5.3 Alarm Function
·Turn on/off Alarm Function
When the upper/lower limit is different but as “0”, it represents the alarm function is enabled.
When the upper/lower limit is “0”at the same time, it represents the alarm function is forbidden.
· Alarm Function
After the alarm function is enabled, the system waits to connect the load. When the system detects the
voltage and current are both greater than “0”, it will recognize the load is connected and start to count the
time. After the alarm delay, the system will compare the measured value with the upper/lower limit, if the
measured value is within the upper/lower limit, the interface displays “OK”; if the measured value is higher
than the upper limit, the interface displays “Hi”, and the beeper will alarm; if the measured value is lower
than the lower limit, the interface displays “Lo”, and the beeper will alarm. When the load is removed, the
system waits for load access again, the alarm sign is eliminated, and the beeper is turned off.
