note!
Accuracy specifications consist of two elements:
(% reading) – this is the accuracy of the measurement circuit.
(+ digits) – this is the accuracy of the analog to digital converter.
note!

4. operation
Warning!
risk of electrocution. High-voltage circuits, both Ac and dc, are very dangerous and should be measured with great care.
AlWAYs turn the function switch to the “off” position when the meter is not in use.
if “ol” appears in the display during a measurement, the value exceeds the range you have selected. change to a higher range.
note! on some low Ac and dc voltage ranges, with the test leads not connected to a device, the display may show a random reaing.
this is normal and is caused by the high-input sensitivity. the reading will stabilise and give a proper measurement when connected to a
circuit.
4.1.
dc VoltAGe meAsurements
cAution: do not measure dc voltages if a motor on the circuit is being switched on or off. large voltage surges may occur that can
damage the meter.
4.1.1.
set the function switch to the highest V dc position.
4.1.2.
insert the black test lead banana plug into the negative (com) jack. insert the red test lead banana plug into the positive (V) jack.
4.1.3.
touch the black test probe tip to the negative side of the circuit. touch the red test probe tip to the positive side of the circuit.
4.1.4.
read the voltage in the display. reset the function switch to successively lower V dc positions to obtain a higher resolution reading.
the display will indicate the proper decimal point and value. if the polarity is reversed, the display will show (-) minus before the value.
