Connect the test leads to a battery.
Open-terminal voltages for the instrument are as follows:
3 m
Ω and 30 mΩ ranges: 25 V peak
300 m
Ω range: 7 V peak
3
Ω to 3000 Ω: 4 V peak
These voltages derive from the load associated with charging the 1.2 uF
capacitor inside the instrument.
• The open-terminal voltage for the 3 m
Ω, 30 mΩ, and 300 mΩ ranges peaks at
4 V approximately 500 ms after the terminal is placed in the open state.
• When building a measurement line using scanners, use a relay with a dielec-
tric strength that is greater than or equal to the open-terminal voltage for the
range being used.
