measurements of DC/AC voltage, DC/AC current, resistance, frequency, cycle, capacitance and
temperature.

1) Limit setting method
Select [High] or [Low], switch digits by left/right direction buttons, and modify digits by up/down
direction buttons.
2) Unit of limit
The unit of limit is decided by current measuring function.
3) Over-range indicator
The font of primary measurement will change to red from black and beeper will beep if the reading is
exceeding the high/low limit.
4) Range of limit operation
The set high limit should always higher than the low limit.
The high/low limits are saved in volatile memory, and will be auto reset to default value after power
off.
