Power meter with twin cross needle dispalay for hf, vhf, uhf

Thank you for your purchasing our product. This product is made under the stringent quality control. Should there

be any breakage in transit, please do not hesitate to contact the shop you purchased this product.

For your safety, read this manual carefully for proper handling and operation before using.

◆ Features

● 1.8-200MHz band and 140-525MHz band simultaneously can be measured based on two separate band meters.

● Cross needle display provides FWD, REF and SWR simultaneously.

● Passing Sensor helps power loss minimal. (Continuous Connection is OK)

● Beautifully illuminated when connected to your power supply.

● BNC Connector on the back side for monitoring modulated wave form and measuring frequency.

◆ Appearance & Components

① Display meter M1: indicates FWD, REF and SWR

② Measurement range selector button M1: changes the max power of FWD

③ Power supply input terminal: for illuminating the meter

④ Monitor output connector M1: for attenuated 30dB high-frequency power.

⑤ TR connector M1: SO-239(M-J) type Connector for the Power of Antenna

⑥ ANT connector M1: SO-239(M-J) type Connector for Antennas or Dummy Load

⑦ Earth terminal: for connecting the earth cable. TVI and BCI will be decreased when it's earthed.

⑧ Display meter M2: indicates FWD, REF and SWR

⑨ Measurement range selector button M1: changes the max power of FWD

⑩ AVG/PEP selector switch: AVG reads Average Voltage. PEP reads Peek Envelope Power

⑪ Monitor output connector M2: for attenuated 30dB high-frequency power.

⑫ TR connector M2: SO-239(M-J) type Connector for the Power of Antenna

⑬ ANT connector M2: SO-239(M-J) type Connector for Antennas or Dummy Load

● CMX-2300T is perfectly pre-tuned. Do not take the panel off or touch inside, it might cause the measurement

error. Especially, the RF censor has extremely low loss circuit so that you can't tune it with a common measuring

instrument.

● Never attempt to use the monitor a 15V or more. Failure to follow this could cause serious damage.

Page 1 ◆ Precautions for using ● CMX-2300T is perfectly pre-tuned. Do not take the panel off or touch inside, it might cause the measurement error. Especially, the RF censor has extremely low loss circuit so that you can’t tune it with a common measuring instrument.
Page 2 ● At 140~525MHz Band, put the antenna cable into M2 “TR” connector. Then, put the antenna feeding cable or dummy load into M2 “ANT” connector. ● When you use an Antenna Tuner with CMX-2300T, put CMX-2300T between Transceiver and an Antenna Tuner. Do not put it between an Antenna Tuner and cable. Failure to follow this might cause serious damage.
