英国TTi微欧姆表BS407
- High basic uracy of 0.1%
- Wide measurement range of 1μW to 20kW
- Current reversal switch for detecting thermal emf
- Current persion switch for easy zero setting
- Four terminal measurement using Kelvin clip leads
- Battery operation with built-in charger
- Switchable 20mV clamp for ‘dry circuit’ testing
The BS407 is fully optimised for the task of urate measurement of low resistances
with a best resolution of 1μW.
It uses a Direct Current technique to measure true resistance, rather than the resistive
component of impedance which is shown by AC excited LCR bridges. The test current
for each range has been chosen to minimise heating of the sample under test while
being sufficient to minimise the effects of thermal emf and noise.
This gives much greater uracy at low resistances than can be obtained from the
very low test currents used by general purpose high resolution multimeters.
