4410 (OLDER VERSION) 4410A (LATEST VERSION)
4412 (120vac POWERED VERSION)
The meters mentioned all work the same way. By using internal
electronics to scale the element reading to the dial setting.
So.....like most other Bird meters the element determines how the meter
reads.
Or to put it another way you must use the correct element to get
accurate readings for the frequency and power you are measuring.
The element MUST be a 4410 series (4410-#) element or you can ruin the
meter.
Many 4410's I buy must be sent for repair / recalibration cause by improper
element use.
4410 elements and their common usage are at the bottom of this page.
The meters have a rotary multiplier switch on the front.
The first position is battery check. You need one 9 volt battery that it will
check to make sure you get accurate readings.
The Battery is in a small compartment with a swig open door - for easy
battery change - NO TOOLS REQUIRED
The next 7 positions are numbered from 100 to 0.1 all of these are % of the
maximum power marked on the element.
If an element is inserted that is marked 1000 watts. It will accurately
read from 1watt to 1000 watts full scale.
The 100 position reads 100% = 1000 watts full scale.
the 30 position reads 30% of the 1000 = 300 watts full scale
the 10 position reads 10% of the 1000 = 100 watts full
scale
the 3 position reads 3% of the 1000 = 30 watts full scale
the 1 position reads 1% of the 1000 = 10 watts full scale
the 0.3 position reads 0.3% of the 1000 = 3 watts full scale
the 0.1 position reads 0.1% of the 1000 = 1 watt full scale
When testing 27MHz 1000 watts or less the 4410-5 element is perfect 25-60MHz
1000watts.
If HF 2-30MHz then a 4410-3 element works up to 1000Watts.
If you run more then 1000 watts but less then 10,000 a 4410 meter with a
10,000w element can be used.
It works the same 100% - 0.1 % but scaled to the 10,000 watt max as follows.
The 100 position reads 100% = 10,000 watts full scale.
the 30 position reads 30% of the 10,000 = 3000 watts full scale
the 10 position reads 10% of the 10,000 = 1000 watts full
scale
the 3 position reads 3% of the 10,000 = 300 watts full scale
the 1 position reads 1% of the 10,000 = 100 watts full scale
the 0.3 position reads 0.3% of the 10,000 = 30 watts full scale
the 0.1 position reads 0.1% of the 10,000 = 10 watt full scale
This will require a 4410-4 element 2-30MHz which are more expensive but worth
the investment.
If you generate more then 10,000 watts I have high power meter sets here:
HF and 27MHz high power
ELEMENT NUMBER RATINGS AND COMMON USAGE:
4410-2 10,000 watts 450-2500KHz - old AM radio and
induction heating
4410-3 1000 watts 2-30MHz HAM and CB (will work on
160M)
4410-4 10,000watts 2-30MHz HAM and CB (will work on
160M)
4410-5 1000 watts 25-60MHz lower cost 27MHz and 6 meters
4410-6 1000 watts 50-200 MHz - 6 meters, 2 meters, aero mobile
4410-7 1000 watts 144-520MHz 2 meters, 1.25 meters, 70cm,
radio navigation
Even thought the 4410 series requires a battery it only reads average / dead
key NOT peak / swing.
They cannot be converted to read peak / swing.
