1000W ES320 V3 SWR Meter Power Meter VHF/UHF Dual Meter140-480MHz AVG/PEP Meter

  
1000W ES320 V3 SWR Meter Power Meter VHF/UHF Dual Meter140-480MHz AVG/PEP Meter. ES320 adopts Japanese famous power standing wave meter factory supporting meter head, better damping characteristics, face and is a double meter head design. Agricultural disk scale is more accurate. The net time to withstand the power of a larger HF band power detector, so you can rest assured that the use of HP and VHF/UHF I can be used at the same time, which is this. HP and VHF/UHF can be used at the same time, which is another big advantage of this product, ES320 proposes backlight and backlight switch, which is more convenient to use.

The back panel has 4 RF connectors (2 N-type each, 2 8L16 female commonly known as M seat), corresponding to the internal different detectors. According to the frequency you use to select the back of the said connector. TX connects to the transmitter (radio), ANT connects to the antenna or dummy load. There are two columns on the left and right side of the panel, and three of the buttons in each column are for selecting the volume. Respectively, the amount of xIx10X 100, respectively, is the dial readings.

Multiplier to determine the reading by the corresponding coefficient relationship. This is a positive 10W, positive 100W, positive 1KW. Panel left and right buttons in the bottom one is the mode switch, change the switch pressed within the access to the RC delay network is used to let the SSB signal. When applying, the meter needle machine fixed, convenient to measure the peak power.

If you measure FM, CW and other signals, please use AVG mode. If measuring SSB signal, please use PEP mode. If the first few steps are correct, when the transmitter is transmitting, you can see two meter needle swing on the meter head, the clockwise swing of the meter needle swing angle is larger. The clockwise one swings at a larger angle.

The counterclockwise needle swings at a smaller angle. The clockwise swinging needle indicates the forward power, and the counterclockwise swinging needle indicates the reverse power. The intersection of the two needles can be read as.

For example, if you choose X10 gear, the forward needle indicates 5, then the measurement result of forward power should be 5X10-50W, and the reverse needle points to 0.4, then the reverse power should be read as 0.5W. Then the reverse power should read 0.4X10=4W. Correctly select the power stop when measuring. The measurement result will be more accurate when the angle of rotation of the meter needle is larger1.
