Display Screen 1
Display screen 1:
Displays the measured impedance in ohms 107, phase angle in degrees 66
°
, and the
frequency of the winding test, 200 Hz. The screen number (1) is displayed in the upper left hand corner.
Display Screen 2:
Displays the results of the Current Frequency (I/F) response test (-45), (
the current at
400 Hz is 45% lower than the current at 200 Hz).
The doubled test frequency is displayed in the lower
right hand corner; screen number (2) is displayed in the upper left hand corner. Note: The 16% shown
in upper right corner is the change in phase angle when the test frequency is doubled. Not used for
analysis purposes.
1.
To return to the Display Screen 1 Press the TEST key again, this displays the impedance and
phase angle measurement.
2.
Record the measured values on the Motor Test Form.
ERROR CODES
If the impedance readings are out of range an error code will be displayed on the measurement screen.
·
E1 error code means the impedance value is greater than 1000 ohms.
·
E2 error code means the impedance value is greater than 10,000 ohms.
