Swr all function lighted test meter 500 watts load lap
Selling a New "WORKMAN" SX-144/430 all function test meter with 500 watt lap-lighted (suitable for dark places) all function Test Meter with instructions
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 points of two scales of two pointers.
* 1.1 Frequency range: 120MHz~500MHZ
* 1.2 Input/Output impedance:50
* 1.4 Forward/Reflection power ratio:5:1
* 1.5 Forward power: 10W, 100W, 500W (3 steps)
* 1.6 Reflection power: 2W, 20W, 100W (3 steps)
* 1.7 Power measuring accuracy: not more than + 10% (F.S.)
* 1.8 Meter illumination:12VDC
* 1.9 Size (LxBxH) 130mmx140mmx80mm
* 2.1 The Virtual load of 50 can 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 indicted on the left-hand scale
* 2.4 The SWR can be read out at the crossing point of corresponding red line of two pointer
* 2.5 Calculate the effective transmission power by subtracting reflection power (Pr) from forward power(Pf)
* 2.6 At "100W" and "500W" steps, the dial scale value multiplies 10 and 50 respectively to get power reading of 100W and 500W.
* 2.7 Connect 12 VDC power source to 12VDC plug, the meter light will illuminate(Suitable to use in dark place). The red wire to "+" terminal and black wire to "-" terminal.
* 3.2 Special connecting wire 1
