3.5 Fixing output presetting
The unit includes VOLTAGE and CURRENT control knobs; in order
to make them mechanically
fi xed or semi- fi xed, guard caps are sup-
plied with the unit. Use them if output presetting is seldom necessary.
Using the guard caps
1. Check that the OUTPUT switch is turned off.
2. Turn on the POWER switch.
3. While pressing the LIMIT switch, preset the output level
(voltage and/or current) to a desired value. Here, a rough
presetting is acceptable.
4. Pull out the VOLTAGE and/or CURRENT control knob(s)
without turning it.
5. While pressing the LIMIT switch, use a fl at-head screw-
driver, and preset the output to a desired value.

To fi x presetting
6. Push in the guard cap, instead of the removed knob.
7. Press the LIMIT switch again to con
fi rm the presetting is
not changed.
■
To semi- fi x presetting
6. As shown in Fig.3-6, pierce the guard cap top with a Phil-
lips-head screwdriver.
7. Push in the guard cap, instead of the removed knob.
Since the guard cap is pierced, the output level may be readjusted
using a
fl at-head screwdriver.
• If you intend to re-install the knob, keep it in a safe place.
There is a metal fi tting inside the knob's bushing that engages
with the axis of a variable resistor (see Fig.3-7). Even when
you remove a knob, this metal
fi tting does not usually come
off the knob. However, if it does come off, place it inside the
knob's bushing.
