1. Remove the LCT-601 from the case with four screws.
2. Locate the group of jumpers and remove all jumpers.
3. Using a capacitance meter, measure the capacitance from 1 - 1 and verify 15 nF ± 5%.
Replace if outside this tolerance.:_______
4. Using an ohmmeter, measure the resistance from 2 - 2 and adjust the potentiometer to
achieve a value of 10kohm ± 1%: _______
5. Using an ohmmeter, measure the resistance from 3 - 3 and adjust the potentiometer to
achieve a value of 1kohm ± 1%: _______
6.
