Resistance Measurement; Continuity Check - Beta 1760 B Manual De Usuario E Información De Seguridad

RESISTANCE MEASUREMENTS
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.
1 Set the function switch to the Ω position.
2 Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana
plug into the positive Ω jack.
3 Touch the test probe tips across the circuit or part under test. It Is best to disconnect one side
of the part under test so the rest of the circuit will not interfere with the resistance reading.
4 Read the resistance in the display. The display will indicate the proper decimal point, value

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
2 Insert the black lead banana plug into the negative (-) jack (COM) and the red test lead banana
plug into the positive (+) jack (Ω).
3 Touch the test probe tips to the circuit or wire you wish to check.
4 If the resistance is less than approximately 50Ω, the audible signal will sound. The display
will also show the actual resistance.
