Operation Overview

REPEAT: Set the number of time to repeat (0=infinite loop).
I_RANGE: Set the current measurement range of Electronic Load. There are H, M and L for
selection.
Ranges (Low, Middle, High)
Resistance can be programmed in any of the three ranges, low range, middle range and
high range. The low range provides better resolution at low resistance setting. If any value
is over the maximum of low range, you must select the middle range. When any value is
over the maximum of middle range, you must select the high range. To change the range,
press the
RANGE
key few times until the VFD range indicator is active at you want to select.
The mode change will affect the Load, so will the change of range. Both of them will cause
the input to go through an off state. If the CRD mode of Load is active, the new setting will
change the input immediately at a rate determined by the slew rate setting.
