We are authorized distributor of SFL1500, SFL2500, SFL3000 of SFL Fault Locators designed by Sovtest ATE Ltd. Our company supplies these Cable Fault Locators after stringent testing in compliance with GOST R and also at the independent laboratories. Sovtest ATE Ltd produces the Locators as commercial equipments and the devices which are available at the finished-products storage area. The Fault Locator SFL operates on the basis of analogue signature analysis (ASA); sometimes this method is called VI (voltage – current).

The reference signature can be obtained from the workable (golden) module (the device has two channels) or from the album of reference signatures provided with the device. The device consists of its own memory with the capacity to store around 128 signatures and each signature is stored under certain number. Design variation with signatures stored in Flash or PC memory is also possible. RLC function is available on the device printed-circuit boards (component type recognition and rating definition function) for testing SMD components.

Advantages

• Test is done without working voltage supply on the board and the device sends safe level and frequency signals required for signature construction.


• The signature analysis allows defining of all types of elements - analog, digital, electromechanical, etc.


• Signature comparison is automatic.


• Difference limit (tolerance) is set by operator.


• Integrated functional generator allows workability appreciating of such important components as transistors, thyristors, optocouplers, etc. without unsoldering them out of the circuit and without damaging its printed circuit tracks. Generator has a step control of frequency (2 levels) and polarity, and also provides smooth adjustment of level and pulse duration.

Operational Modes:

Real-time mode (direct comparison): he device compares two equal units – reference unit and unit being tested. Result of the test is displayed on the PC monitor screen.

Rapid test mode: The device tests multi-terminal components (in general, connectors and IC) using multiplexer with 128 channels. In each channel, it sequentially scans the state of all outputs of the tested unit comparatively to GND, evaluating the coincidence/non-coincidence of the signatures in the given tolerance field.

Programming mode: The device checks the tested unit in compliance with set testing program. Operator sets probe following the program orders, and the device makes a comparison automatically. Reference signature file allows not using second (reference) unit during the test.
