4. operation
notice: read and understand all warning and precaution statements listed in the safety section of this operation manual prior to using this meter.
set the function select switch to the off position when the meter is not in use.
4.1.
AC CURRENT MEASUREMENTS (fig.4)
Warning! ensure that the test leads are disconnected from the meter before making current clamp measurements.
‰
4.1.1.
set the function switch to the 400.0A ~ 2.000A range.
4.1.2.
If the range of the measured is not known, select the higher range first then move to the lower range if necessary.
4.1.3.
Press the trigger to open jaw. fully enclose one conductor to be measured. the clamp meter lcd will display the reading.
4.2.
dc / ac voltage measurement
4.2.1.
insert the black test lead into the negative com terminal and the red test lead
into the positive V terminal.
4.2.2.
set the function switch to the V position.
4.2.3.
select Ac or dc with the mode button.
4.2.4.
connect the test leads in parallel to the circuit under test.
4.2.5.
read the voltage measurement on the lcd display.
4.3.
resistance measurement
4.3.1.
insert the black test lead into the negative com terminal and the red test lead
into the positive terminal.
4.3.2.
Set the function switch to the Ω
4.3.3.
touch the test probe tips across the circuit or component under test. it is best to disconnect one side of the device under test so the
rest of the circuit will not interfere with the resistance reading.
4.3.4.
for resistance tests, read the resistance on the lcd display.
4.4.
diode and continuitY measurements (fig.5)
4.4.1.
insert the black test lead banana plug into the negative com jack and the red test lead banana plug into the positive diode
jack.
4.4.2.
Turn the rotary switch to the Ω
4.4.3.
Press the mode button until "
4.4.4.
touch the test probes to the diode under test. forward voltage will indicate 0.4V to 0.7V. reverse voltage will indicate "ol".
shorted devices will indicate near 0mV and an open device will indicate "ol" in both polarities.
