For example, if the cut-off enable is set to 3, there are 3 cut-off voltage values that can be

configured.

If the instrument operates at this time, it will check if the measured voltage is less than

cut-off voltage 1;

If so, it will determine if the measured voltage is less than cut-off voltage 2;
If so, it will determine if the measured voltage is less than cut-off voltage 3;
If so, the channel will be automatically deactivated and the battery measurement will be

completed.

In general, cut-off voltage 1 > cut-off voltage 2 > cut-off voltage 3. If set as shown in Figure

7-2-5, the measured voltage will be less than 8V, and will be definitely less than 12V and 10V,
making the conditions for the latter two cut-off voltages ineffective.

Fig. 7-2-5 Cut-off Voltage

Under other conditions, the cut-off enable can only be set to 1, and if the measured voltage is

less than cut-off voltage 1, the channel will be automatically deactivated and the battery
measurement will be completed.

Cut-off Time:

Set the cut-off value when time is selected as the cut-off condition. After the

channel operates based on the cut-off time value, it will be automatically deactivated and the
battery measurement will be completed.

Cut-off Capacity:

Set the cut-off value when capacity is selected as the cut-off condition. After

the capacity value accumulates to the cut-off level, the channel will be automatically deactivated
and the battery measurement will be completed.

Cut-off Energy:

Set the cut-off value when energy is selected as the cut-off condition. After the

energy value accumulates to the cut-off level, the channel will be automatically deactivated and
the battery measurement will be completed.
