2. Set the range switch to desired AC or DC position.
If the
current magnitude to be measured is not known beforehand,
set the ranges switch to the highest range position and then
reduce it range by range until satisfactory resolution is
obtained.
3. Open the circuit to be measured, and connect test leads in
SERIES with the load in with current is to measure.
4. Current reading will be displayed on LCD, for DC current
measurement, the polarity of the red probe will also be
indicated.
Please note:
When the display shows the over range symbol “1”, a higher
range must be selected. In addition “10A” function is designed
for intermittent use only.
RESISTANCE MEASUREMENT
1. Connect red lead to “VΩ”, black lead to “COM”.
2. Set the range switch to desired Ω range.
3. If the resistance being measured is connected to a circuit, turn
off power and discharge all capacitors before measurement.
4. Connect test leads to circuit being measured.
5. Read resistance value on Digital Display.
Please note:
 For resistance measurements >1MΩ, the meter may take
a few seconds to stabilize reading. This is normal for
high-resistance measurement.
 When the input is not connected, i.e. at open circuit, the
symbol “1” will be displayed as an over range indicator.
