batteries should be used.
5-3. Mount the battery case back and tighten the screw.
Precaution:
1. Don’t input voltage higher than DC 1000V or AC Peak Value.
2. Don’t measure voltage at current, resistance, diode and
buzzer range.
3. Don’t use the instrument when the battery has not been
mounted properly or the back cover ahs not been tightened.
