RESISTANCE MEASUREMENT
1. Turnoffpowertotheresistancetobemeasuredanddischargecapaci-
tors.Anyvoltagepresentduringaresistancemeasurementwillcause
inaccuratereadings.
2. ConnectredtestleadtoV-ΩInputandblacktestleadtoCOMInput.
3. SetFunction/RangeSwitchtothedesiredposition.
4. Connecttestleadstoresistanceorcircuittobemeasured.
5. ReadresistancevalueonDigitalDisplay.Opencircuitswillbedisplayedas
anoverloadcondition.
 Note:Forlowresistancevalues,measureresistanceoftestleadsrst
bycontactingprobetips,anddeductthisvaluefromactualmeasurement.
CAPACITANCE MEASUREMENTS
1. Dischargeallvoltagefromthecapacitorbeforemeasuringitsvalue
(acrossa100kΩresistor).
2. InsertthecapacitorintheCxslotsortouchcapacitorleadswithprobe
tips(redtestleadconnectedtoCxinputandblackleadtoCOMinput).
3. SettheFunction/Rangeswitchtothecapacitancerangethatgivesthe
mostaccuratereading.
4. Readthecapacitancevalueonthedisplay.If“OL”appearsinhighest
range,thecapacitoristoolargetobemeasured.
