How to integrate a voltage meter in a circuit?

What am I doing wrong that the 15v voltage meter that I'm installing on my power supply would peg out with 1.2v on the output?

I have a Jameco 20626 (JE215) Adjustable Dual Power Supply Kit that I've put together. I want to put two Jameco 2162863 15vdc power meters on the outputs when I finish enclosing the device. When I have connected one of these meters over either the negative or positive outputs, the meter pegs out on 1.2vdc.

I'm working under the understanding that I should be able to just install the meters in parallel with the load to observe the output voltage. I'm unsure where I'm going wrong because I have limited experience and no datasheet on the voltage meter.

Thanks for your help!

Here is a link to the Jameco 20626 instruction manual with the circuit schematic.

Use a known voltmeter to monitor the output of your power supply before

hooking up the 15v meter. Perhaps your power supply is not performing

properly...



Otherwise check that there was supposed to be a series dropping resistor

with the 15v meter, not that I could see anything about that on either

the Velleman or Jameco sites, so the meter should read properly. you

could always hook the meter to a 1.5V battery or 9V battery to see if it

is correct. It may be defective of course...

Thanks for the reply!

I found simpson panel meter data sheets on mouser.com. They suggested 1k per volt measured for those products, so.... I'll try a 15k ohm resistor tonight when I get home.

Thanks again!

No problemo! Send a note to Edmonds if the series resistor is needed.
They don't say anything about that on their listing for the 15V meters
that I could easily find.

I meant JAMECO, not Edmonds - was on another topic about lens

replacement and got the names mixed up!

I just got home and tested the theory out. I put a 15k resistor in series with the meter and it works great! Guess I'll write to Edmonds, I mean Jameco ;) about that detail.

Thanks for your help John!
