CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or
wires that have voltage on them.
1) Set the function switch to the Ω
position.
2 Insert the black lead banana plug into the negative COM jack.
3) Insert the red test lead banana plug into the positive VHz% jack.
4) Press the MODE button until the symbol appears in the display.
5) Touch the test probe tips to the circuit or wire you wish to check.
6) If the resistance is less than approximately 50Ω, the audible signal will
sound. If the circuit is open, the display will indicate OL.
DIODE TEST
1) Set the function switch to the Ω
position.
2) Insert the black test lead banana plug into the negative COM jack.
3) Insert the red test lead banana plug into the positive VHz% jack.
4) Press the MODE button until the
symbol appears in the display.
5) Touch the test probe tips to the diode you wish to test. Note the meter
reading.
6) The diode can be evaluated as follows:
A) A forward voltage will typically indicate 0.400 to 0.700V.
B) Reverse voltage will indicate “OL”.
C) If both readings show OL, the device is open.
D) If both readings are very small or 0, the device is shorted.
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.
1) Set the function switch to the CAP position.
2) Press the MODE button until “nF” appears in the display.
3) Insert the black test lead banana plug into the negative COM jack.
4) Insert the red test lead banana plug into the positive VHz% jack.
5) If the value displayed on the screen isn’t zero then press the REL
button.
6) Touch the test leads to the part to be tested.
7) Read the capacitance in the display. The display will indicate the
proper decimal point, value and symbol.
