Description: MFJ Standing Wave Meter Head Radio Power Meter with Backlight SWR Watt Meter 1.movable part: movable coil type2：Outlook：See attached picture for details Needle material: zinc white brass Needle color: black3. Direction of needle movement: from left to rightHand length: 49mm from the end of the needle to the center of the shaftHand width: 0.45sh 0.05 mm 4. Material of upper cover: PMOMA5. Lower cover material: ABS6. Magnet material: Alnico sintered magnet7. Frame material: SPCC8. Enameled wire material: UEW polyurethane copper wire9. Iridium placement: vertical10. Wire: two 200mm # 28 wire, a black, - . Article red. They are used to solder the LEDpositive/negative electrode. The wire ends need to have 5mm of copper exposed for soldering purposes.BacklightType 1: Two LEDs in series "6V, 20mA", connected to a resistor, 6200 1/2WType 2: Two LEDs in series "6V, 20mA", connected to a resistor, 1.3KQ 1/2W Standard test conditions: temperature 20C*, humidity 70%. If the test result will not be different, it can also be conducted under normal temperature and humidity. 1.Electricity flux degreeThe DC current required from the zero scale to the position shown on the scale.2. Maximum current level The DC current required from the zero scale to the full scale position.200uA (8%)3. Internal DC impedance: 7500 or 8%.4. Insulation impedanceWith 500V DC voltage test its insulation value, Iridium shell and electrical circuit insulation impedanceMore than 50MΩ.5. FrictionIridium on the sense current, and then slowly reduce to zero, the pointer indication position and the error of the center of the zero scale1mm6. Zero positionThe standard position of the electric cell, the center of the zero scale as the reference, the deviation between the location of the needle and the center of the zero scaleThe deviation between the position of the needle and the center of the zero scale is 1mm.7. BalanceWhen the Iridium is tilted 90 degrees relative to the standard position, the deviation between the position of the pointer and the center of the zero scale1mm8 Needle adhesionInstantaneously add the full scale current three times the overcurrent, 7 seconds later slowly reduce to the full current of 1/2, at this time, the fingerThe needle may stick at the bottom because of the difference in ambient temperature, but the needle should return to the specified range.Within 1/2 of the full scale9 Pointer oscillationThe maximum current is added in a linear manner within 5 seconds and then reduced to zero in a linear manner within 5 seconds.Pointer oscillation without stopping Abnormal conditions such as stopping Package1*MFJ standing wave meter head radio station power meter transmitter with backlight SWR Watt Meter Payment Method: PayPal preferred Shippment: 1.We provide free shipping to international via China Post Airmail, and every parcel will be registered with tracking number.
