××× D (day): unit shows “D” beside the figures(as shown below).
When the running time is less than 24 hours, figures will show in format ①
; when
running time surpasses 24 hours, figures will show in both format ①
and ②
alternately.
Application Example
1、 Measure if the power supply has electricity and if the socket is in good
condition:
Insert the ammeter into the socket of power supply, if the power supply has electricity
and the socket is in good condition, the LED indicator will flicker and LCD backlight will be
lightened. It can replace the neon-electroscope, especially when you find there is
electricity in the socket by the neon-electroscope, but it is abnormal when connecting
with the electrical equipments. At this very moment, it is easy and effective to use this
ammeter to tell whether the power supply or socket is in good condition.
2、Observe the real-time voltage fluctuations of power supply:
Choose the Voltage Measurement function, you can real-time observe and measure
the voltage fluctuation of power supply. It can be functioned to replace voltmeter.
3.、Measure whether the energy-saving lamp saves energy or not, and how
much energy it save in the end:
Choose the Power Measurement function, you can observe the luminance of the
energy-saving lamp, and measure the lamp’s real power consumption. Then, comparing
to other lamps with the same power, you can clearly know the energy-economizing effect
of the energy-saving lamp.
4、Measure the power consumption on electrical equipments:
This product has functions of Power Measurement, kilowatt-hour measurement, etc;
you can choose any of both to measure power consumption on electrical equipments.
Specially, it has 4 decimals to display kilowatt-hour, you can clearly and intuitively see
power consumption on electrical equipments at per second, per minute, per hour. Further
more, you can also easily measure detailed power consumption of these electrical
equipments in a period of time, through resetting time and power measurement to zero.
