(2) Set the calibrator to output 55.000 V ac at 6 kHz. Allow the circuit to stabilize
for 2 minutes.
(3) Select and activate OK. The TI will measure the voltage. The Aligning field will
show that the alignment is started as shown in figure 17.
Figure 17. Vpri Alignment First Voltage.
(4) When the measurement is completed, a second on-screen instruction is
displayed. Set the calibrator to apply 40.000 V ac at 6 kHz.
(5) When both the voltage measurements are complete, the TI will calculate the
alignment constants. When the alignment progress bar shows 100%, the TI will enter a live-
reading performance check mode.
(6) Press the TI ETTS BrainPak left Encoder knob to save the alignment
constants.

Performance Check
(1) Select and activate Ipri from the Circuit menu on the UxValidator. Ipri will
appear in the Circuit field.
(2)
Connect calibrator to TI ETTS Pod as shown in figure 18.
(3)
Select and activate Test from the POD Alignment screen on the UxValidator.
(4) Set the calibrator to output 0.440 A at 6 kHz. If TI reading on UxValidator does
not indicate between 0.435 and 0.445 A ac, perform b below.
(5) Set the calibrator to output 0.460 A at 6 kHz. If TI reading does not indicate
between 0.455 and 0.465 A ac, perform b below.
(6) Set the calibrator to output 0.480 A at 6 kHz. If TI reading does not indicate
between 0.475 and 0.485 A ac, perform b below.
(7) Press the TI ETTS BrainPak left Encoder button to return to the main POD
Alignment screen.
(8)
Turn calibrator output to Standby.
