b. Adjustments
NOTE
For serial number prefix below 1444A, no adjustments can be
made. For serial number prefix 1444A and above, perform (1)
through (4) below.
(1) Remove bottom cover from TI.
(2) Adjust function generator for 100 kHz and amplitude of 25 mV.
(3) Adjust A1 R59 (A channel) closest to front panel or A1 R57 (B channel) near rear
of TI to obtain stable indication of applied frequency.
(4) While reducing function generator amplitude, adjust A1 R59 (A channel) or A1 R57
(B channel) to obtain maximum sensitivity.
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
