Diode Test
WaRninG:
.To.avoid.electric.shock,.do.not.test.any.diode.that.has..
voltage.on.it.
1...Set.the.function.switch.to.the.
.position.
2..Insert.the.black.test.lead.plug.into.the.COM.socket.and.the.red.test.
lead.plug.into.the.
.socket.
3..Press.the.MODE.button.until.“
”.appears.in.the.display.
4..Touch.the.test.probe.tips.to.the.diode.or.semiconductor.junction.you.
wish.to.test..Note.the.meter.reading.
5..Reverse.the.probe.polarity.by.switching.probe.position..Note.this.reading.
6..The.diode.or.junction.can.be.evaluated.as.follows:
A..If.one.reading.shows.a.value.and.the.other.reading.shows.OL,.the.
diode.is.good.
B..If.both.readings.show.OL,.the.device.is.open.
C..If.both.readings.are.very.small.or.zero,.the.device.is.shorted.
noTE:
.The.value.indicated.in.the.display.during.the.diode.check.is.the.
forward.voltage.
Capacitance Measurement
WaRninG:
.To.avoid.electric.shock,.discharge.the.capacitor.under..
test.before.measuring.
1..Set.the.function.switch.to.the.
CaP
.capacitance.position.
2..Insert.the.black.test.lead.banana.plug.into.the.negative.
CoM
.jack.and.
the.red.test.lead.banana.plug.into.the.
CaP
.positive.jack.
3..Touch.the.test.probe.tips.across.the.part.under.test.
4..Read.the.capacitance.value.in.the.display.
5..The.display.will.indicate.the.proper.decimal.point.and.value.
noTE:
.For.very.large.values.of.capacitance.measurement.time.can.be.
several minutes before the final reading stabilizes. The bar graph
is.disabled.in.capacitance.measurement.mode..The.LCD.displays.
DiS. C
..Discharging.through.the.chip.is.quite.slow..We.recommend.
the.user.to.discharge.the.capacitor.with.some.other.apparatus.
