Hello Rob,
Thank you for your writing in.
Would you please tell us more details about your requirement?
For example,the measuring range, power supply and etc.
Best regards.
Our range is -30 VDC to +30 VDC and 10A. Our power supply is 24 VDC. We purchased the meter that has a range of 0-100VDC 10A and because no being able to read negative voltage it did not work. Thanks
