(3) Adjust TI LRC dial AMP GAIN, OSC GAIN, Q and D-Q dial for best null on
electron ray tube. If capacitance standard is not furnished with a test report, final LRC
dial setting will be between 9.949 and 10.051. If capacitance standard is furnished with
test report, measured value will be within 0.5 percent + 1 division on LRC inner dial of
test report value.
b. Adjustments. No adjustments can be made.
13. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
CALIBRATION PROCESS FOR ESI, MODEL 250DE
14. Preliminary instructions
a. The instructions outlined in paragraphs 14 and 15 are preparatory to the calibration
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 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 manufacturer's manual for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
15. Equipment Setup
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.
NOTE
Some TI's are operated by 115 V ac and some are battery
operated. Make power connections accordingly.
a. If required, connect TI to a 115 V ac power source.
b. Turn DET GAIN control cw out of PWR OFF position.
c. Set GEN DET switch to DC DET-DC EXT GEN.
