Symmetry

TB 9-6625-1966-24

NOTE

To measure TI, set start CHANNEL A slope switch to positive

and stop CHANNEL B slope switch to negative. Reverse slope

switches to measure T2.

(6) Set RANGE switch to X100.

(7) Measure T1 and T2 (fig. 1). If T1 does not equal T2 within 1 percent, perform b below.

b. Adjustments

NOTE

Due to interaction, if any adjustment is required all

adjustments must be completed.

NOTE

When TI SN prefix is 630 or higher, perform (1) through (10)

below. When TI SN prefix is 519, 533, 609, 616, or 622,

perform (11) through (15) below:

(1) Turn A13R24 (fig. 2) fully ccw.

(2) Set RANGE switch to X.1.

(3) Measure T1 and record value.

(4) Measure T2 while adjusting A13R22 (fig. 2) until T2 equals TI (R).

(5) Set RANGE switch to X100.

(6) Measure T1 and T2 and record both values.

(7) Adjust A13R23 (fig. 2) until T2 is midway between both values recorded in (6)

above (R).

(8) Measure T1 and T2 and record both values.

(9) Adjust A13R24 (fig. 2) until T2 is midway between both values recorded in (8)

above (R).

(10) Repeat (2) through (9) above for best in-tolerance condition.

(11) Set RANGE switch to X.1.

(12) Adjust R8 (fig. 2) until T2 equals T1 (R).

(13) Set RANGE switch to X100.

(14) Adjust R7 (fig. 2) until T2 equals T1 (R).

(15) Repeat (11) through (14) above for best in-tolerance condition.
