1.
Connect the red test lead to "V. Ω. mA" jack and black test lead to the "COM" jack.
(The polarity of red lead is positive "+".)
2.
Set the rotary switch at desired "Ω" range position.
3.
Connect test leads across the resistor to be measured and read LCD display.
4.
If the resistance being measured is connected to a circuit, turn off power and discharge all

If " "appears on display, it indicates that the battery should be replaced.
Fuse rarely need replacement and blow almost always as a result of operator's error.
To replace battery and fuse (FH 500mA/500V 10A/500V) remove the 2 screws in the bottom of the
case. Simply remove the old, and replace with a new one. Be careful to observe battery polarity.
