Hi
I have a general question regarding the PS HP6114A.
Right now, I currently don't have one. I only have the HP 6205C.
I am guessing that it would be okay to do this simple test instructions.

1. turn on ps; set power supply to +1.0 Vdc.
2. turn off ps; connect ps and dmm to figure below.

3. SET POWER SUPPLY TO INDICATE AMPS.
4. set power supply on.
5. increase power supply voltage until p/s current meter reads 1.0 AMPS.
6. Record DMM voltage reading
7. decrease power supply voltage to minimum output . set ps off.


I am confused with step#3 and #5.
how do I set power supply to indicate AMPS?

This is my power supply

"5. increase power supply voltage until p/s current meter reads 1.0 AMPS."... Do I continue to turn the V1 knob so that it goes pass .75 amperes?

Some information on what you are trying to do would help. Are you going through some test proceedure to check that the power supply meets it's specifications or are you testing some other piece of equipment ?

I am trying to this power transistor modules.
that's all the procedure was given.

I looked up the manual for the HP 6205C and it only goes up to 0.60 AMP.

I found the PS in the lab HP6114A, but I followed the instructions and I cant control the PS to move passed 0 AMPERES.

Note on the equipment says "CURRENT NOT CALIBRATED", and KEEP "CURRENT CONTROL" AT THE BLACK MARK.

Can metrology set the ps to only operate at certain limits?
can the power supply work for voltage meter but not current meter?

For the power supply you have, it has two ratings. One for 20 V and one for 40V. The last button selects the capabillity of the supply. e.g. 0-20 V, 0.6A max. Note, that isn;t enough for what you need to do.

The first button selects what the meter reads. Either volts or Amps.

The middle button, which is a x1 and x.1 tells you how to read the meter. 0 to 40 or 0 to 0.4 V and the same sort of thing for current/

==

You need a load to indicate amps. Does it work in voltage? At some voltage, the OVP will trip (screwdriver adjust on the front). It also looks like the OVP LED is missing which could indicate other problems. It needs to work in voltage first. Then you need to determine the voltage limit that the OVP is set at.

That particular supply has some straps on the back. At a minimum V+ and V+(sense) and V- and V-(sense) should be strapped together. That's what I remember from memory.

Power super supplies are not created equal.
There is CV;CC; CV/CC, CV/CL and 2 and 4 quadrant supplies.
C=constant, V=Voltage; L=Limit
2 quadrant means it will either sink or source current depending on polarity.
A 4 quadrant supply can source voltage and sink current at the same time. e.g.. Voltage is positive and current is negative.
