(4) Set calibrator output to minimum.
b. Adjustments (20/200 Model Only)
(1) Set the TI range to 200 V ac.
(2) Set the calibrator for a 190 V dc output.
(3) Turn VR (2) so that 190.0 is indicated on the LCD.
(4) No other adjustments can be made for DC voltage.
9. Ac Voltage
a. Performance Check
NOTE
For the 40/400 auto ranging meter for AC voltage (Defaults to
Lo): Lo: 0-39.99 V (Shifts to Mid at 40.00 V), Mid: 15.0-399.9 V
(Shifts to Lo at 14.9 V and to Hi at 400.0 V), Hi: 150-750 V
(Shifts to Mid at 149 V).
(1) Set TI function switch to AC/Ω and 20V; for the 40/400 auto ranging model set
TI function switch to ~ V. AC should be shown on the upper left corner of the display.
(2) Set calibrator output for the first value in table 4. TI will indicate within limits
perform b below.
(3) Repeat technique of (2) above for the remaining settings and indications listed in
