4.5.Resistance Measurements

To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements.
Remove the batteries and unplug the line cords.
• Set the function switch to the position.
CAP
• Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive Ω Jack.
• Read the resistance in the display.

4.6.Continuity Check

WARNING: To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any resistance
measurements. Remove the batteries and unplug the line cords.
• Set the function switch to the CAP position.
• Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive jack.
• Press the MODE key to switch the continuity functions.
• If the resistance is less than approximately 50Ω, the audible signal
will sound.
If the circuit is open, the display will indicate "OL".

4.7.Diode Test

• Set the function switch to the
• Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive V jack.
• Press the MODE key to switch the Diode functions.
• For ward voltage will typically indicate 0.400 to 3.000V. Reverse
voltage will indicate "OL". Shorted devices will indicate near 0V and
an open device will indicate "OL" in both polarities.

4.8.Capacitance Measurements

WARNING: To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any capacitance
measurements. Remove the batteries and unplug the line cords.
• Set the rotary function switch to the
• Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V jack.
• Press the MODE key to switch the Capacitance functions.
• Read the capacitance value in the Display
