252 U3606A User’s and Service Guide
Overload ranging: Will select higher range if peak input overload is detected during
auto range. Overload is reported in manual ranging.
AC current
Measurement method: AC coupled true rms
Maximum input current: 10 mA to 3.0 A DC or AC rms
[1]
Burden voltage and shunt
resistance:
• < 0.2 V, 10 Ω for 10 mA range
• < 0.2 V, 1 Ω for 100 mA range
• < 0.3 V, 0.1 Ω for 1 A range
• < 0.7 V, 0.01 Ω for 3 A range
Input protection Protected with a 3.15 A/500 V, FF fuse
Crest factor: For < 5:1 errors included. Limited by the peak input and 100 kHz
bandwidth. Maximum 3.0 at full scale.
Peak input: 300% of range. Limited by maximum input.
Response time: Approximately 2.5 s when the displayed reading reaches 99.9% AC
rms value of the tested input signal at the same range.
[1] Any current measurement greater than 500 mA will have a temporary thermo-effect. If you wish to
measure a smaller current or offset current measurement immediately after a high current
measurement, ensure that the U3606A is cooled down.
Resistance
Measurement method: Two-wire, open-circuit voltage limited to < 5 V
Open circuit voltage: < +5.0 V
dc
Input protection: 1000 V
rms
on all ranges, < 0.3 A short circuit
Response time: Approximately 0.15 seconds for 1 MΩ and ranges below 1 MΩ.
Low-resistance
Measurement method: Four-wire, the test current is sent from the FORCE terminals and the
resistance is measured by the SENSE terminals.
Input protection: • FORCE terminals: 1000 V
dc
on all ranges, protected with a 3.15
A/250 V FF fuse
• SENSE terminals: 1000 V
rms
on all ranges, < 0.3 A short circuit
