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 20A 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.
