Sonel WMUSMIC10S1 Insulation Resistance Meter

Features:

• Insulation resistance to 40.0 TΩ
• User-selectable test voltage any from 50 V to 1,000 V (with 10 V resolution) and 1,000 V to 10,000 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)
• Digital filters function for measurements in high-noise environment (10 s, 30 s, 60 s)
• High-noise immunity, up to 1550 V (induced)
• Adjustable limit settings for measured resistance RISO
• Measurement of capacitance during the measurement of RISO
• DC and AC voltage measurement in the range of 0 V to 600 V
• Graphical display of R and V, or R and I, plots the progress of test in real-time, and final graph
• Meter conforms to EN 61557

Safety First:

• CAT-IV 600V, CAT-III 1000V
• Automatic discharge of tested object after measurement completes to remove high voltage charges remaining on cable
• Protection against measuring live objects, measurement will not proceed
• Measurements with test leads up to 180 ft / 55 m length
