b. Adjustments
(1) With the appropriate current (5 percent of selected range) and 300 Hz frequency
applied, simultaneously press the (up) and (down) pushbuttons.
(2) After the TI indicates "190?", adjust calibrator to apply 95 percent of selected
range and 300 Hz frequency; simultaneously press the (up) and (down) pushbuttons.
After the TI indicates "doNE", the display will indicate the applied current 1 count (R).
13. dBm
a. Performance Check
NOTE
Place calibration enable jumper (located behind the front panel
display) in the upper position to NORM.
(1) Press dBm pushbutton.
(2) Connect calibrator to V/ /TEMP and LOW terminals.
(3) Select auto ranging.
(4) Adjust calibrator for 435.59 V at frequency of 50 Hz.
(5) TI will indicate within limits specified in first row of table 11.
(6) Repeat technique of (4) and (5) above for remaining dBm ranges in table 11. TI
will indicate within limits specified in table 11.
