4. Read the measured frequency on LCD screen.
3.2. 7 Current measurement
&.
Do not attempt a measurement on the current in a circuit,
·
if when the voltage between the open-circuit voltage and
the ground is over 250V. If the fuse is blown at the
moment of measurement, you are likely to damage the
meter or get yourself hurt.
To avoid any damage to the meter or equipment to be
measured, do not attempt a current measurement unless
you have examined the meter's protective tube. In
attempting a measurement, you should use the correct
input sockets, function positions and measuring ranges.
When a test lead is inserted into the current input socket,
do not put the other end of the test lead in parallel
connection with any circuit.
The meter provides DC current measuring ranges as follows: 60µA,
600µA,6mA,60.00mA,600.0mA and 10.00A; and AC current
measuring ranges: 60µA,600µA,6mA,60.0mA,600.0mA and 10.00A.
Measurement of current:
1. Turn the rotary switch to the appropriate position , Press "SEL"
to switch DC/ AC current function.
2. Connect the test lead in black to COM input socket. Connect the
test lead in red to a mA input socket when the measured current
is less than 600mA; connect the test lead in red to a lOA input
socket when the measured current is 600mA,.., 10A.
3. Disconnection of the circuit to be measured Connect the test
lead in black to the end of disconnected circuit (the voltage is
lower) and connect the test lead in red to the end of the
disconnected circuit (voltage is higher).
4. Connect the power to the circuit and capture the displayed
reading. If the display unit only shows "OL ", it means the input is
over
the selected measuring range. At this moment, turn the
rotary switch to a higher measuring range.
