Sonel WMUSMIC05S1 Insulation Resistance Meter

Features:

• User-selectable test voltage any from 50 to 1,000 V (with 10 V resolution) and 1,000 to 5,000 V (with 25 V resolution)
• Continuous indication of measured insulation resistance or leakage current
• Audio beeps every five-second periods to indicate measurement progress
• Indication of actual test voltage during measurement
• 1.2 mA, 3 mA and 5 mA test current
• Step voltage and ramp voltage insulation resistance measurements (SV) (RV)
• Selectable test times (T1, T2, T3 from 1 to 600 seconds) to measure one or two absorption coefficients
• Adjustable measuring time to 99' 59''
• Polarization index (PI) and dielectric absorption ratio (DAR) measurements
• Dielectric Discharge calculation (DD)
• High-noise immunity; digital filters function for measurements in high noise environment (10 s, 30 s, 60 s)
• Adjustable limits for measured resistance RISO.
• Measurement of capacitance during the measurement of RISO
• DC and AC voltage measurement in the range of 0 to 600 V
• Meter conforms to EN 61557

Safety First Features:

• CAT-IV 600V, CAT-III 1000V
• Automatic discharge of tested object after the insulation resistance measurement completes to remove high voltage charge remaining due to cable capacitance
• Protection against measuring live objects, measurement will not proceed
• Measurements with test leads up to 65 ft / 20 m length
