perfect protection circuit. Clear instructions to reduce mishandling.
