2.2.8 RF Power Level
The TX20K RF transmission power level is user adjustable. There are
four different levels that can be chosen depending on the specific
application. A higher RF power level will allow for more reliable
transmissions over longer distances or in noisy RF environments. The
lower RF power levels will increase battery life longevity.
2.2.9 Power Supply Voltage Measurement
The TX20K measures and transmits its power supply voltage. The
tolerance of this measurement is +/-2%. The voltage is internally limited
to approximately 15V.
