RESISTANCE MEASUREMENTS
1. Insert RED test lead into V
jack , and BLACK test lead
5
into COM jack
Function Selector Switch
Resistance setting.
2. Remove power from circuit.
3. Measure resistance by connecting test
leads to circuit. The tester will auto-
range to display the measurement in
the most appropriate range.
NOTE: When in a Resistance setting and
the test leads are open (not connected
across a resistor), or when a failed
resistor is under test, the LCD
indicate " ". This is normal.
DO NOT attempt to measure resistance on a live circuit.
CONTINUITY
1. Insert RED test lead into + V
jack , and BLACK test lead
5
into COM jack
Function Selector Switch
the Continuity
2. Remove power from circuit.
3. Test for continuity by connecting
conductor or circuit with test leads.
If resistance is measured less than
10Ω, an audible signal will sound and
display will show a resistance value
indicating continuity. If circuit is open,
display will show " ".
DO NOT attempt to measure
continuity on a live circuit.
BATTERY TEST
1. Insert RED test lead into + V
jack and BLACK test lead into

COM jack
Selector Switch
9V BATT setting.
2. Connect BLACK lead to negative,
and RED lead to positive terminal
of battery.
3. The voltage
measured
will display
on the LCD
. Batteries
