(3) Set TI NULL switch successively to each more sensitive position while adjusting
R503 (fig. 1) for null indication on TI (R).
14. Supply Voltage
a. Performance Check
NOTE
Do not perform supply voltage check if all other parameters are
within tolerance.
(1) Connect multimeter between side of C219(+) and negative side of C215(-) (fig. 1). If
multimeter indication is not -18.0 (0.1) V perform b (l) below.
(2) Connect multimeter between negative side of C518(-) and positive side of
R538(+) (fig. 1). If multimeter indication is not +18.0 (0.1) V perform b (2) below.
b. Adjustments
(1) Adjust R111 (fig. 1) for a -18.0 V indication on multimeter (R).
(2) Adjust R539 (fig. 1) for a +18.0 V indication on multimeter (R).
15. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
CALIBRATION PROCESS FOR VOLTAGE DIVIDER
FLUKE MODEL 80E-10
16. Preliminary Instructions
a. The instructions outlined in paragraphs 16 and 17 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 results 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 for this TI.
d. Unless otherwise specified, all controls and control settings refer to the TI.
