5 Device operation  
5.1 Setting output voltage  
Put VM/Vout switch [(10)] to Vout position  
Put C/V switch [(8)] to V position  
Volt LED indicator will light up [(4)]  
[(3)] will display “U” for Volt  
Adjust the voltage controller [(5)] to get the  
required value.  
The value will be displayed on [(2)] with one  
decimal place  
Note: Make sure to keep reasonable current limiting  
value before setting output voltage so that current  
control (CC) will not take over.  
5.2 Setting current limit  
Press and hold C-SET button [(7)].  
Then display[(2)] will show the present current  
limit in Amperes.  
[(3)] will display “A” for Current  
Now rotate the current controller knob [(6)]  
while looking at the display. Stop when the  
desired value appears.  
Note: The output voltage will be automatically be  
controlled if the external device tries to drag current  
more than the set limit.  
5.3 Viewing actual current flow  
Power up the DUT with PS1010-3A

Put VM/Vout switch [(10)] to Vout position  
Put C/V switch [(8)] to C position  
Amp LED indicator will light up [(4)]  
[(3)] will display “A” for Ampere  
Actual current value will be displayed on [(2)]  
with two decimal places  
5.4 Voltmeter mode  
5.4.1 Measuring voltage at various  
positions while powered from the  
PS1010-3A  
Set required output voltage and power up the  
DUT  
Put VM/Vout switch [(10)] to VM position. VM  
LED indicator [(4)] will light up.  
Test voltage values using the VM probe [(11)].  
The voltage values are displayed relative to the  
GND pin of the Vout terminal [(9)].  
Note: the user can select various switch positions at  
any time to see the Current limit, Actual current  
flow, voltage at output terminals or at VM without  
disrupting the power at the output terminals.

5.4.2 Measuring voltages at external  
sources  
Put VM/Vout switch [(10)] to VM position. VM  
LED indicator [(4)] will light up  
Connect wires as shown below(VM terminal and  
the GND of Vout terminals)  
Value will be displayed [(2)].  
5.5 Viewing firmware version  
Switch OFF the PS1010 [(1)]  
Put VM/Vout switch [(10)] to VM position  
Press and hold the C-SET button

Switch ON the PS1010-3A [(1)]  
[(3)] will show “F” to indicate Firmware version  
Display [(2)] will show the Firmware version in  
the following order.

Major version  
Build  
Minor version  
Note: PS1010-3A is not firmware upgradeable by  
the customer.  
6 Troubleshooting  
No display  
Check power cable/Input power  
Check power switch [(1)]  
Check fuse at the back of the PS1010  
Even if the voltage adjust knob is turned the value  
does not vary.  
Check whether the Volt LED indicator [(4)] is  
ON. If not then you are not in the right set up  
and follow up on how to setting the output  
voltage guide lines  
Check whether the CC LED indicator [(4)] is  
ON. If so then the current limiting occurs due to  
insufficient current limit adjustment or due to  
excessive current draw.

PS1010 is in its current mode and the Amp indicator  
is also ON. But rotating current controller knob does  
not affect the display value.  
You are at the current mode and at this mode the  
display shows only the actual current draw by  
the DUT. But rotating the current controller knob  
means changing the Max current limit. To see  
the max current limit, C-SET button should be  
pressed.  
Cannot increase voltage from a certain value.  
Check whether CC indicator appears. If so,  
increase the current limit.
