250V or 500V - Small & Compact Insulation Resistance Meter

Insulation resistance measurement: selectable measurement voltage: 250V or 500V continuous indication of measured resistance, very long operation time with one set of batteries: 14 h for measurement at UISO = 250 V, 11 h for UISO = 500 V, automatic discharge of tested object’s capacitance after measurement of insulation resistance, acoustic determination of 5 seconds time intervals that facilitates to take time characteristics during insulation resistance measurement, measurement current up to 1.4 mA, protection against measurement of live objects. Low voltage resistance measurement in range of 0…1999 Ω: measurement with current of <10 mA with resolution of 0,1 Ω, quick acoustic signalling for circuit resistance below 10 Ω. AC/DC voltage measurement in range of 0…600 V: automatic detection of voltage type (AC/DC). Autoranging. Suitable for 50 Hz and 60 Hz network. Backlit LCD display. AUTO-OFF function. Built-in flashlight. Meter meets the requirements of the standard IEC 61557-1 and IEC 61557-2.
