WORKMAN MODEL: SX-144/430

This SWR power meter is a measurement instrument with high performance. It can measure forward power (Pf), reflection power(Pr) and SWR simultaneously when testing and QSO transmitting. There are two scales to be optional. The antenna SWR can be read out directly at the crossing point of two scales of two pointer.

2. OPERATION

2.1 The virtual load of 50 ohmscan be used to obtain precision power measurement.

2.2 The forward power is indicated on the left-hand scale.

2.3 The reflection power is indicated on the right-hand scale.

2.4 The SWR can he read out at the crossing point of corresponding red line of thetwo pointers.

2.5 Connect 12VDC power source to 12VDC plug, the meter light will illuminate(Suitable to use in dark places). The red wire to "+" terminal and black wire to"-" terminal.
