5.4 Enabling the test
Figure 4: Test Enable switch and indicator
The selected test mode is enabled by pressing the Start Test switch
and the
indicator displays the running test status.
5.5 Test Supply Indicators
The HFG02 monitors the input from the Test Supply under test and displays the
voltage and frequency measurements on the front panel indicators as shown in
Table 2.
Test Supply monitoring is continuous and automatic, and does not require a test
mode to be enabled. Tests are automatically disabled if the Test Supply voltage or
frequency are outside their permitted ranges.
