b. Adjustments
(1) With the appropriate voltage (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% of selected range
and 300 Hz frequency then simultaneously press the
(up) and
(down) pushbuttons.
After the TI indicates "doNE" the display will indicate the applied voltage l count (R).
