2. Feature
KEW3126 is a microcomputer controlled, high voltage insulation
resistance tester with 4-range for measuring insulation resistance.
● Designed to following safety standards:
IEC 61010-1 (CAT.III 600V Pollution degree 2)
IEC 61010-031 (Requirements for hand-held probes)
● With auto-discharge function
When insulation resistance like a capacitive load is measured,
electrical charges stored in capacitive circuits are automatically
discharged after measuring. Discharge can be checked on the
voltage monitor.
● Backlight function to facilitate working at dimly illuminated location
or at nighttime work.
● Bar graph to display measured result
● LIVE circuit warning symbols plus audible warning
● With Auto-power off function
To prevent the instrument being left powered on and conserve
battery power, the instrument automatically turns off approx.
10 min. after the last switch operation.
● Auto-measurement and display of DAR (Dielectric Absorption
Ratio) and PI (Polarization Index)
● Filter function to reduce the variations in readings due to external
influences
● With a short current of max 5mA, quick measurement is possible
even if the object under test has capacitive components.
