z I SET : Output current setting
The minimum resolution of output current is at 1mA(output≧10A at
10mA). When set output to ON, press [I SET] to proceed current setting,
the meter will display measurement value (the symbol of “＊” is on with
blinking). Besides, when the operation is set to “DISPLAY LIMIT”
mode, the meter will display setting value (now the symbol of “＊” is on
without blinking). When the output is set to OFF, the output current
setting can be done by pressing [I SET] directly or by changing the
“DISPLAY LIMIT” mode (please refer to the operation of DISPLAY
LIMIT).
Setting method 1: Press [I SET][Number key (current value)] [ENTER]
to set output current.
Setting method 2: Press [I SET][number knob (voltage value)] to change
the output current setting immediately, then press again [I SET] to
complete current setting.。When use this method with the output on, the
input current will be changed following the input value by rotating the
knob which can be adjusted by moving the [＜] or [＞] cursor.
For example: Set output voltage to 20.00A
Press [I SET][2][0][.][0][0][ENTER] or [I SET][2][0][ENTER]

When the current load runs through output terminal, if the current
exceeds the setting value, the operation of the instrument will be set to
Constant Current Mode (C. C. Mode), if the current does not exceed the
setting value, the operation will be set to Constant Voltage mode (C. V.
Mode).
z OVP SET: Over Voltage protection setting (LEVEL, ON/OFF
/CLEAR)
Setting method: After pressing [OVP SET], get into Over Voltage
Protection Level setting, now use the number key (or knob) to input
setting value, then press [ENTER] to complete the setting change.
When get into Over Voltage protection state setting by selecting Over
Voltage protection state and pressing [ENTER], use the knob to select
ON/OFF/CLEAR, then press [ENTER] to complete the setting change.
Remark: When the Over Voltage protection of the instrument is
triggered, use the function of Over Voltage Protection
Clear (OVP CLEAR) to clear its protection state.
For example: Set Over Voltage protection value to 21.00V at ON state.
After pressing [OVP SET] to get into OVP LEVEL setting, then input
[2][1][.][0][0][ENTER] to get into OVP STATE setting, now set the
knob select state to ON and press [ENTER] to complete setting.
