(5) Place the 100-ohm, ±1 percent, ½-watt

resistor between the E and B jacks on the front panel.

(6) Adjust resistor R30 so that meter Mlindi-

cates 100 ohms.

(7) Remove the 100-ohm resistor, and check to

see that the meter pointer indicates full scale. If the

meter pointer does not indicate full scale, repeat the

procedures in (2) through (6) above.

a. Test Equipment Required. An ME-30(*) /U is

required.

b. Procedure.

(1) Disconnect the unit from the case by remov-

ing the four panel screws.

(2) Set the polarity switch to FWD PNP.

(3) Set the function switch to F.E.T. CAL.

(4) Place the ME-30(*)/U across the E and B

jacks on the front panel.

(5) Adjust CAL control R5 (fig. 7-2) and resis-

tor R23 (fig. 71 ) so that the meter pointer indicates

full scale when the ME-30(*)/U indicates 100 mv.
