9809 wire tester manual:
1. Applicable
9809 wire tester is suitable for detecting electrical defects in the production process of electronic cable products such as terminal wires, USB, computer peripheral wires, and flat cables.
It can quickly detect electrical characteristics such as short circuit, open circuit, and dislocation of the wire harness. It is the latest fast and economical wire harness testing machine instrument.
2. Technical specifications
1. Working voltage: ACV220+/-10% 50HZ instrument can work continuously
2. Test point: up to 80P (A, B terminals)
3. Operating Instructions
1. Connect the power supply, and turn on the power switch on the back, the power indicator light is on, and READ DATA appears on the instrument screen? PUTCABLE ON (do you want to learn? The wire is empty)
2. Insert the 40P cable at the A and B ends, and connect the test fixture of the wire to be tested;
3. Insert the wires to be tested into the A and B terminals respectively, and confirm that the connection is good;
4. Press the "read button" after learning, press the "read button" again to view the connection information, the screen shows LINE, A: * TO B: *, each time you press the "read" button That is, only one set of wiring data can be viewed until it is finished;
5. After the reading line is correct, pull down the wire and start the test. The instrument does not need to repeat the "read" key during continuous testing, and the test can be performed automatically. When "PASS" appears on the screen and "beep" sounds, it means good product'
6. If there is a short circuit or open circuit during the test, the screen will display "ERROR: OPEN, A: ** B: **" error red light is on, and any sound will appear at the same time, indicating that the wire is a defective product (OPEN means open circuit, SHORT means short circuit, LOCATION means dislocation)
5. Matters needing attention
1. This instrument is suitable for standard testing (that is, there are terminal wires at A and B terminals)
2. When there is an abnormality in the test, you can use the probe to find a point to check whether the fixture is intact
3. The instrument must be clean and hygienic, and the operating table is clean and tidy. In case of a sudden power failure, the power switch should be turned off in time, and the power switch should be turned on again after the call
4. In case of failure of the setting, the technical service department of our company must be notified in time, and it is not allowed to start the machine for maintenance without authorization.
