7.6 AC Current Measurement:
WARNING!
If the magnitude of the current to be measured is unknown, always
start by setting the meter to the highest range, and then to lower
ranges, until a satisfactory reading is obtained.
Do not rotate the RANGE switch with the input applied to the meter.
If the input current is higher than 20A, do not attempt to measure!
Use caution when measuring current in a circuit with voltages
above 30 VAC. Do not use meter to measure current in
circuits whose voltage exceeds 250V AC/DC.
7.6.1 Connect the black test lead to the COM jack. Connect the red
test lead to the 20A jack unless it is known that the input
current is less than 200mA. If the current is less than 200mA,
connect the red test lead to the uA mA jack.
7.6.2 If the red test lead is inserted into the 20A jack, set the RANGE
switch to the 20 A~ position. Connect the test leads IN SERIES
with the circuit to be measured. Read the value of the current on
the LCD display.
