[Test-Equipment] Evaluation of two DMMS

I have two Fluke 8025A multimeters that read differently on the ohms scale.

Using the same test leads on each, the ohms scale reads differently on the two meters. With the leads shorted on the ohms scale of one of the Flukes the resistance reading is .2 ohms. The other meter, using the same test leads, when they are shorted, reads 10+ ohms.

I would like your input regading how useful the meter that has the higher ohms reading might be in service work. Measuring a 9 vdc battery on the DC scale reads within .01 vdc, so the difference is in the ohms scale.

I am not sure how the ohms reading differing will affect the utility of the higher reading meter in service work. 

Your comments will be appreciated. Thanks and 73, John, K5PGW
