The only type I am familiar with is the Bird 4391M. This a a digital display wattmeter whereas the Bird 43 is an analog (mechanical meter) device. The digital wattmeter has many functions available such as FWD PWR, RFL PWR, MOD, that are selected by front panel push buttons. It is a very versatile unit for measuring RF signal power. The one disadvantage to the digital wattmeter is that it needs to be powered to operate, either on AC line or the rechargeable battery pack. The Bird 43 wattmeter is a very simple unit to operate and requires no external power. You simply plug in the correct element, making sure the arrow on the element points in the same direction as the RF signal flow, apply the RF power and get the meter reading. With both types of wattmeters, the frequency and power range desired to be measured is determined by plug-in elements that go into the front panel of the unit. If using a Bird wattmeter, I would suggest using Bird elements. The ones made by Coaxial Dynamics are good, but the can sometimes cause calibration errors. I have calibrated the Bird wattmeters for many years and they are very durable. You may want to do an internet search on Bird wattmeters for more information on their particular functions. Hope this helps.

Can you tell if a wattmeter is not working right?
Yes, you can determine if a wattmeter is not working correctly by checking for discrepancies in the readings compared to expected values. If the wattmeter consistently shows values that are significantly higher or lower than those predicted by calculations or measurements from other reliable devices, it may be malfunctioning. Additionally, inspecting the connections, calibration, and condition of the wattmeter can help identify any potential issues. Regular maintenance and testing against a known standard can also aid in ensuring its accuracy.

How would you measure power using three watt meter and one watt meter for balanced and unbalanced loads?
The 'one wattmeter method' can only be used for balanced, wye-connected, loads where the load's neutral point is accessible. The wattmeter's current coil is inserted into any line conductor, and the voltage coil is connected between the same line and the neutral point. The wattmeter reading indicates the power of one phase, so the total power is three times the wattmeter reading.To measure the total power of a balanced or unbalanced wye- or delta-connected load, it is only necessary to use twowattmeters -this is called the 'two wattmeter method'. In this case, the current coils of each wattmeter are inserted into any two line conductors, and the voltage coils are connected between the two line conductors and the third line conductor. The sum of the two wattmeter readings will indicate the total power of the load.
What are advantages of electronic wattmeter?
The advantages of wattmeter include adequate for low frequencies, easy to operate and better technology. There are different types of wattmeter and each has specific advantages.

When was the wattmeter invented?
The wattmeter was invented in the late 19th century by Oliver B. Shallenberger in 1888.

Why the current coil of wattmeter has more thikness wire than pressure coil?
Current coil carries the current.
Is there any difference in values between the two wattmeter method and three wattmeter method if you apply these two methods in same load?
Blondel's Theorem states that you can have one less wattmeter than there are conductors supplying a balanced or unbalanced load. In either case, the sum of the wattmeter readings will give you the total power of the load.
