Page 11: Chapter 1 Introduction
The silver plated brass RF line section is precision made to provide the best possible impedance match to the coaxial RF transmission line in which the wattmeter is inserted. At each end of the line section are Bird Quick-Change type RF connectors, which may be quickly interchanged with any other Bird... -
Page 12: Component Description
Optional Equipment The equipment available is a Carrying Case, QC Connectors, and Elements. Consult Bird Electronic Corporation for availability and pricing, or for special requirements. Power Requirements The Model 4410 & 4410A operates from one 9V alkaline battery. Approximate battery life is 24 hours of continuous usage. -
Page 13: Theory Of Operation
Theory Of Operation On any uniform RF line section there are voltages, currents and standing waves present when RF power is applied. These are the results of two travelling waves, forward and reflected. The characteristic impedance of these lines is a pure resis- tance, usually 50 ohms for useful lines. -
Page 15: Chapter 2 Installation
Chapter 2 Installation Portability When transporting the wattmeter, be sure the range switch is in the “off” posi- tion. In any other switch position, there is a slight drain on the 9 V battery. If the unit is to be inactive for more than 2 weeks, remove the battery to avoid dam- age from possible battery leakage. -
Page 16: Inserting In Transmission Line
Inserting in Transmission Line WARNING Exposure to RF power radiation and the possibility of RF shock or burns exist under some operating conditions. Always turn off transmitter when connecting or disconnecting wattmeter. Be sure transmission line is terminated into a load or antenna. When plug-in element is removed from the RF line socket, the line section center conductor is exposed. -
Page 17: Chapter 3 Operation
Operation Connectors The Series 4410 Wattmeter is normally supplied with two Female N type con- nectors which are of the Bird Quick-Change “QC” design. Other “QC” connectors are available as listed in the Replacement Parts List. Inserting Elements The plug-in element is inserted into the line section socket and rotated to either stop. -

RF Power Measurements WARNING Exposure to RF power radiation and the possibility of RF shock or burns exist under some operating conditions. Always turn off transmitter when connecting or disconnecting wattmeter. Be sure transmission line is terminated into a load or antenna. When a Plug-In Element is removed from the RF line socket, the line section center conductor is exposed. -
Page 19: Zero Meter
Zero Meter Before any power measurements are made, be sure the pointer rests on the zero mark. If not, set range switch to OFF position and adjust the zero adjustment screw clockwise or counterclockwise until the pointer rests at the zero mark. This adjusting screw is located at the bottom center of the meter bezel face, refer to figure 6. -
Page 20: Power Range Coverage
This correction is negligible (less than 1 percent) if the load has a VSWR of 1.2 or less. The Series 4410 Thruline Wattmeter used with a Bird Termaline Load Resistor of proper power rating forms a highly useful absorption wattmeter. Since the reflected power will be negligible, it will be unnecessary to rotate the element from the forward direction. - Page 21 Figure 7 VSWR Conversion Nomograph 2.0 2.5 3.0 4.0 5.0 25 30 40 50 150 200 400 500 FORWARD POWER - WATTS...

Page 23: Performance Notes
Performance Notes The Series 4410 wattmeter is sensitive to the presence of amplitude modulated signals and this can affect the accuracy. However, small amounts of AM (up to 10%) are tolerable, but for every 1% of AM, the inaccuracy of the reading may increase by up to 1% beyond the rated accuracy. -
Page 25: Chapter 4 Maintenance
Chapter 4 Maintenance The Series 4410 Thruline Wattmeter is of very rugged construction and requires little care and maintenance. Maintenance of the wattmeter is normally limited to cleaning. The amount of cleaning necessary can be minimized by keeping the plug-in element or the ship- ping slug in the socket of the line section. -

Page 27: Troubleshooting
Troubleshooting The Series 4410 Thruline Wattmeter is designed for independent, long term, trou- ble free operation. In case of malfunction or for replacement of a major compo- nent —particularly if it is still under warranty—return the unit to the factory. Do not tamper with the calibration setting or do other unauthorized maintenance work during the first year, or you may void the warranty. -
Page 28: Meter Replacement
Meter Replacement 1. Remove back cover. Loosen the two #8-32 nuts on the back of the meter that secure the meter leads. 3. Remove the leads. 4. Remove the two #10-32 oval head phillips screws that secure the meter shock ring. Note: These screws are located on each side of the meter housing just opposite the meter. -
Page 29: Customer Service
Any maintenance or service procedure beyond the scope of those in this chapter should be referred to a qualified service center. If the unit needs to be returned for any reason, request an RMA through the Bird Technologies website. All instruments returned must be shipped prepaid and to the attention of the RMA number. -
