AC Clamp on current meter to measure dc current??

[rfranzk]

Hello Everyone.  I have a fairly inexpensive clamp on multimeter with ac current capabilities 20 amps to 400 amps.  I work more with dc and am curious if a modification could be made to read dc current with some accuracy.  I sometimes measure currents at 300 to 400 amps dc with voltages between 12 and 48 volts. (Automotive and electric golf carts)  I have a dc current probe that interfaces with my dmm that is limited to 30 amps for smaller measurements. 

Thanks in advance for any ideas and feed back.  rfranzk.

It's not possible.

Cheap AC clamp meters use a current transformer principle which only works on AC currents, for DC you need a hall effect sensor. A DC clamp meter will cost more but  that's life.

Thanks for your reply.  I guess I will either have to pony up and purchase one or put another project on the burner. I appreciate the input. I would be interested in schematics for a dc clamp on meter. 
Thanks. rfranzk
