Note
• If you change the range while a capacitive or inductive load such as a capacitor or coil is
connected, an abnormal load may be detected due to the energy build-up in the load, and
the output may turn off.
• In voltage source mode’s 10 mV and 100 mV ranges, because the GS200 uses a voltage
divider, the output resistance is approximately 2
Ω
. Therefore, these ranges are not suitable
when the GS200 is connected to a load that allows current to flow (a low-impedance load).
Also, four-terminal connection does not function for these voltage ranges. You must use the
two-terminal connection instead. Connect a high-impedance load, a load that is sufficiently
larger than the output resistance.
• If the range is changed, a glitch will occur in the output for several
μ
s to several hundred
μ
s.
• When the range is changed, the fractional part of the source level that is outside of the
range determined by the new source range is discarded. However, if the source level is
outside of the range determined by the new source range, the source level is set to 0.
• The source range is fixed. The GS200 does not have an auto range feature.
