Setting the switching interval
You can set the switching interval by specifying a frequency and duty ratio or by specifying an
amount of time.
■
Setting the switching interval by specifying a frequency and duty ratio
Set the frequency and the duty ratio (the ratio of HIGH to LOW). It does not matter whether
you set the frequency or the duty ratio first. In the following example, the frequency will be set
first.
1
Press FREQ/DUTY until “FREQ” is highlighted.
The FREQ/DUTY key lights, and the frequency can be set. Pressing FREQ/DUTY
switches between “FREQ” and “DUTY.”
2
Turn the rotary knob to set the frequency (1 Hz to 50 kHz).
The frequency setting resolution varies depending on the specified frequency. The
PLZ-4WL switches between units (Hz and kHz) automatically.
3
Press FREQ/DUTY to highlight “DUTY.”
The FREQ/DUTY key lights, and the duty ratio can be set.
4
Turn the rotary knob to set the duty ratio (5 % to 95 %).
The minimum time interval is 10 μs. The maximum duty ratio is limited as the
frequency gets higher.
■
Setting the switching interval using two (HIGH and LOW) operation times
(Th and TL)
Set the HIGH and LOW times. It does not matter whether you set the HIGH or LOW time first.
In the following example, the HIGH time will be set first.
1
Press Th/TL (SHIFT+FREQ/DUTY) until “Th” is highlighted.
The Th/TL key lights, and the HIGH time can be set. Pressing Th/TL (SHIFT+FREQ/
DUTY) switches between “Th” and “TL.”
2
Turn the rotary knob to set the HIGH time.
3
Press Th/TL (SHIFT+FREQ/DUTY) to highlight “TL.”
The Th/TL key lights, and the LOW time can be set.
4
Turn the rotary knob to set the LOW time.
Turning the switching function on and off
After you finish setting the switching level and the switching interval, turn on the switching
function.
If you press SW ON when the switching function is off, the switching function will turn on, and
the SW ON key will light.
If you press SW ON when the switching function is on, the switching function will turn off, and
the SW ON key light will also turn off.
Memo
When you set Th, the fine
adjustment setting
resolution is 50 times that
of coarse adjustment.
