Resistance and Continuity Measurements
1..Insert.the.black.test.lead.into.the.negative.COM.terminal.and.the.red.
test.lead.into.the.positive.terminal.
2..Set.the.function.switch.to.the.

.button.to.select.resistance.
4..Touch.the.test.probe.tips.across.the.circuit.or.component.under.test...
It.is.best.to.disconnect.one.side.of.the.device.under.test.so.the.rest.of.
the.circuit.will.not.interfere.with.the.resistance.reading.
5..For.Resistance.tests,.read.the.resistance.on.the.LCD.display.
6. For Continuity tests, if the resistance is < 150Ω, a tone will sound.

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.rotary.function.switch.to.the.cap.position.
2..Insert.the.black.test.lead.banana.plug.into.the.negative.(COM).jack.
Insert.the.red.test.lead.banana.plug.into.the.positive.(V)..jack.
3..Touch.the.test.leads.to.the.capacitor.to.be.tested.
4..Read.the.capacitance.value.in.the.display.
