it just peels off.
like taking off divers wet suit, same.

GDT3190 has a 1.5 V battery test position and if it does not have one then use DC Volts (V with straight line above) in any position higher then 1.5 V (eg. 2V)

For best use for your model multimeter I would recommend downloading a manual on the initial setup for testing and what you should look for.

what about it?

check online at GB's site, some manuals are available as a pdf

so do I
I will call them and post the answer

The settings are the different voltage levels A.C. -D.C. and ohm values of resistor and amp values and there is a diode tester and a continuity tester

On my GDT 3200 you had to pry and force the black padded case off of it. There is no instructions how to put the batteries in, and I nearly broke the meter taking off the case. Just try to force that case off of there. Hand strength combined with frustration and anger will help in that step. Once the black armored case is off, it's self explanatory. There's two screws on the back that come out and the red unit splits in two. Install the batteries and put it back together.

Have you tried the GardnerBender.com website?

Set it to OHM or resistance and read the element
