Nice used, looks new, VLF Power-SWR Meter. Battery is in good working condition. Comes with leads and Owners Manual. Precise Alignment Without Guesswork PLC Design— Specifically designed for use with powerline carrier equipment (10kHz to 500kHz). Dual Display— Two meters display forward power in Watts and dBm AND computed percent reflected power and SWR simultaneously. Fully Automatic— Internal computing circuits measure percent reflected power and SWR independent of the magnitude of forward power. Convenient Power Scales— Four Power ranges: 5 Watts, 15 Watts, 50 Watts and 150 Watts full scale. High Sensitivity— Full SWR computing with forward powers as low as 0.1 Watt. Built-in Power Sensor— For 10kHz to 500kHz measurements. Built-in Load— 50 Ohm, 50 Watt dummy load. Built-in Line Sampler— Directional line voltage sample at -20dBm level. For use with selective voltmeter in interference or multiple signal environments. Rugged Case— Fully dust sealed case with shock mounted taut-band meter meter movements. Micro Power Circuits— At least one years life on the easily obtainable 9 Volt internal batteries. Battery Saver— Closing lid turns the instrument off. Technical Specifications R.F. Power Front Panel Switches Ranges: 0-5 Watts (+25 to 37 dBm) Range: Four Position rotary type 0-15 Watts (+30 to +42 dBm) 0-50 Watts (+35 to +47 dBm) On-Off: Two position toggle switch. Closing cover pushes switch to OFF position. 0-150 Watts (+40 to 52 dBm) Voltage Sample: Two position toggle switch - Forward, Reflected. Scales: 0-5 W and 0-15 W -10 to +2 dB (50 Ohm Reference) Battery Check: Push Button Size 9 inches x 6 inches x 8 1/2 inches high Accuracy: 5% of full scale power into a 50 Ohm load Weight 5 pounds (less connecting cables) Frequency: 10kHz to 500kHz Response: 0.1 dB over full frequency range % Reflected Power and SWR Environment Ranges: 0-100% Reflected Power 1.0-5.0 Calibrated SWR Moisture: Splash proof with case closed Accuracy: 10% at SWR = 3.0 for power levels between -10dB and +2dB on any power range 5% at SWR = 3 for a -1dB power level, any power range. Dust and Dirt: Sealed when closed. All internal switch component are sealed against intrusion by dust when in use. Internal Batteries 9 Volt transistor battery (two required) NEDA 1604 (Eveready Type 216) Expected Life: > 2 years in normal use. Temperature: Storage: -40F to +150F Use: -10F to +120F Calibration Temp.: +75F Connectors BNC (4) - input, output, voltage sample and 50 Ohm dummy load.
