1 - Setting the Output Voltage, Current, and Compensation
This example shows you how to set the output voltage and current. It also shows you how to set the
compensation circuit for either high or low capacitance cellular phones. Note that no front panel changes
affect the output of the unit unless it has been enabled.
Set the output voltage
Action
1.
To enter an approximate value without using the voltage menu: On the Entry keypad,
press
or
to select the 1's digit in the voltage field. Then rotate the front panel
RPG knob to obtain 7 V.
If the unit is in CC mode, you won't see the output voltage change until the voltage
setting is low enough to cause the unit to go into CV mode.
2.
The easiest way to enter an accurate value: On the Function keypad, press Voltage.
On the Entry keypad, press Enter Number, 7, Enter.
3.
To make minor changes to an existing value: On the Function keypad, press
Voltage. On the Entry keypad, press
that you wish to change. For example, move the flashing digit to the ones column to
change a value in this column. Then, press
press Enter.
Set the output current limit
Action
1.
To enter an approximate value without using the current menu: On the Entry keypad,
press
or
to select the tenths digit in the current field. Rotate the front panel
RPG knob to obtain 0.4A.
If the unit is in CV mode, you will not see the output current change until the current
setting is low enough to cause the unit to go into CC mode.
2.
The easiest way to enter an accurate value: On the Function keypad, press Current.
On the Entry keypad, press Enter Number, .4, Enter.
3.
To make minor changes to an existing value: On the Function keypad, press
Current. On the Entry keypad, press
that you wish to change. For example, move the flashing digit to the tenths column to
change a value in this column. Then, press
press Enter.
NOTE:
To output currents pulses greater than 3 A and up to 5 A peak, you must set the output
current limit to greater than 3 amperes (3.0712 amperes max).
