２．Features
MODEL3161A is a two-range insulation resistance tester for
testing various elevators and safety equipments.
¡
Designed to following safety standards:
IEC 61010-1, IEC 61010-031, IEC 61557 (500V/ 100MΩ only)
¡
Small and light weight.
¡
Auto-discharge function
When insulation resistance like a capacitive load is measured,
electric charges stored in capacitive circuits are automatically
discharged after measuring. Discharge can be checked with the
meter.
¡
Color-coded scales for easy and correct reading
¡
Power-on indicator on insulation resistance and battery check
ranges.
¡
Backlight function to facilitate working at dimly illuminated
location or at nighttime work.
¡
AC voltage measurement function
¡
Measures AC voltage on all ranges without pressing the Test
button
¡
Test leads with remote control switch
(voltage won't be outputted when the test lead is not connected.)
¡
Robust housing case
¡
Neck strap for both hand's operation
¡
