WARNING
HIGH VOLTAGE is used or exposed during the performance of
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
a. Mechanically zero TI meter.
b. Connect RF probe to PROBE jack.
NOTE
The RF probe authorized for use with TI must have serial
numbers matching the TI serial numbers. If a new RF probe is
calibrated with TI, annotate new RF probe with TI serial
number. Do not use any RF probe not calibrated with TI.
c. Connect TI to a 115 V ac source.
d. Set OFF-ON switch to ON.
e. Set RANGE switch to .001 VOLTS.
f. Replace TI RF probe tip with test adapter (50
feedthrough termination).
g. Adjust ZERO control for TI indication of 0.
NOTE
If noise is present, adjust ZERO control for an average TI
indication of 0.
h. Replace test adapter (50
feedthrough termination) with TI RF probe tip.
i. Allow TI to warm-up for 5 minutes.
j.
Allow measuring receiver to warm-up for 30 minutes.
NOTE
Ensure proper calibration factors are used for measuring
receiver sensor module selected.
8. Accuracy and Linearity
a. Performance Check
(1) Set calibrator for wideband operation.
(2) Connect calibrator WIDEBAND OUTPUT (without 50 ohm pad) to TI RF probe
using 50 ohm feedthrough termination supplied with TI.
(3) Adjust calibrator frequency controls for 50 kHz output.
