7. Equipment Setup
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.
CAUTION
To prevent possible damage to the TI, turn off the power
module before installing or removing the instrument. Do not
use excessive force to install or remove.
NOTE
The TI must have the output leveling head installed before use.
The leveling head is calibrated to match TI and tagged with
serial number of generator to be calibrated. The two cables
from the leveling head connect to the two OUTPUT HEAD
connectors on the lower right portion of TI. If either of these
two cables is disconnected, the TI output will be automatically
turned off. The leveling head must be used for all operations
and should be connected directly to the load to maximize
performance unless otherwise indicated.
