6. START/STOPbutton
7. 6buttons(5050)or8buttons(5060),eachwitharstandsecondfunction.
Thesecondfunctionsarehighlightedinyellowbeloweachbutton:
• 2
nd
(yellow button)-Selectsthesecondfunctiononeachbutton.
• R-DAR-PI-DD - Lets you choose the type of measurement to be per-
formed. Instantaneous Resistance (R), Dielectric Absorption (DAR),
PolarizationIndex(PI),orDielectricDischarge(DD).
• R(t)-Shows/hidestheintervalvaluesofinsulationresistance,testvolt-
ageandtime-stamping,followingatime-controlledtest.
• V/TIME- Whenmeasuringinsulation,pressingthisbuttondisplaysthe
time elapsed since the beginning of the measurement, then the exact
voltagegenerated.Whenperformingresistanceorcapacitancemeasure-
ment,thisbuttonhasnoe󰀨ect.InMR(memoryrecall),itdisplaysthedate
andtimeatwhichthemeasurementwasstored,theexacttestvoltage
andtheOBJ:TESTnumber.
• -Activatesordeactivatesthe“time-controlled”testmode.
• -TurnsthedisplaybacklightONorOFF.
• ALARM- ActivatesordeactivatesthealarmsprogrammedinSET-UP.
• -Selectsaparametertobemodied.
• SMOOTH-Stops/startssmoothingofdisplayedvaluesduringinsulation
testing.
