3.2.3 Circuit testing weighing pins for WI-5000-T/WI-5000-TS
Using a multimeter
Without a working weighing computer or connection box, you will be able to test the weighing pins using a
multimeter. This method is not fully reliable. A weighing pin may pass the test but still have a problem. For the best
results we recommend you test the weighing pins using a working weighing computer.
Only Regular DB + DA weighing pins are to be used for WIFO weighing equipment. Table 3.2.4 shows the resistance
between the various cores of the weighing pin. Replace the weighing pin if the measured value exceeds the 20%
tolerance margin as in table 3.2.4.
When using a multimeter, any defective weighing pins will usually give no reading at all, or a reading in excess of
twice the value as shown in table 3.2.4.

1. Weld the extension triangle in such a manner to the machine for weighing that the extension triangle can
still be easily attached and secured to the coupling triangle.
2. The machine for weighing must be put in the correct position before the weighing procedure. The extension
triangle must be in a perfect vertical position for the weighing procedure.
3.3.2 Instructions for replacing a weighing pin
Provide adequate support for the machine parts.
1. Disconnect the four wires of the weighing pin to be replaced from the wire box and put the connection cable
of the weighing pin through the three-point frame, so that the weighing pin and the connection cable can be
removed without causing damage.
2. Remove the bolts from the carrier frame. Make sure the attachment hole is clean and undamaged.
3. Mount the lower weighing pins with the arrow symbol pointing down and the upper weighing pin with the
arrow symbol pointing up.
4. Run the connection cable of the weighing pin in the correct manner and without causing damage through
the frame. The cable must not be shortened or get jammed under any circumstances.
5. Connect the four wires correctly in the wire box.
