Setting Limiters
1. Setting Types
Two types of limit value settings are available; one is
Balance setting. This sets the same absolute
value on both the polarities, + and -; the other is Separate setting. This sets a different value on each
polarity.
For more information on these settings, refer to Section 2.2.2, "Setting Limit Values."
2. Setting ranges
For the HI limit and the LO limit values, the ranges are always the same.
The setting values are set in the optimal ranges.
3. Usage for Separate setting
Setting both the HI limit and LO limit values to + (positive) voltage can be used for rechargeable bat-
tery charge and discharge testing.
Figure 5-13 Rechargeable Battery Charge and Discharge Operations
Setting the HI limit value as voltage for charging constant voltage and the LO limit value as voltage
for discharging termination provides CV/CC operation as shown in the above figure.
NOTE:
Applying higher voltage than the HI limit value or lower voltage than the LO limit value from an
external device sets overload (OVL) and then Standby.
For example, connecting a battery of lower voltage than the LO limit voltage results in overload
(OVL) and then Standby.
