While going through the setting up procedure everything was going as it should until section "(t) Set the mA/V switch to Cal" the meter needle remains on the zero point on all positions of the mA/V switch. I have checked the meter and it is functioning perfectly. Is there any obvious reason why this is happening? Though it worthwhile to ask before dismantling it to check the amplifier board.
