(8) Adjust the calibrator for 190.00 A dc. If TI does not indicate within limits
specified in first row of table 8, perform b (2) below.

b. Adjustments
(1) Simultaneously press the
(up) and
(down) pushbuttons.
After the TI
indicates "doNE", the display will indicate zero l count.
(2) With the appropriate current (determined by the select range) applied,
simultaneously press the (up) or (down) pushbuttons. After the TI indicates "doNE",
the display will indicate the applied current 1 count (R).
11. Ac Volts
a. Performance Check
NOTE
Do not exceed 1000 V peak or 500 V rms between the input
V/ /TEMP and LOW terminals or instrument damage may
occur.
(1) Press ACV pushbutton.
(2) Connect TI V/ /TEMP and LOW terminals to the calibrator HI and LO
output terminals.
(3) Press
(up) or
(down) pushbutton to select the 200 mV range.
(4) Adjust the calibrator for 10.000 mV at 20 Hz. If TI does not indicate within
limits specified in first row of table 9, perform b below.
(5) Repeat technique of (3) and (4) above for voltages and settings in table 9. If TI
does not indicate within limits specified in table 9, perform b below.
