process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
name and item identification number as listed in table 2.
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturers' manuals and/or technical
manuals for the TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
e. Values enclosed within parenthesis apply to model 8020B.
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.
a. Remove protective cover from TI only to make adjustments and replace upon
completion.
b. Set ON - OFF switch to ON.
c. Set DC/AC pushbutton to DC (out) position.
d. Set function pushbutton to V (out) position.
8. Dc Voltage
a. Performance Check
(1) Connect TI V input to calibrator OUTPUT HI and TI COM input to calibrator
OUTPUT LO.
(2) Press TI 200 mV range pushbutton.
(3) Set calibrator for an output amplitude of 190 mV dc. If TI does not indicate
within limits specified in first row of table 3, perform b below.
