HIGH VOLTAGE is used or exposed during the performance of
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUTS(S) to minimum after each step within the
performance check where applicable.
b. Connect autotransformer to a 115 V ac source and adjust for a 115 V ac output.
c. Set LINE switch to ON and allow 30 minutes for TI to warm-up and stabilize.
CAUTION
To avoid damage to meter, set range calibrator FUNCTION
switch to STANDBY while changing RANGE switch settings
NOTE
If an out-of-tolerance indication is obtained during any
performance check, re-zero TI as follows: Set range calibrator
FUNCTION switch to STANDBY, then press TI ZERO
(model 435A) switch and wait for meter zero indication (model
435A) to stabilize.
8. Zero Carryover (Models 435A, 435B, 435BOPT001, and 435BE21)
a. Performance Check
(1) Connect multimeter to RECORDER OUTPUT (rear panel).
(2) Connect power sensor using power sensor cable (p/o TI).
(3) Set switches as listed in (a) through (c) below:
(a) CAL FACTOR % to 100.
(b) POWER REF to OFF (out) (rear panel).
(c) RANGE to 3 W.
(4) Press ZERO pushbutton and wait for meter indicators position to stabilize.
Multimeter will indicate between -0.9 and +0.9 mV dc. Release ZERO pushbutton;
multimeter will indicate between -15 and +15 mV dc.
(5) Set RANGE switch as listed in table 4.
Multimeter will indicate within
limits specified.
