Figure 8-3: Normal state 
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 
key and the ENTER key to start the selected test.  For some of these tests, numeric data entry 
may be required to define the test number or the modulation rate.

This test will set the voltage and frequency to levels defined by Table 8-1.  The test will last for 30 
minutes.  The test will be repeated for the Group 2 and 3 using the Voltage setting from Table 8-2 
and the frequency from Table 9-1.  The   key (backspace) will terminate the test at any time.
