How do I align my meter on my TLA-100A?

In Output mode, you'll need to contact us for the alignment procedure. In Reduction mode, take off the top of the unit and warm up completely. BE VERY CAREFUL AND TOUCH NOTHING ON THE INSIDE OF THE UNIT; POTENTIALLY LETHAL VOLTAGES INSIDE. EVEN WITHOUT POWER CONNECTED CAPACITORS WILL STORE A CHARGE THAT CAN SHOCK AND POTENTIALLY KILL. If you are unfamiliar with doing this, please have a qualified service technician do this for you. Set the meter select switch to Reduction. With a small, flathead screwdriver, adjust R53 towards the back, left side of the main board until the meter rests at 0. It is helpful to switch back and forth from Output to Reduction to make sure the meter sits in the proper position.
