3. Disconnect the test leads from the circuits under test, turn
the thumbwheel to the “OFF” position, and remove the test
leads from the input terminals.
4. Open the battery cover, taking into account its opening
mechanism; Insert a coin into the notch on the cover and
press the coin to open the locking buckle. Finally slide the
cover down. Please do not use sharp tools to force open the
cap, or the caliper housing will be damaged.
5. Remove the batteries and replace them with 4 new 1.5V
batteries. New batteries should not be used with old
batteries.
6. Close the battery cover properly.
