4. Interface Description

 

In case of problems the following procedure should be followed:

1)  Turn off the power to the LCR-101

2)  Check the power input connections making sure that they are not reversed;

3)  Check the power supply complying with the specification;

4)  If the supply has a current limit, set this to 300mA;

5)  Make sure to install the LCR-101 in a environment without large area conductors nearby or mounting on a conductive surface. In self-test state, do not apply any tags inV468-W26’s functional area;

6)  Try to change the installment of the LCR-101 to another place to check if the trouble still exists.
