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-3140A DC Resistance Tester. The instrument is a new powerful 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.
