SETUP INSTRUCTIONS
INSTALL BATTERY
The battery of your GT310 may or may not already be installed. If the
display remains dark after you turn the rotary dial to any position other
than OFF:
• Return the rotary dial to the OFF position.
• Disconnect test leads.
• Flip the meter over and lift the bottom of the yellow foldaway stand
on the back with your fingertip or a flat-blade screwdriver.
• Loosen and remove the two Phillips-head screws securing the
rectangular yellow plastic battery compartment cover. Set the cover
aside.
• Install a fresh “9V” battery in the compartment, with the (+) terminal
(anode) on the right (with the back of the meter facing you).
• Replace the battery compartment cover and resecure it with the
two screws.
INSERT TEST LEADS
Plug the red (fused) test lead into the right (red) socket on the front of
the meter and plug the black lead into the black socket. Remove the
clear plastic caps from the tips of the leads.
