ALIGNMENT PROCEDURE (C<strong>372</strong>)<br />
I. INITIAL ADJUSTMENT (No load connected)<br />
A. OUTPUT OFFSET VOLTAGE<br />
1. Connect a DC Millivoltmeter between TP303 & TP304 (pin 1 of IC 301A & gnd),<br />
then adjust VR303(50kohms) to get a reading as close as 0V as possible, +/-3V.<br />
2. Connect a DC Millivoltmeter between TP403 & TP404 (pin 1 of IC 401A & gnd),<br />
then adjust VR401(50kohms) to get a reading as close as 0V as possible, +/-3V.<br />
B. IDLING CURRENT<br />
1. Connect a DC Millivoltmeter to TP301 and TP302, then adjust VR302 (500ohms)<br />
for 5-6mV reading on meter.<br />
2. Connect a DC Millivoltmeter to TP401 and TP402, then adjust VR402 (500ohms)<br />
for 5-6mV reading on meter.<br />
3. Leave power “ON” for a minimum of 5 minutes.<br />
C. ISC SENSITIVITY<br />
Connect a DC Millivoltmeter to TP701 and TP702, then adjust VR701 (47kohms)<br />
between –50mV to -100mV.<br />
II. FINAL ADJUSTMENT<br />
Repeat procedure A and B for offset voltage and idling current alignment respectively.<br />
