● IDENTIFYING LINE CONDITION (SWITCH TO "POLARITY")
1.●Connect●the●RED●test●lead●to●the●RING●SIDE●of●the●line●and●the●
● BLACK●to●the●TIP.●(See●Figure●3)
2.●Watch●the●LED:
1.1● ● A●BRIGHT●"GREEN"●LED●indicates●a●CLEAR●line.
1.2● ● A●DIM●"GREEN"●LED●indicates●a●BUSY●line.
1.3● ● A●BRIGHTLY●FLICKERING●"GREEN●and●RED"●LED●indicates●a●
RINGING●line.
● VERIFYING LINES (SWITCH TO "POLARITY" THEN "CONTINUITY") ●
1.●Dial●the●line●to●be●verified.
2.●While●the●line●is●ringing,●connect●the●RED●lead●to●the●RING●SIDE●of●● ●
● the●line●and●the●BLACK●to●the●TIP.
3.●In●the●"POLARITY"●position,●the●indicator●lamp●will●flicker●"RED●and●● ●
● GREEN"●when●the●test●leads●are●connected●to●the●subject●pair.
4.●If●you●switch●the●test●set●to●"CONTINUITY",●it●will●terminate●the●call●on●●
● the●subject●line.
● SENDING TONE (SWITCH TO "FAST TONE" or "SLOW TONE") ●●●●●●●●
CAUTION:DO NOT CONNECT TO ANY ACTIVE AC CIRCUIT
EXCEEDING 24V IN THIS MODE.
1.●Connect●the●test●leads●to●the●pair,●or●attach●one●lead●to●ground●and● ●
● one●lead●to●either●side●of●the●line.(See●Figure●1)
2.●A●fast●dual●alternating●tone,●or●a●slow●dual●alternating●tone●can●be●
● selected●from●the●function●rotaty●switch.
3.●Probe●the●suspected●wires●with●the●amplifier●probe.●Reception●of●tone●●
● will●be●strongest●on●the●subject●wire.●In●case●of●ready●access●to●bare●● ●
● conductors,●a●handset●or●headphone●may●be●used●to●receive●the●tone.
● TESTING CONTINUITY (SWITCH TO "CONTINUITY") ●●●●●●●
CAUTION:DO NOT CONNECT TO ANY ACTIVE AC OR DC CIRCUIT
IN THIS MODE.
1.●Connect●the●test●leads●to●the●subject●pair.
2.●Switch●to●"CONTINUITY".
3.●A●bright●"GREEN"●light●indicates●continuity.●The●LED●will●not●glow●if● ●
● the●line●resistance●exceeds●12kΩ●
