10A DC Resistance tester / Winding Resistance meter transformer dc resistance tester
I. Introduction
The DC resistance is the transformer’s semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project,the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation.
The DC Resistance transformer to meet fast measurement requirement, we developed HZ-3110B DC Resistance Tester. The instrument is a newpowerful technology, small size, light weight, high output current and other characteristics.
The device is controlled by the microcontroller, with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.
II. Safety Measure
1. Before using this equipment you must carefully read the manual.
2. The equipment operator should have electric general knowledge
3. Avoid putting the equipment in the contact of the rain, corrosive gas, dust, high temperature, direct sunlight, and other places.
4. Severe vibration has to be avoiding for gauges.
5. Only an expert must maintain and adjust the equipment
6. After the test, the user must wait till the discharge alarm stopped before switching off the device, and plugging off the test cables.
7. To measure no-load regulating transformers, the user has to wait till the discharge instructions alarm stops before switching stalls.
8. During testing, do not move the testing clamp and cables.
III. Configuration
1. Whole instrument controlled by high speed SCM, high automatic degree and simple operation.
2. The instrument adopts advanced power supply technology, with multiple current position, test range is wide, suitable for testing DC resistance of large and medium size transformer.
3. Has a complete circuit protection, reliable.
4.Discharge alarm, discharge indicator clear, reduces misuse.
5. Quick response speed, can be directly converted to load tap switch at measuring state, the instrument automatically refresh data.
6.Intelligent power management technology, instrument is always working at minimum power state, effective energy saving, reduce heat.
7.320 x240 matrix of ultra small pixel 65Ktrue color LCD.
8.With calendar clock and power storage, can store 1000 groups data, can be check at any time.
