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 checks where applicable.
a. Remove protective cover from TI as necessary to gain access to adjustments.
b. For some checks throughout this procedure, it may be necessary to manually set TI
range by pressing RANGE pushbutton.
