(3) Adjust power meter calibrator ZERO control for multimeter indication between
0.998 and 1.002 V dc (0.999 and 1.001 V dc for model 432B).
(4) Set CALIBRATION FACTOR switch to positions listed in table 4. Multimeter
will indicate within limits specified.
(5) Repeat (3) above.
(6) Set power meter calibrator ZERO/TEST switch to ZERO and POWER switch
to .01 mW.
(7) Set TI RANGE switch to .01 mW (10 μW for model 432B).
(8) Adjust power meter calibrator ZERO control for multimeter indication between
-2 and +2 mV dc.
(9) Set power meter calibrator ZERO/TEST switch to TEST.
b. Adjustments. No adjustments can be made.

10. Meter Linearity Test
a. Performance Check
(1) Set RANGE switch to 3 mW (10 mW for model 432B).
(2) Set power meter calibrator POWER (mW) switch to 1. TI meter will indicate
between 0.97 and 1.03 mW (0.95 and 1.05 mW for model 432B).
(3) Set power meter calibrator POWER (mW) switch to 2. TI meter will indicate
between 1.97 and 2.03 mW (1.95 and 2.05 mW for model 432B).
(4) Set power meter calibrator POWER (mW) switch to 3. TI meter will indicate
between 2.97 and 3.03 mW (2.95 and 3.05 mW for model 432B).
b. Adjustments. No adjustments can be made.
