The DO160 NORMAL 1 and NORMAL 2 screens have the following tests:
1 VOLT FREQ MIN
2 VOLT FREQ MAX
3 VOLT UNBALANCE
4 WAVEFORM DISTORTION
5 VOLT MODULATION
6 FREQ MODULATION
7 POWER INTERRUPT
8 VOLTAGE SURGE
9 FREQ TRANSIENT (group 1)
FREQ VARIATION (group 2 & 3)
The above tests can be selected by scrolling to the highlighted selection using the up and down
