(4) Set TI RANGE switch to 1 mW.
(5) Adjust TI (front panel) CAL ADJ for a 1000 2 mV dc indication on multimeter.
Verify that TI meter indication is between 0.99 and 1.01; if not, perform b (1) below.
(6) Set TI and range calibrator RANGE switches to 3 W. If multimeter does not
indicate between 975 and 1,025 mV dc, perform b (2) through (20) below.
(7) Set TI and range calibrator RANGE switch to positions listed in table 6. TI and
Table 6. Instrument Accuracy (Model 435A, 435B, 435BOPT001, and 435BE21)

b. Adjustments
(1) Adjust A4R35 (fig. 2) for a 1 V indication on TI meter.
(2) Set TI LINE switch to OFF. If TI meter does not indicate 0 (zero), adjust to 0
using adjustment screw located below meter face.
(3) Set switches as listed in (a) through (d) below:
(a) CAL FACTOR % to 100.
(b) RANGE to 100 mW.
(c) POWER REF (rear panel) to OFF.
(d) LINE to ON.
