3. Operation
1.Voltage Setting:
Voltage setting contents ‘110V ’, “ 220V ’, ‘▲’ and ‘▼’ four keys.
a. When any one of the keys mentioned above is pressed, the voltage
display will flash one time, the APS9301/9501/9102 will go to the
setting mode and show the voltage setting value.
b. If the ‘110V’ Key is pressed, the output voltage will be adjusted to
110V immediately. Meanwhile, the voltage display will switch back
to the reading mode automatically.
c. If the ‘220V’ key is pressed for 0.2 seconds continuously ( for safety
reason, must be), the output voltage will be adjusted to 220V.
Meanwhile, the voltage display will switch back to the reading mode
automatically.
Note: It would not work if the output voltage is setting on low range.
(0~150V output)
d. If either “▲” or “▼”key is pressed for 0.5 seconds continuously, the
output voltage will be adjusted. If either “▲” or “▼” is pressed twice
continuously, the output voltage will be adjusted immediately.
e. The adjusting rates are 0.1V/step on fine adjust mode and 1V/step on
coarse adjust mode.
f. The first six steps of adjustment will be spent 0.25 seconds per step. If
the key “▲” or “▼” is pressed continuously, it will spend 0.13 second
per step for the rest steps. If the key is released, the voltage
adjustment would be stopped and go back to the original adjustment
speed (0.25 seconds per step) automatically.
g. If the output mode is setting ON ( the indicator ‘OUTPUT’ would light),
the output voltage could follow the setting voltage simultaneously
Caution: When you adjust the voltage at “▲” or “▼” mode, it is
better to switch off the output to avoid unnecessary damage
because of accidental voltage adjustment.

h. If any key mentioned above is not pressed for 2 seconds continuously,
APS-9301/9501/9102 would go back to the normal operation and
the voltage display could show the reading value automatically.
2.Frequency Setting:
Frequency setting contents ‘50Hz’, ‘60Hz’, ‘▲’ and ‘▼’ four keys.
a. Either the key ‘50Hz’ or the key ‘60Hz’ is pressed, the frequency will be
changed immediately to 50Hz, 60Hz respectively. Meanwhile the
output frequency will be changed coincidentally.
b. The frequency ranges from 45Hz to 99.9Hz can be adjusted by 0.1 Hz
per step in fine adjustment mode and 1 Hz per step in coarse adjustment
mode. The frequency ranges from 100Hz to 500Hz can be adjusted by 1
Hz per step in fine adjustment and 10Hz per second in coarse
adjustment mode.
c. The other setting are same as voltage setting.
3.High / Low Voltage range selection:
Press the key of ‘RANGE’, if the indicator lights, the output voltage
would be setting on the high voltage range, otherwise, the system
would be setting on low voltage range. The changed range would not
cause the setting voltage to change, however, there is a 20ms
interruption during the voltage range changing. The non-reasonable
range changing (For example, the voltage sets 200V but the range is
changed to the low range) is not acceptable by APS-9301/9501/9102.
Note: High range voltage 0 ~ 300V
Low range voltage 0 ~ 150V
4.Instrumentation selection:
a. Press the key of ‘A’, the indicator of current will light and the LED
display will show the value of current.
b. Press the key of ‘W’, the indicator of power will light and the LED
display will show the value of wattage.
c. Press the key of ‘PF’, the indicator of power factor will light and the
LED display will show the value of power factor.
