advance to the next parameter. The range is 0 to 999.9 seconds, if the Timer is set to 0,
the instrument will operate in a continuous ON mode when the test button is depressed
and released. It will stop when the DUT (Device Under Test) goes into failure or the
manual reset button is pressed.
4. Frequency Setting
Please press the SET key until arriving at the Frequency setting. The display will show:
Freq = 50 HZ
or Freq = 60 HZ
Use the Up (
∧
) or Down (
∨
) arrow keys to change the Frequency setting to 50Hz or 60Hz,
then press the EXIT key to store the frequency setting and return to the Run mode, or
