I must connect a TA009 clamp meter to an instruments with a 1Kohm imput impedance.

May i have problems? If yes, what can i do?

Thank you for your post.

The current clamps specification states that the load resistance is 10 kOhm minumum, and therefore your instrument with 1 kOhm input impedence will not work correctly. Either it will give small difference at the best or not work at all in the worst case.

Best regards,
