7.6.7.9
Turn the clamp so that to place the marking plate in upper
position and repeat the measurements.
7.6.7.10 Turn off all clamps.
7.6.7.11 Make parallel connection of the outer voltage of the system
to the terminals of reference and measurement channels of voltage. Set the
output voltage of UPPU-1M system on 100 V. Measure the phase shift.
7.6.7.12 Change places of the wires of one of the channels and re-
peat the measurements.
7.6.7.13 VAF is considered to pass the tests if the range of voltage-
current, current-current, voltage-voltage phase shift is between –180 and
+180 and the permissible reduced error doesn’t exceed the value determined
in p. 7.1.
7.6.8 Verification of effective range and measurement error of fre-
quency measurement.
7.6.8.1
Set the output voltage of UPPU-1M system on 100 – 400
V. Set the frequency of outer signal on 45 Hz. Measure the frequency. Re-
peat measurements at the following frequencies: 50, 55, 60, 65 Hz.
7.6.8.2
VAF is considered to pass the tests if the range of effective
value of alternating voltage frequency is 45-65 Hz and the relative permissi-
ble error doesn’t exceed the value determined in p. 7.1.
7.7
