RESISTANCE MEASUREMENT
1. Connect the red test lead to "Ω
to the "COM" jack (The polarity of red lead is positive "+").
2. Set the rotary switch at desired "Ω" range position.
3. Connect test leads across the resistor to be measured and
read LCD display.
4. If the resistance being measured is connected to a circuit
turn off power and discharge all capacitors before applying
test probes.
NOTE:
1. If the resistance being measured exceeds the maximum
value of the range selected or the input is not connected, an
overrange indication
2. When checking in-circuit resistance, be sure the circuit under
test has all power removed and that all capacitors have been
discharged fully.
AUDIBLE CONTINUITY TEST
1. Connect red test lead to "Ω
"COM" jack.
2. Set range switch to " " position.
3. Connect test leads to two points of circuit to be tested. If
continuity exists, built-in buzzer will sound.
DIODE TEST
1. Connect the red test lead to "Ω
lead to the "COM" jack (The polarity of red lead is positive
"+".).
