7.6.3
If the red test lead is inserted into the uA mA jack,
set the RANGE switch to the 200m A~ position.
Connect the test leads IN SERIES with the circuit
to be measured.
Read the value of the current on
the LCD.
7.6.4
If the display indicates overrange, i.e.
“1
- - -
”,
disconnect
the test probes from the circuit and reconnect the red
test lead to the 10A jack. Set the RANGE switch to the
20 A ~ position, and reconnect the test leads to the
circuit. Read the value from the LCD. If the display
indicates overrange, i.e.
“1
- - -
”,
the input current
exceeds the measurement capability of the meter, and
should not be measured.
7.6.5
If the displayed value is less than
“200”
(decimal point
not shown), a more accurate reading may be obtained
by setting the RANGE switch to a lower range.
Disconnect the probes from the circuit and rotate the
RANGE switch to the next lower position. Reconnect
the test probes to the circuit and observe the reading
on the LCD display. If the RANGE switch is already on
the lowest position (i.e. 2m), no greater measurement
resolution can be obtained.
