Same as the current source range
However, if the current source range is 0.5 A, 1 A, or 2 A, the settings below apply.

Auto Range
When auto range is turned ON, the GS610 makes a measurement and checks whether a
different range setting is available for making the measurement with the best resolution.
If there is, the GS610 changes the range setting and makes the measurement again.
However, it may take time for the GS610 to switch the range setting, and the source
level may become discontinuous.
Measurement Delay
(See section 7.4 for the procedure)
The measurement delay is the wait time at which the measurement is started after the
source level is switched. It is used for the item being measured to stabilize.
The measurement delay can be set in the range of 1
µ
s to 3600 s. However, setting a
long measurement delay results in a long source measure cycle. Set the smallest value
possible.
Integration Time
(See section 7.5 for the procedure)
The integration time is the time that the integrating A/D converter performs integration. If
you increase the integration time, the time needed to make measurements takes longer,
but the measured values are more stable.
When the power frequency is 50 Hz: 250
µ

When the power frequency is 60 Hz: 250
µ
s, 1 ms, 4 ms, 16.6 ms, 100 ms, or 200 ms
If the integration time is set to 200 ms, 100 ms, 20 ms, or 16.6 ms, the effects of noise
from the power frequency can be eliminated, because these settings are integer
multiples of the power cycle.
Auto Zero Function
(See section 7.6 for the procedure)
When auto zero is ON, the GS610 also measures the internal zero reference for each
measurement. The measured result is obtained by subtracting this value from the
measured value canceling the offset drift of the measurement circuit in the GS610.
However, the measurement takes approximately twice as long, because the GS610
measures twice.
