Lets put some real values in there and assume that you are working with a laser that has a fixed 200 W output and a repetition rate that can be tuned from 20 Hz to 1 kHz. Typically people place it with double-sided adhesive tape. Again, lets use some real values and assume you are working with a CW laser that outputs 500 W. If you fire this laser at an object for exactly 5 seconds, then you have 500 W * 5 s = 2500 J. For example in that picture 1000 blinks of the led are equal to 1 kWh. If meter data is irregular, missing data will be recorded as null values with the standard 'log to feed' input process. INPUTS: Capacitance = 20F, Vpeak = 5 volts CW or pulsed laser: Pulse Energy (Joules) = Average Power (Watts) * Pulse Duration (Seconds). When this option is enabled, each new value received will be added as-is to the utility meter instead of adding the difference between the new value and previous value. The pulse output could be optical a blinking diode (flashing led) used for calibrating the unit or electrical (so-called S0) pulse output. Option 1: Wh/kWh readings that do not reset on power cycle e.g energy meters. $38.27. Free shipping. Unique design makes the meter entirely low-voltage, as the high voltage components are embedded in the Current/Voltage Transducer (CVT). Another example: if your 500 W laser has a 200 ms pre-programmed pulse duration, that will give you 500 W * 0.2 s = 100 J of total energy. Dont worry, in both cases, the equations are really simple: For a pulsed laser, you will need to divide the average power of your source by its repetition rate. Any energy meter has a pulse output option. Unique design makes the meter entirely low-voltage, as the high voltage components are embedded in the Current/Voltage Transducer (CVT). For the first type of pulses, you can just directly connect the pulse output to the pulse input ports of the data loggers. A motor watt-hour meter for dc energy measure as shown in Figure 1.5 essentially consists of a small motor that is provided with a magnetic breaking mechanism. Typically, they are galvanically separated pulses produced by an option in the energy meter. Slowness or fastness of Energy Meters Now, its time to calculate whether this Energy Meter is slow or fast.
