using with electrical appliance of 1,000 watts for about one minute, the last figure will
increase by one (the electricity cost is 1 cent). Accumulated electricity cost can be
cleared to zero by pressing “DOWN” button for 5~10 seconds, but the accumulated
electricity consumption and running time will be cleared to zero at the same time.
5. Monitor operation conditions of electrical appliance:
Operate as above to make the screen display "RT" and the unit shows "%", figures on the
screen show the real-time ratio of operation condition.(as shown below)
Principle: Red indicator light flickers if the real-time running power is over the set
standby power for a period of time (=1 hour x the ratio of operation condition,
accumulated time in 1 hour). For example:
1) set ratio to 100% and standby power to 70W:
When the real-time running power is over 70W during the past 1 hour, the ammeter
will give out alarm (the indicator flickers);
2) Set ratio to 50% and standby power to 70W:
When the real-time running power is over 70W for 30mins (50% x 1 hour) during the
past 1 hour, the ammeter will give out alarm (the indicator flickers).
This function is particularly applicable to the refrigeration, heating and other
equipment to monitor their operation conditions.
6. Check running time of electrical appliance: running time shows on the top right
corner. It is the running time record of both the appliance and the ammeter. It stops
recording while power down, and restart to record from zero when connect to the power
again. Running time can be cleared to zero by pressing “DOWN” button for 5~10 seconds,
but the accumulated electricity consumption and cost will be cleared to zero at the same
time.
Two formats for display:
①
hh: mm (hours: minutes),":" flickers once a second, figures on “mm” increase by one
every 60 seconds (as shown below).
