Do Not Service Or Adjust Alone Under no circumstances should any person reach into an enclosure for the purpose of service or adjustment of equipment except in the presence of some- one who is capable or rendering aid. Safety Earth Ground An uninterruptible earth ground must be supplied

5、 from the main power source to test instruments. Grounding one conductor of a two conductor power cable is not sufficient protection. Serious injury or death can occur if this grounding is not properly supplied. Shock Hazard Do not attempt to disconnect an RF transmission line while RF power is pres

25、ermaline Wattmeter ix x Bird Model 6104/54/56 Termaline Wattmeter Figure 1 Models 6154 and 6156 Chapter 1 Introduction Purpose and Function This instruction book is intended for use by operators of the Models 6104, 6154 and 6156 Termaline Wattmeters. These wattmeters measure RF power under nonradiat

26、ing condi- tions. They provide a practically reflectionless, 50 ohm, line termination for up to 1000 MHz. Refer to the Specifications section for individual unit specifications. The Models 6104, 6154, and 6156 Wattmeters are intended for general field and laboratory use on CW, AM and FM modulation e

27、nvelopes. DescriptionThe Termaline Wattmeter consists of an RF coaxial load, dc cable, meter, crystal diode, and the housing. The load is comprised of an RF coaxial load resistor assem- bly encased in a finned radiator. A voltmeter is mounted to the radiator. A 3-1/2 foot coaxial cable, RG-58/U, con

28、nects the resistor voltmeter assembly to the meter. The meter is sealed and shock mounted on its housing. A crystal diode is furnished with the wattmeter. The diode is housed in the resistor-voltmeter assembly. Power input is measured by a four range crystal voltmeter indicating directly in watts. F

29、lipping the toggle switch de- termines the scale. Each scale has two ranges which are se- lected by plugging the crystal diode into the proper socket.

Diaphragm Replacement To replace a faulty diaphragm use the following procedure. 1.Stand the wattmeter vertically, with the back end up. 2.Loosen the clamp screw until the clamping band is released. 3.Remove the diaphragm cap

32、 and care- fully lift the diaphragm from the back end of the radiator tank. 4.Reverse the above procedure to assem- ble the unit. +Note: The coolant level should be about one inch below the top of the radiator cylinder. The coolant should be a clear to a light yellow color. If it is not, it may be c

33、ontaminated and should be replaced. Meter Replacement The microammeter is shock mounted in its housing. Do not attempt to repair the meter if it fails. Follow the procedure below to replace it. 1.Remove the meter case from the load. 15 Maintenance 2.Remove the dc cable and terminal strip from the me

34、ter by loosening the two 8-32 hex nuts on the meter termi- nals. 3.Place the meter face down on a smooth clean surface. 4.Press down evenly on the retainer ring. While pressing the retainer ring, unscrew the two 10-32 flat head ma- chine screws on the sides of the meter case. +Note: There is one scr

35、ew on each side. 5.Remove the meter with the retainer ring and sponge rubber strips. 6.To install a new meter, reverse the above procedure. Switch Replacement While performing the following procedure, refer to figure 5. 1.Remove the terminal board as de- scribed in the Meter Replacement paragraph. 2

36、.Unsolder the switch leads from the terminal board. Do not overheat the shunt resistor. 3.Remove the toggle switch by unscrew- ing the 15/32-32 face nut. 4.Reverse the preceding procedure to re- place the switch. DC Cable and Plug Service 1.Remove the cable from the plug by un- screwing the bushing

37、and pulling the cable out. The center conductor of the cable makes snug contact between the turns of the coil spring when assem- bled. 16 Bird Model 6104/54/56 Termaline Wattmeter 17 Maintenance Bend Braid Back 5/16 Typ. 3/16 7/32 5/32 Figure 6 DC Cable Assembly LOCKING RING 15/32 HEXNUT RED 15/32 H
