2. If LCD displays "1" , it means overrange, should set the range
knob to a higher range.
3. Max. input current is 200mA or 20A (subject to where red lead
insert), excessive current will blow the fuse. Be careful when
measuring. Continuously measuring large current may heat the
circuit, affect the accuracy, eve damage the meter.
4.5 ACV MEASUREMENT
1. Insert the black test lead to "COM" jack and the red one to
"mA" jack(max. 200mA), or insert the red one to "20A" jack
(max. 20A).
2. Set the range knob to a proper ACA range; connect the test
leads across to the circuit under tested.
NOTE:
1. If the measured current range is unsure beforehand, should set
the range knob to the highest range, then set to a proper range
according to the displayed value.
2. If LCD displays "1", it means overrange, should set the range
knob to a higher range.
3. Max. input current is 200mA or 20A (subject to where the red lead
insert to), excessive current will blow the fuse. Be careful when
measuring. Continuously measuring large current may heat the
circuit, affect the accuracy, even damage the meter.
4.6 RESISTANCE MEASUREMENT
1. Insert the black test lead to "COM" jack and the red one to
"V/Ω" jack.
2. Set the range knob to a proper resistance range, connect
the test leads across to the resistance under measured.
NOTE:
1. If the resistance value being measured exceeds the max value of
the range selected, LCD displays "1", thus, should set the range
