Forum for discussing PicoScope version 6 (non-automotive version)


Postby Andrea78 » Thu Jul 04, 2013 9:22 am

Recently I notice that the current measured by my Picoscope is slight different (alway lower) from a multimeter located in serial .
Can you suggest how to solve this problem? Thanks.

There could be several reasons for this.
Can you tell me how you are measuring this current, please?
Are you using a series resistor and measuring the voltage across it?
What is the value of this resistor and the level of current?
Is it a simple DC current or a mixture of AC & DC?
Are you using a x10 probe to connect across the series load resistor or using a direct x1 connection?
Is the series resistor in the supply lead or in the return lead of the circuit?
