Insulation resistance measurement (two-lead)

Measurement range acc. to IEC 61557-2: 50k…15,0 TΩ (I _ISOnom = 1,2 mA or 3 mA)

Values of measured resistance depending on measurement voltage

Measurement of leakage current

• I _L max – maximum current at short circuit of leads, 
• resolution and units result from the measurement range of individual insulation resistance.

Step voltage insulation resistance measurement

• duration of each "step" adjustable from 30s to 5mins 
• measurement result for each voltage step is stored in memory

• Voltage on open terminals: 4...24 V 
• Output current at R < 2 Ω: Imin > 200 mA (ISC: 200...250 mA) 
• Compensation of test lead resistance 
• Current flowing in both directions, mean value of resistance is displayed

Capacity measurement

• Capacity measurement result is displayed after the R _ISO measurement

DC and AC voltage measurement

The acronym “m.v.” stands for a “measured reference value”.
