Specification
Sigma Delta A-to-D converter
10 MΩ ± 2% range (typical)
1000 VDC or PEAK AC on all ranges
1000 V on all ranges
Approximately 1.0 second when the displayed reading reaches 99.9% DC value of the tested input
signal at the same range
U3401A
–– 0.01 Ω to 100 Ω for 500 µA to 10 A ranges
U3402A
–– 0.1 Ω to 10 Ω for 12 mA to 1.2 A ranges
–– 0.01 Ω for 12 A range
mA input terminal: 1200 mADC or AC RMS. Protected with 1.25 A/500 V, IEC-127 sheet, FB fuse
12 A input terminal: 10 ADC or AC RMS continuous; or 12 ADC or AC RMS for 30 seconds maximum.
Protected with 15 A/600 V, breaking capacity 10,000 A FB fuse
Approximately 1.0 second when the displayed reading reaches 99.9% DC value of the tested input
signal at the same range
AC-coupled true RMS: measures the AC component with up to 400 VDC bias on any range
Maximum 3:0 at full scale
U3401A: 1 MΩ in parallel with <100 pF
U3402A: 1 MΩ ± 2% in parallel with <120 pF
U3401A: 1000 V RMS/1400 V PEAK
U3402A: 750 V RMS/1200 V PEAK
2x10⁷ V-Hz product on any range, normal mode input
1x10⁶ V-Hz product on any range, common mode input
Selects higher range if peak input overload is detected during auto range. Overload is reported in
manual ranging.
U3401A: 1000 V RMS on all ranges
U3402A: 750 V RMS on all ranges
Approximately 1.5 seconds when the displayed reading reaches 99.9% AC RMS value of the tested
input signal at the same range.
