NOTE
BEFORE CONNECTING TI, the protective earth terminal of
the instrument must be connected to the protective conductor
of the line power cord. The line plug shall only be inserted into
a socket outlet provided with a protective earth contact. The
protective action must not be negated by the use of an
extension cord (power cable) without a protective conductor
(grounding). Grounding one conductor of a two conductor
outlet is not sufficient protection.
NOTE
When indications specified in this procedure are not within
tolerance, perform the power supply check prior to making
adjustments.
a. Connect TI to 115 V ac power source.
b. Press power key to on and allow at least 30 minutes for TI to warm-up and stabilize.
a. Performance Check
NOTE
In the following procedure, any source can be connected either
to a sensor module (as written) or directly to the TI INPUT 50 Ω.
(1) Press TI BLUE key and then press TI INSTR PRESET key.
(2) Connect TI CALIBRATION AM/FM OUTPUT to TI sensor module.
(3) Press TI keys as listed in (a) and (b) below:
(a) MEASUREMENT AM.
(4) Allow TI to take at least two readings. If TI indication is not between 99 and
101 percent, perform b below.
(5) Press TI keys as listed in (a) and (b) below:
(a) DATA 2.2.
(b) DATA SPCL.
(6) Allow TI to take at least two readings and record this reading. If TI indication is
not between 99 and 101 percent, perform b below.
NOTE
Record indication in step (6) for future reference.
(7) Set the AM/FM test source TEST MODE switch to AM.
(8) Connect AM/FM test source AM OUTPUT to TI sensor module.
