WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
a. Connect adapter cable W100, supplied with TI, to J100 connector; then connect
electric connector assembly to the other end of adapter cable.
b. Connect power cable to the power connector and to a 115 ac power source.
c. Set POWER switch to A.C.
8. Continuity
a. Performance Check
(1) Set the FUNCTION switch to CONT. P.
(2) Set the CABLE LENGTH switch to 250.
(3) Set AUTO/SINGLE switch to SINGLE.
(4) Press the RESET pushbutton.
(5) Set resistance standard No. 2 for 20.4
and connect between pins 1A and 1B
(fig. 1) of the electric connector assembly (connected to end of adapter cable).
(6) Press the ADVANCE pushbutton once to test circuit 01. TI TEST light and
FAULT light will be on; if not, perform b below.
.
(7) Press the RESET pushbutton and set resistance standard No. 2 for 19.6
(8) Press the ADVANCE pushbutton once to test circuit 01. TI FAULT light will
remain off; if not, perform b below.
(9) Press the RESET pushbutton.
b. Adjustments
(1) Set POWER switch to OFF and disconnect power cable from ac power source.
(2) Remove TI from its casing. Remove the end plate (located near the interface
connector J100). Ensure that potentiometers R1, R2, and R3 and the test points TP1, TP2,
and TP3, located on A3 measurement card, are readily accessible (fig. 1).
(3) Reconnect TI to ac source and set POWER switch to A.C.
