Three-Channel DC Resistance Tester Manufacturer
Darui Electric recommends for you:
Basic Principle
The DC resistance tester adopts the typical four-wire measurement method to improve the accuracy of measuring resistance (especially low resistance). The programmable constant current source, programmable preamplifier, and A/D converter constitute the main body of the measurement circuit. The central control unit applies a constant, high-precision current to the external load under test by controlling the constant current source, and then processes the obtained data (including test voltage, current test current, etc.) to obtain the actual resistance value.
This instrument can store 255 test data and can print all stored test data. The stored data will not be lost when the instrument is reset or powered off.

Precautions
To ensure the safe and reliable operation of the instrument, please note the following:
1. For no-load tap-changing windings, it is not allowed to switch the no-load tap changer during the test or before the discharge is completed.
2. For inductive test objects, it is not allowed to remove the test leads before the discharge is completed (when the buzzer is sounding).
3. If the external AC220V power suddenly fails during the test, the instrument will start automatic discharge. At this time, it is not allowed to remove the test leads immediately; they can only be removed after 5 minutes.
