Low Range Power Calibration
Press or key from the Frequency display to select “P-LO". Connect a variable resistor
as load and a calibrated true RMS Power Meter on one of the output socket and press
key in order to activate the CPU to read a low range offset power and send a
100VAC output voltage. The accurate RMS Power meter will indicate an actual power value
while the Current display on the AC Power Source will indicate a necessary value needed to be
calibrated. Adjust the load or voltage to get the reading from the RMS Power Meter to be
100.0W. By using the power value from the RMS Power Meter, press or key from the
Current display to scroll the display which indicates the power value, in order to set the power
according to the RMS Power Meter. After it is done, press to save the data stored and
the low range power calibration is completed.
High Range Power Calibration
Press or key from the Frequency display to select “P-HI". Connect a variable resistor
as load and a calibrated true RMS Power Meter on one of the output socket and press
key in order to activate the CPU to read a high range offset power and send a
100VAC output voltage. The accurate RMS Power Meter will indicate an actual power value
while the Current display on the AC Power Source will indicate a necessary value needed to be
calibrated. Adjust the load or voltage to get the reading from the power meter to be
suggestion value(500VA≦500W、1KVA≦1000W、2KVA≦2000W). Using the power value from
the RMS Power Meter, press or key from the Current display to scroll the display
which indicates the power value, in order to set the power according to the RMS Power Meter.
After it is done, press to save the data stored and the high range power calibration is
completed.
Each calibration items of the above is non-related to one another. If the calibration has to be
terminated half way, user can just press key to exit the calibration mode.
After the calibration is completed, turn OFF the AC Power Source.
