AUTO POWER OFF
When the tester is idle for thirty minutes, with no function selector or button operation, it will turn itself off
automatically. To turn the tester on again, the user has to turn the function selector to “OFF” position, then the
selected function.
BATTERY CHANGING
When appears on the LCD, the battery need to be replaced with new ones. To replace the battery the
user should turn the function selector to OFF position. Then the user needs to open the battery compartment
cover with a screwdriver. Eight AA 1.5V batteries are needed to replace the old ones. After all Batteries are
changed, put the cover back and fasten the screw.
FUSE CHANGING
When connect the meter under Ohm rang to a source > 10V, the protection fuse will break the circuit and new
one will be needed for replacement. To replace the fuse, user should prepare an F 0.5A 600V fuse. First, the user
should turn the tester off and remove the test leads then remove the Back Cover and Replace the fuse.
