Disabling Fluke 8600A Battery

[Ted Busky]

The last time I turned on my Fluke 8600A about 6 months ago, it took a
couple hours to charge the battery. Now it shows only one digit on the
display. I checked the batteries and found 2 are 1.2 volts and 2 are
around .6
volts. I assume the meter is trying to charge the batteries rather
than operate. Is there some way I can disable the battery charger and
run off line power or do I have to buy new batteries?

Thanks for any input,
Ted Busky

 

Not exactly sure about the 8600 but many of this type are dependent on the
batteries for filtering the line power. I have simply removed batteries and
replaced them with electrolytic caps with success - though you probably
would want to insert the apropriate current limiting resistor between the
supply and the load as the charging current will no longer be loading down
the supply.
