Fluke 1663 MFT Advice

Former Community Member

Hello

My fluke, intermittently gives a meassage ' batter lo 'indication when running low resistance continuity test (and doesn't then run the test) with a long lead and  when not zeroed ie continuity reading over a couple of ohms. The test current can toggle between 250mA or I think it's 20mA. It's fine at the lower current. The batteries are not flat. It's not the long lead as it's been tried with a new one and it does the same, Other leads have been changed, swapped etc and I'm sure it's the meter itself. Can't get any sense out of fluke technical.  It's done it from new. 2 years old and calibrated every year.  Anyone know why it might do this?  What are the quality of test result implications if I have  to use the lower current setting for doing the higher resistance readings

Driving me nuts and any help gratefully received

Thanks

    Do you have rechargeable batteries? This is a common effect with both NiCd and Lithium cells, the internal resistance increases with age, as well as charge retention. I have several (very expensive) batteries for my TV cameras. They are great until suddenly they won't keep the full charge and won't work the camera accessories such as the on-camera light.  Investigation shows the above, low capacity and higher internal resistance. New cells (these batteries have a lot of electronics inside) and all is well. Cold weather exacerbates these effects, just like the car battery too.
