Installation
Portability
CAUTION
Do not drop the Thruline Wattmeter equipment or submit it to hard blows. The
voltmeter circuitry or microammeter, even though it is shock mounted, may be
damaged by severe impact.
The Model 4308 is a portable instrument, and the housing is not designed for fixed
mounting. A strap is provided for carrying purposes. To protect the meter movement
during periods of transit, put the range switch in the “TRANSIT” position. This
effectively shunts the meter movement and dampens the pointer action.
Connections
WARNING
Leaking RF energy is a potential health hazard. Never attempt to connect or
disconnect equipment from the transmission line while RF power is being applied.
Severe burns, electrical shock, or death can occur.
Install the wattmeter in the 50 ohm transmission line as follows:
1. Attach the transmission line to the connectors on either side of the
wattmeter housing. It makes no difference which sides the RF
power source and the load are connected.

Note: Use of a short length of 50 ohm cable fitted
with the appropriate mating connectors may be useful
when inserting the wattmeter in the transmission line.
