ScrollthroughtheresultsonthemaindisplaywiththeR-DAR-PI-DDbutton,oron
thesmalldisplaywiththeV/TIMEbutton.
Use R(t) when carrying out a ‘time-controlled test’ to scroll through the interval
measurement values saved at the sampling rate specied in SET-UP. These
valuesareavailableuntilanothermeasurementistakenortheselectorswitchis
turned.
When measuring high levels of insulation(>1GΩ), it isadvisedthatthe “G”
guardterminalbeusedtoeliminatetheinuenceofsurfaceleakagecurrents.The
guardisconnectedbetweenthetwomeasurementcontactpoints,andthesurface
susceptibletosurfacecurrents,(e.g.dusty,dampcableortransformerinsulation).
Inthiscase,alligatorclipsarepreferabletotest-probesheldinthehand.
As soon as insulation measurement is stopped, the test circuit is automatically
dischargedusingtheinstrument’sinternalresistance.
