4.2.6.2 Setting Limit Values
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 Individual setting. This sets a different value on each
polarity.
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 Individual setting
By setting both the HI limit and LO limit values to + (positive) voltage, the 6253 can be used for
rechargeable battery charge and discharge testing.
Figure 4-12 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.
CAUTION:
1. Applying higher voltage than the HI limit value or lower voltage than the LO limit value
from an external device will cause overload (OVL) and then set Standby.
For example, connecting a battery of lower voltage than the LO limit voltage results in
overload (OVL) and then Standby.
2. To prevent damage to the 6253, do not apply a voltage or frequency that exceeds the
specified range.
