CHAPTER 4. MANUAL OPERATION
4.1 Manual Operation
1. Setting Of Output Voltage
High range voltage can be set between 0 - 310V while low range voltage is 0-155V under
AC mode. Press and hold the
or
key will firstly clear the decimal number of
setting to zero. Subsequently, every 0.3 seconds will change a step and thereafter a first
integer of setting number will vary and then to the second integer and third integer of the
voltage setting respectively. For the third integer, it takes 0.1 seconds only to vary every
step in order to speed up the scrolling.

If the voltage is adjusted when the
indicator is ON, the AC Power Source will
generate the output voltage accordingly.
When the voltage display is blinking, the output
voltage remains the same as the previous set voltage. After 2 second the voltage display
will stop blinking and the new set voltage is accepted. Any invalid setting may not be
accepted.
2. Setting Of Output Frequency
For frequency setting in the range of 40-99.9 Hz, each change on the setting are
0.1Hz/step for normal setting and 1Hz/step for coarse setting. In 100-450 Hz range, each
change on the setting are 1Hz/step for normal setting and 10Hz/step for coarse setting. As
the 50 Hz or 60 Hz key is pressed, the desired frequency will be immediately updated. (The
same method applied like voltage setting to scroll the display).
3. Setting Of Voltage Range
If the desired voltage is lower than 155 V, press the HI / LO Key first. The LO LED is lighted
to indicate the AC source is in 0 - 155 Volt range and allow a higher range of current limit.
For the 0 - 310V of voltage range, the range of current limit drops to half as comparing the
current limit at the 0 - 155V range (Refer to the specification table). Setting of voltage
range may not influence the existing output voltage setting. Anyhow, changing the voltage
range during the
indicator is ON will lead to the output voltage cutoff (about 20
ms) and this should be avoided if possible.
4. Setting Of Current
While the OUTPUT is not activated, pressing the
or
key will enter to the setting
mode of low-limit current. Press further
or
key to continue scrolling the display
in order to change the current limit. If the setting is hold for 2 seconds, it will return to a
standby mode from current setting mode. Meanwhile, at the standby mode, the output
capacity (Refer to the specification table) limits the output current or allows setting the
low limit current. The AC Power Source cuts off the output immediately when the actual
current has exceeded the limits and a HI-A error message is shown. Any invalid current
setting will not be accepted
