Warning: The power supply provides a three-wire power cord; you should plug it
to a three cord junction box. You should also make sure the power supply is
well grounded.
Warning: The connection wire should have enough current capacity that it can
bear the max rated current/short current of the power supply and not get
too hot.
Warning: To avoid any fire or electric shock, please ensure the AC input voltage
fluctuation not exceed 10% of the working voltage range.
Note: In some situation, use the mis-configured main voltage for the instrument may
cause the main fuse blew.
Note: If the power supply is used to charge a battery, please pay attention to the
positive and negative polarity to avoid any damage.
After power up, the instrument will automatically perform a self test routine. If the power
supply doesn't work, then refer to section 1.2.5.

Followed by
10.00V
0.000A
The first row displays the voltage value for the three channels; the second row displays the
current value or the output OFF state.
About 1S later, if EEPROM was damaged, then the VFD will display (about 2S):
