(30) Set calibrator output to 190.000 V.
(31) Press TI STO/CLR and RCL buttons as necessary for a TI display of 190.000.
(32) Change calibrator output to minimum and disconnect calibrator OUTPUT HI
and LO from TI INPUT HI and LO.
(33) Press TI 1000 range pushbutton (in position).
(34) Short TI INPUT HI and LO terminals.
(35) Press TI REL pushbutton and ensure TI REL annunciator is displayed.
(36) Remove short at TI INPUT HI and LO terminals.
(37) Connect calibrator OUTPUT HI to TI INPUT HI and calibrator OUTPUT LO
to TI INPUT LO.
(38) Set calibrator output to 1000.00 V.
(39) Press TI STO/CLR and RCL buttons as necessary for a TI display of 1000.00.
(40) Change calibrator output to minimum and disconnect calibrator OUTPUT HI
and LO from TI INPUT HI and LO.
NOTE
The following steps will store calibration constants.
(41) Press TI REL and dB pushbuttons simultaneously and ensure TI STOR
annunciator is displayed.
(42) Set CALIBRATION switch on TI rear panel to DISABLED.
9. AC Voltage
a. Performance Check
(1) Set TI pushbuttons as listed in (a) through (c) below:
(a) AC DC to AC (in position).
(b) REL to off.
(c) Range 200m (in position).
(2) Set calibrator for an output of 190.00 mV at a frequency of 20 Hz. If TI does not
indicate within limits specified in first row of table 4, perform b below.
(3) Repeat technique of (1) and (2) above for remaining calibrator outputs and TI
b below.
