a. Performance Check
NOTE
Do not exceed 1000 V peak between the input V/ /TEMP and
LOW terminals or instrument damage may occur.
(1) Press DCV pushbutton.
(2) Short the LOW and V/ /TEMP terminals with a lead.
(3) Select the 200 mV range by pressing the
(up) or
(down) pushbutton.
(4) If TI does not indicate within limits specified in first row of table 3, perform
b (l) below.
(5) Repeat technique of (3) and (4) above for remaining TI ranges. If TI does not
indicate within limits specified in table 3, perform b (l) below.

(6) Disconnect short connect TI V/ /TEMP and LOW terminals to the calibrator
HI and LO output terminals.
(7) Press
(up) or
(down) pushbuttons to select the 200 mV range.
(8) Adjust the calibrator for 190.00 mV dc. If TI does not indicate within limits
specified in first row of table 4, perform b (2) below.
(9) Repeat technique of (7) and (8) above for voltages and settings listed in table 4.
If TI does not indicate within limits specified in table 4, perform b (2) below.
