The
µA
has a 400.0µA and 4000 µA range, with auto ranging; the
mA
has a
40.00mA and 400.0mA range, with auto ranging;
A
position has a 4.000A and
10.00A range, with auto ranging.
To measure current, do the following:
1. Turn off power to the circuit Discharge all high voltage capacitors.
2. Insert the red test lead into the
µA mA
or
10A
or terminal and the
black test lead into the
COM
terminal.
3. Set the rotary switch to
µA
,
mA
or
A
. Use the
10A
terminal and
A
measurement position if the current value to be tested is an unknown.
4. The Multimeter defaults to DC current measurement mode. To toggle
between DC and AC current measurement function, press
BLUE
button. AC current is displayed as an mean value (calibrated against
sine wave effective value).
5. Break the current path to be tested. Connect the red test lead to the
more positive side of the break and the black test lead to the more
negative side of the break.
6. Turn on power to the circuit.
The measured value shows on the display.
Note:
•
For safety sake, the measuring lime for high current should be < 10
seconds for each measurement and the interval time between 2
measurements should be greater than 15 minutes.
